Q:I bought a steel pendant on eBay, but it turned out to be too shiny.I've read on a couple forums that if I leave it soaked in urine for 2 days, it will get duller.Now, if it really does get duller, will the pendant get rusty afterwards?So is the shiny surface the only thing that prevents it from rusting?Any simple, non-urine ideas on how to make it duller are welcome too.Thanks!: Stainless steel will rust under proper conditions. I live on a boat on salt water, trust me. If the urine works it won't be prone to rusting any more than before. It's not the shine that inhibits rusting with stainless steel, it the % of carbon in the steel, compared to regular steel. IF the urine works it's because it is acidic (a mild acid). Wash it with a small brush and some baking soda to neutralize the acid when your done. A much stronger acid would be swimming pool acid. (Muriatic acid) but be careful you might test a spot with a Q tip on the back. If you try Muriatic acid it would take seconds.Then wash in baking soda water to remove all acid.. SS

Q:How do steel coils contribute to the aerospace manufacturing industry?: Steel coils are essential in the aerospace manufacturing industry as they are used to produce various components, such as aircraft bodies, wings, and landing gear. These coils provide the necessary strength, durability, and resistance to extreme conditions required for aerospace applications. Additionally, steel coils can be easily shaped and welded, enabling manufacturers to create complex and precise structures, thereby enhancing the safety and efficiency of aircraft.

Q:steel welding with ms steel iron: Welding austenitic stainless steels to carbon and low alloy steels are established methods in the process and construction industries. Dissimilar metal welds involving stainless steels can be done using most full fusion weld methods, including TIG (Tungsten Inert Gas) and MIG (Metal Inert Gas). Weld procedures using filler (consumable) enable better control of joint corrosion resistance and mechanical properties. In selecting the weld filler, the joint is considered as being stainless, rather than the carbon steel. Over-alloyed fillers are used to avoid dilution of the alloying elements in the fusion zone of the parent stainless steel.

Q:Is it just because brass is reloadable? But what makes it reloadable? What does brass bring to the equation that the steel cased ammo can't do?: When 9mm was short I bought some steel Tula ammo, it was cheap and available. When at the range I was shooting it and it sounded different and felt different, way less kick. So I loaded up a mix of Tula and some Federal. Big difference between them. I also had failure to eject on the steel, then put brass in and did not have that problem. I do not buy cheap steel ammo anymore.

Q:What are the common methods of protecting steel coils from corrosion?: There exist various techniques commonly employed for safeguarding steel coils against corrosion. 1. Coating: To establish a barrier between the steel coil and the corrosive environment, a protective coating can be expertly applied. Multiple types of coatings, including paint, epoxy, or zinc, are available, each possessing superb corrosion resistance and obstructing the ingress of moisture and oxygen onto the steel surface. 2. Hot-dip galvanizing: Immersing the steel coil in a bath of molten zinc constitutes the hot-dip galvanizing method, resulting in the formation of a substantial zinc coating. This zinc coating acts as a sacrificial barrier, effectively shielding the steel against corrosion. Hot-dip galvanizing is especially advantageous in harsh environments or when prolonged exposure to the outdoors is anticipated. 3. VCI (Volatile Corrosion Inhibitor) packaging: VCI packaging entails encasing the steel coils in specially designed film or paper laced with volatile corrosion inhibitors. These inhibitors vaporize and form a protective layer on the steel surface, effectively preventing corrosion. VCI packaging is commonly employed for short-term storage or transportation of steel coils. 4. Desiccants: Moisture plays a significant role in the corrosion process. Consequently, utilizing desiccants such as silica gel or activated alumina aids in moisture absorption and the maintenance of a dry environment surrounding the steel coils. Desiccants are often combined with other protective methods to enhance corrosion protection. 5. Appropriate handling and storage: Employing proper practices for handling and storage significantly mitigates the risk of corrosion. Steel coils should be stored in a dry environment, distanced from moisture sources. Additionally, clean gloves should be utilized during handling to prevent the transfer of corrosive contaminants. Regular inspection and maintenance of the storage area are crucial for identifying and addressing potential corrosion risks. By employing one or a combination of these methods, steel coils can be effectively preserved against corrosion, guaranteeing their longevity and structural integrity.

