Round 10mm 20mm 301L 310S Stainless Steel Bars Tisco Baosteel

200 series - chromium nickel manganese austenitic stainless steel
300 series - chromium nickel austenitic stainless steel
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.
302 - the corrosion resistance is the same as 304, and the strength is better due to the relatively high carbon content.
303 - make it easier to cut by adding a small amount of sulfur and phosphorus.
304 - i.e. 18 / 8 stainless steel. The GB brand is 06cr19ni10.
309 has better temperature resistance than 304.
316 - after 304, the second most widely used steel is mainly used in food industry and surgical equipment. Molybdenum is added to
obtain a special corrosion-resistant structure. Because it has better chloride corrosion resistance than 304, it is also used as
"marine steel". SS316 is usually used in nuclear fuel recovery units. Grade 18 / 10 stainless steel generally meets this
application grade. [1]
Model 321 - other properties are similar to 304 except that the risk of weld corrosion of the material is reduced due to the
addition of titanium.
400 series - Ferritic and martensitic stainless steel
408 - good heat resistance, weak corrosion resistance, 11% Cr, 8% Ni.
409 - the cheapest model (British and American), usually used as automobile exhaust pipe, is ferritic stainless steel (chromium
steel).
410 martensite (high strength chromium steel), good wear resistance and poor corrosion resistance.
416 - sulfur was added to improve the processability of the material.
420 - "cutting tool grade" martensitic steel, similar to the earliest stainless steel such as Brinell high chromium steel. It is
also used for surgical tools, which can be made very bright.
430 ferritic stainless steel for decoration, such as automotive accessories. Good formability, but poor temperature resistance and
corrosion resistance.
440 high strength cutting tool steel, with slightly higher carbon content, can obtain higher yield strength after appropriate heat
treatment, and the hardness can reach 58hrc. It is one of the hardest stainless steels. The most common application example is
"razor blade". There are three common models: 440A, 440b, 440C, and 440f (easy to process).
500 series - heat resistant chromium alloy steel.
600 series - Martensitic precipitation hardening stainless steel.
630 - the most commonly used precipitation hardening stainless steel model, usually also known as 17-4; 17%Cr,4%Ni.
