- Q:How are steel coils inspected for thickness variations?
- Steel coils are inspected for thickness variations using non-contact measurement techniques such as laser or ultrasonic sensors. These sensors are capable of accurately detecting and measuring the thickness of the steel coils at various points along their length. The collected data is then analyzed to identify any variations in thickness and ensure the quality and consistency of the steel coils.
- Q:i like stainless steel guns, especially the SW 686 .357, i plan on getting one but my question is would polishing the stainless steel make the gun more prone to corrosion over leaving it as it is? and will the polished surface appear uneven after use and sitting? obviously all metal takes some sort of upkeep but is polished more high maintenance than non-polished?
- I use Mothers Mag polish also. The shine you get depends on the effort.... If you buffed a mirror finish it will dull in time... More work brings it back. On a SW you won't take off enough to make any difference as far as metal holding oil. I use a little Mothers whenever I clean my stainless revolver.... Takes the carbon ring off the cylinder face... I use old cotton socks and t shirts. You could use a Dremel to work the mag wheel polish if you want a bright finish.
- Q:What are the various surface finishes available for steel coils?
- Steel coils offer a range of surface finishes, each with its own properties and uses. Some commonly used finishes include: 1.

- Q:How do steel coils compare to aluminum coils?
- Steel coils and aluminum coils have several key differences that make them suitable for different applications. Firstly, steel coils are known for their strength and durability. They can withstand high temperatures and are less prone to damage compared to aluminum coils. This makes steel coils ideal for heavy-duty industrial applications that require robust materials, such as construction, automotive manufacturing, and oil and gas industries. Steel coils are also more resistant to corrosion, making them suitable for outdoor use in harsh environments. On the other hand, aluminum coils are lighter and have a higher strength-to-weight ratio compared to steel coils. This makes them perfect for industries where weight is a critical factor, such as aerospace and transportation. Aluminum coils are also more malleable, allowing for easier shaping and forming, which is advantageous in industries like packaging and consumer electronics. Moreover, aluminum coils have better thermal conductivity than steel coils, which makes them more efficient in heat transfer applications. This property is beneficial in industries like HVAC (heating, ventilation, and air conditioning) and refrigeration, where efficient heat exchange is crucial. In terms of cost, steel coils are generally more affordable compared to aluminum coils due to the lower cost of raw materials. However, aluminum coils can offer long-term cost savings as they require less maintenance and have a longer lifespan due to their resistance to corrosion. In conclusion, the choice between steel coils and aluminum coils depends on the specific requirements of the application. Steel coils are preferred for their strength, durability, and corrosion resistance, while aluminum coils excel in lightweight applications, heat transfer, and malleability.
- Q:When i was 15 i got caught steeling at Super A yes i know i cant believe it. They didnt call the cops or anything they released me to my aunt they took my name and adress and everythimg they said it wouldnt be on my record. But I'm not so sure. Will it be on my record if they didn't call the cops?i live in california. Is there any way i can check my record?
- Steeling? What's that? Did you take a piece of steel and weld it? I am confused?
- Q:I want to know where cold formed steel framing is used, is every steel frame we see in a construction sites like houses, building and bridges cold formed steel frames? or hot formed steel framing?I also read that cold formed steel framing is used for floors, is the steel frame beneath the floor's concrete cover?Thank u very much!!
- It will vary from location to location. A possible way of telling is how the material is joined. If the material is riveted together it is likely cold rolled. If the material is welded then its probably normalized steel (possibly annealed but less likely). Cold rolling increases the yield strength of the material so less of it is needed. However, it also make the material more brittle. Welding creates defects in the region surrounding the weld and these are more likely to grow and cause failure in a cold rolled steel than a normalised or annealed steels. In addition the heat from the welding will change the microstructure that was deliberately introduced by the cold rolling process resulting in a localised drop in yield strength. Normalised and annealed steels are more ductile and tougher than Cold rolled steel but they have a lower yield strength. Because they are tough and ductile they are less sensitive to crakcs and defects so welding won't lead to as big a reduction in strength. Another possible consideration is the environment they are used in. Steels exhibit a transition temperature (actually more like a range) where they go from behaving like a ductile material to a brittle material. A well known example of what this can cause are the Liberty ships in WW2 (Supply vessels from the US to the UK). These were made by welding together sheets of cold rolled steel to form one continuous Hull. Unfortuantely the transiton temperature of the steel taht was sued was around 4 degrees while the Baltic Ocean is about 0 degrees. As a result small cracks would grow and then when the reached a critical size they would tear through the ship at the speed of sound in the metal (1500m/s) and these massive cargo ships would literally snap like twigs. So, if the steel is being used somewhere really cold its unlikely to be Cold rolled too.
