- Q: Eutectoid Steel
- Eutectic steel is used to produce pearlite, bainite, spheroidite and martensite steels. Those steels vary in strength, hardness and ductility. One uses martensite steel for example in razor blade manufacturing. Of course there is no end to the various uses of these steels.
- Q: I have a steel plate 3' long x 2 wide x 3/16 thick. I have a 1/2 diameter hole with the center 3/4 from the end. Tensile strength is 38,000psi. A chain goes through the hole and is connected to a load. how does one determine how much tension the chain can have before it rips through the hole?
- Assuming that the chain can take the breaking load of the plate, the plate will fail at the area between the hole and the end, in double shear. The shear strength of the material should therefore be known for us to be able to calculate the breaking force. Approximately, the shear strength of steel is about 60% of the tensile strength. For ordinary mild steel the tensile strength is about 60,000 psi, not 38,000 psi. 38,000 psi is just about the yield point of mild steel. Using 60,000 psi tensile strength, the approximate shear strength of steel therefore is 36.000 psi. The net area between the hole and the end of the plate is: A = 3/16(3/4 - 1/4) = 0.09375 in^2 The force necessary to rip through the area which is also the tension on the chain is: T = 2 x 0.09375 x 36,000 = 6750 lbs
- Q: Several reading methods of steel tape measure
- Precise steel tape factory and after a period of time must go through the verification and indicate the verification of temperature, tension and feet. Feet marked on the length of its nominal length, and the difference between the actual length is called length correction delta l ruler by different tension will make feet long. To avoid this change requires the use of steel tape according to the scale mark force of steel tape. At different temperature the foot will change with the temperature so it is necessary to use t as variable function to represent the feet long, this is the ruler length equation, its general form:
- Q: doesnt steel rust?
- Iron mixed with other metals:
- Q: What are the different grades of steel used for coils?
- The different grades of steel used for coils vary depending on the specific requirements and applications. Some common grades include low-carbon steel (e.g., ASTM A36), medium-carbon steel (e.g., ASTM A516), high-strength low-alloy (HSLA) steel (e.g., ASTM A572), and stainless steel (e.g., 304 or 316). Each grade offers distinct properties such as strength, corrosion resistance, and formability, enabling manufacturers to choose the appropriate one based on their needs.
- Q: how much pressure can steel withstand? and how much pressure can concrete withstand? per m3 or cm3? thanks
- A common allowable stress for steel is 24,000 psi for A36 steel. Note that allowable stress is a working stress that is less than ultimate stress the stress at which the material will rupture. This allowable stress keeps the steel within the elastic range. Concrete allowable stress is typically around 3000 psi. Concrete, though, being a mixed material has variable values for allowable stress. Reinforced concrete design theory suggests that concrete should not be considered to be able to carry much, if any, tensile force. This explains why you will see steel rebar or reinforcing bars cast in to the concrete. The steel is there to carry any tensile forces, while the concrete is there to carry compression forces. This is a VERY basic explanation. There are entire books on both of these subjects...
- Q: I bought a Remington 870 super mag last fall and wanted to to switch to non-tox steel loads. The gun came with a modified rem choke. I know that not all chokes are qualified to handle steel. It doesn't say anywhere on the choke no steel I was just wondering if anyone out there knew for sure that those chokes that the guns come with won't get damaged be steel.
- No problem. With steel shot you would use one choke size LARGER. If you want a full choke type pattern ( 70 % in a 30 inch circle at 30 yards ) you use a modified choke. if you want a modified pattern use the improved cylinder. Don't use the full or extra full. This is because when using lead shot it deforms, and fits through the choke, steel shot does not deform, it remains rigid. The first indication of a problem will be a slight bulge in the barrel right behind the choke. Check that once in a while, if you ever have that problem, it is not drastic if caught early. Today's modern shotguns all have been set up for steel shot. The old ones such as Belgium Brownings, are a no go. Funny thing, when we first began importing steel shot, I asked a Browning Tech guy if he thought I could fire steel out of my Belgium Browning. He said not a good idea, however, if you have the Citori or other Japanese made Brownings, no problem. Hummm, my expensive Brownings, no, but Japanese made OK, this is because the Japanese steel was higher quality. Geeeze. I was shocked.
- Q: What are the different types of coil slitting machines?
- In the market, one can find various coil slitting machines, each designed to meet specific requirements and preferences. Some commonly used types are as follows: 1. Rotary shear slitters: These machines employ rotary knives mounted on a rotating drum to slice the coil into narrow strips. They are perfect for high-speed operations and can handle large quantities of material. 2. Loop slitters: Loop slitting machines pass the coil through a loop to maintain tension and prevent material damage during the slitting process. They are suitable for delicate materials or those prone to deformation. 3. Turret slitters: Turret slitting machines have multiple sets of slitting knives mounted on a rotating turret. This enables quick and easy switching between various slitting configurations, reducing downtime and increasing productivity. 4. Drag slitters: Drag slitting machines utilize a stationary knife and a moving clamp to hold and pull the coil through the cutting process. They are versatile and can handle a wide range of materials, including thick or heavy coils. 5. Crush slitters: Crush slitting machines employ a set of opposing rollers to crush and cut the coil material. They are commonly used for softer materials or those that are challenging to cut with traditional knives. 6. Laser slitters: Laser slitting machines make use of a high-powered laser beam to precisely cut through the coil material. They offer unparalleled accuracy and are suitable for high-end applications or materials with complex shapes. Each type of coil slitting machine has its own advantages and limitations. The choice of machine depends on factors such as the type of material, required speed, desired accuracy, and production volume.
- Q: What is the maximum stacking height for steel coils?
- The maximum stacking height for steel coils depends on various factors such as the weight and size of the coils, the strength of the supporting structure, and the safety regulations and guidelines in place. It is recommended to consult the manufacturer's specifications and industry standards to determine the appropriate maximum stacking height for steel coils in a specific situation.
- Q: Hi can someone help me pleaseis there any available data for mechanical behaviour of recycled steel, i need to compare them with new steel.
- Most recycled steel is blended with new steel at the steel mill. Scrap steel that is reused directly doesn't change it properties because it has been used. That is unless it has been in certain environments such as ones with hydrogen, hydrogen sulfide etc. Then the steel can become brittle. You might look for information on the National Association of Corrosion Engineers (NACE). They have lots of information on metals and what causes problems.
