Product Description
300 Series Stainless Steel, The most widely used austenite steel is the 304, also known as 18/8 for its composition of 18% chromium and 8% nickel. 304 may be referred to as A2 stainless (not to be confused with AISI grade A2 air hardening alloy tool steel containing about 5% chromium). The second most common austenite steel is the 316 grade, also referred to as A4 stainless and called marine grade stainless, used primarily for its increased resistance to corrosion. A typical composition of 18% chromium and 10% nickel, commonly known as 18/10 stainless, is often used in cutlery and high-quality cookware. 18/0 is also available.
300 Series - Chromium-Nickel Austenitic Stainless Steels
301—Good ductility, used for molded products. Machine speed hardening is also possible. Good weldability. Wear resistance and fatigue strength are better than 304 stainless steel.
302-corrosion resistance is the same as 304, because the carbon content is relatively high and the strength is better.
303—By adding a small amount of sulfur and phosphorus to make it more machining.
304—that is, 18/8 stainless steel. The GB grade is 06Cr19Ni10.
309—has better temperature resistance than 304.
316—After 304, the second most widely used steel grade, mainly used in the food industry and surgical equipment, adding molybdenum to obtain a special structure that is resistant to corrosion. Because of its better resistance to chloride corrosion than 304, it is also used as "marine steel". SS316 is usually used in nuclear fuel recovery units. Grade 18/10 stainless steels generally also meet this application level. [1]
Model 321—Similar to 304 except that the risk of corrosion in material welds is reduced due to the addition of titanium.
