The use of stainless steel is
The following are all models and uses of stainless steel:
Aug 07,2024
One, 301 - good ductility, used for molding products. It can also be hardened by machine speed. Good weldability. The wear resistance and fatigue strength are better than 304 stainless steel.
Second, 302 - corrosion resistance is the same as 304, and the strength is better because the carbon content is relatively high.
Iii, 303 - By adding a small amount of sulfur, phosphorus to make it more cutting processing.
Four, 304 - i.e. 18/8 stainless steel. The GB brand is 0Cr18Ni9.
Fifth, 309 - has better temperature resistance than 304.
Sixth, 316 - after 304, the second most widely used steel grade, mainly used in the food industry and surgical equipment, adding molybdenum element to make it obtain a special structure resistant to corrosion. Because it has better resistance to chloride corrosion than 304, it is also used as "Marine steel". SS316 is commonly used in nuclear fuel recovery units. Grade 18/10 stainless steel is also usually suitable for this application level.
Vii, 321 - Other properties similar to 304 except that the addition of titanium reduces the risk of corrosion in the weld of the material.
Viii, 400 series - ferritic and martensitic stainless steel
Ix, 408 - Good heat resistance, weak corrosion resistance, 11% Cr, 8% Ni.
X, 409 - the cheapest model (Anglo-American), commonly used as an automobile exhaust pipe, is a ferritic stainless steel (chromium steel).
11, 410 - martensite (high strength chromium steel), good wear resistance, poor corrosion resistance.
Xii, 416 - The addition of sulfur improves the processing properties of the material.
Xiii, 420 - "cutting tool grade" martensitic steel, similar to Brinell high chromium steel this earliest stainless steel. Also used in surgical knives, can be made very bright.
14, 430 - ferritic stainless steel, used for decoration, such as in car accessories. Good formability, but poor temperature resistance and corrosion resistance.
15, 440 - high strength cutting tool steel, slightly higher carbon content, after appropriate heat treatment can obtain a high yield strength, hardness can reach 58HRC, is one of the hardest stainless steel. The most common example is the "razor blade". There are three common models: 440A, 440B, 440C, and 440F (easy to process).
Xvi, 500 series - heat-resistant chrome alloy steel.
