Classification characteristics of stainless steel

There are many types of stainless steel plates , which can be divided into several categories according to the organizational structure at room temperature:

1. Austenitic type (300 series, chromium-nickel): such as 304, 321, 316, 310, etc., 200 is a low-cost and low-cost stainless steel with low nickel, and also austenite

2. Martensite or ferrite type (400 series): such as 430, 420, 410, etc .; austenite type is non-magnetic or weakly magnetic, and martensite or ferrite is magnetic.


Hardware products must consider its rust prevention, hardness, and processing performance. 201 202 301 304 316 has been improved in order in rust resistance and heat resistance. 202, 304, 316 density: 7.74, 7.93, 7.98. 316 stainless steel plate is a brand under the American standard. It belongs to stainless, heat-resistant and corrosion-resistant steel. It is austenitic stainless steel, which is better than 304 stainless steel. For the national standard (GB), it is 0Cr17Ni12Mo2.


The commonly used stainless steel plates are divided into two types, 201 and 304, which are actually different in composition. Among them, 304 stainless steel plate is the most widely used as stainless steel heat-resistant steel, which is austenitic stainless steel. The 400 series is martensitic stainless steel. 304 stainless steel is not magnetic, 400 series is magnetic. But some of the 304 why the magnetite can suck up, because the magnetite can feel the micromagnetism is not a problem (the austenite may also have micromagnetism in the cold processing or smelting improperly). Relative to 400 series, 304 nickel content is high, about 8-10%.

系列—铬-镍奥氏体不锈钢 300 series—chrome-nickel austenitic stainless steel


Model 301—Good ductility, used for molded products. It can also be made quickly by machining

Fast curing. Good weldability. Abrasion resistance and fatigue strength are better than 304 stainless steel.

Model 302—Corrosion resistance is the same as 304, because the carbon content is relatively high and the strength is better.

Model 303—It is easier to cut than 304 by adding a small amount of sulfur and phosphorus.

Model 304—General model; 18/8 stainless steel. The GB grade is 0Cr18Ni9.

Model 309—has better temperature resistance than 304.

Model 316—after 304, the second most widely used steel type, mainly used in the food industry and surgical equipment, the addition of molybdenum element to 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 usually used in nuclear fuel recovery equipment. 18/10 grade stainless steel usually also meets this application level.

Model 321—Similar to 304 except that the addition of titanium reduces the risk of corrosion of the material's welds.