Q:Why buy recycled steel and from where to buy?: Where you buy all your steel. The recycled and new steel are indistinguishable from each other. You won't recognize the one from the other. Same thing with glass. A certain percentage must be used glass, to enhance the quality of the total batch. Peace.

Q:does anyone out there know where to get a good deal on a pedal steel guitar? i am from northern indiana and i'm willing to travel some if i have to.i am just getting into pedal steel guitar and i really don't have any idea what i need. i don't know how to play a guitar (i do know how to play the piano and the drums) at all but i want to learn to play the pedal stell guitar and i can't do that without getting one first so, if anyone can help me out i would greatly appreciate it! :o): I agree with everything that Lester said. Another thought is to consider starting on a lap steel guitar rather than a pedal steel - its related, a little easier to learn on, and less expensive. Once you get proficient on the lap steel, you can move up to the pedal steel. Good luck!

Q:for my engineering project I have been asked to design a method of suspending a TV of weight 14Kg from a gantry, the TV must be 5m below the gantry. My team have decided to use as a suspension method a steel cylinder of outer diameter of 10cm and an inner diameter of 8, however we now need to work out both the max stress and strain and the actual stress and strain. and help would be useful: In most engineering calculations we have to make some assumptions about ideal behavior of a material otherwise we would not be able to simplify our equations to manageable sizes. Your steel cylinder (which I'll call a pipe) is made of a certain type of steel. That steel type has property tolerances listed in a steel manual to help you know about your steel before you begin. You'll need to know the cross-sectional area of the pipe and the weight of the TV to determine an average stress on the pipe. Obviously the weight of the TV is the force it generates. The force is its mass x gravitational acceleration. Since we typically think of steel as an elastic material, we think of it stretching like a rubber band or a spring. You pull it down with a TV and it deflects a certain amount, and will return to its original length when the TV is removed. It is typical to assume that all steel, regardless of its strength, has the same value for this elastic property. It is commonly referred to as the elastic modulus. This value will help you determine what type of strain occurs under what type of stress. So, once you have the stress, you can get the strain by using the elastic modulus. Once you have the strain you can determine the deflection based on the pipe length. Having the steel properties will help you determine how close your TV comes to stressing the pipe to its yield stress. If you reach a yield stress, your steel will deflect, but when you take the TV off it will not return to its original shape. I hope I've helped outline some of the things you'll need to do for the project, I tried not to give away specifics so that you can actually engage your brain around the project. Enjoy, learn a lot, and realize that this skill could easily turn into a career where you are designing projects that when done correctly save people's lives every day of the year.

Q:How are steel coils heat treated?: Annealing is the method used to heat treat steel coils, resulting in improved mechanical properties and overall performance. To achieve this, the coils are heated to a specific temperature and slowly cooled down. This process relieves internal stresses within the steel and enhances its performance. To begin the heating process, the steel coils are raised to a critical temperature, typically between 800°C and 900°C, depending on the desired outcome. They are then maintained at this temperature for a specific period of time, allowing for the transformation of the steel's microstructure. Once the desired time has passed, the heated coils are carefully cooled down in a controlled manner. This gradual cooling process is crucial as it allows for a uniform and refined microstructure. It also helps prevent the formation of internal stresses that could weaken the steel. The annealing process can be conducted in various atmospheres, such as air, nitrogen, or hydrogen. The choice of atmosphere depends on the specific requirements and properties desired for the steel coils. For example, annealing in a protective atmosphere like nitrogen or hydrogen can prevent oxidation or decarburization of the steel surface. In conclusion, annealing is a crucial step in heat treating steel coils, resulting in improved mechanical properties, enhanced formability, and the desired characteristics for industrial applications.

Q:How are steel coils inspected for uniformity?: Steel coils are inspected for uniformity through visual examination and various non-destructive testing techniques. These include measuring the dimensions and weight of the coils, checking for any surface defects or damages, and conducting magnetic particle or ultrasonic testing to detect any internal flaws or irregularities. Additionally, the coils may undergo chemical composition analysis to ensure uniformity in the steel's properties.
