200 Series 300 Series Stainless Steel Window Mesh 16 Mesh Grasshopper Proof screen
Stainless steel can be divided into Cr series (400 series), Cr-Ni series (300 series), Cr-Mn-Ni (200 series), heat-resistant chromium alloy steel (500 series) and precipitation hardening series (600 series) according to the composition.
200 Series: Chromium-Manganese-Nickel
201, 202, etc.: Substitute manganese for nickel, which has poor corrosion resistance and is widely used as a cheap substitute for 300 series in China
300 Series: Chromium-Nickel Austenitic Stainless Steels
301: Good ductility, used for molding products. It can also be hardened by mechanical processing. Good weldability. 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: It is easier to cut than 304 by adding a small amount of sulfur and phosphorus.
304: Universal model, 18/8 stainless steel. Products such as: corrosion-resistant containers, tableware, furniture, railings, medical equipment. The standard composition is 18 % chromium plus 8 % nickel. It is a stainless steel that is non-magnetic and cannot be changed by heat treatment. The GB grade is 06Cr19Ni10.
304 L: The same characteristics as 304, but with low carbon, it is more corrosion-resistant and easy to be heat-treated, but has poor mechanical properties. It is suitable for welding and products that are not easy to be heat-treated.
304 N: The same characteristics as 304, it is a nitrogen-containing stainless steel, nitrogen is added to improve the strength of the steel.
309: Compared with 304, it has better temperature resistance, and the temperature resistance is as high as 980 ℃.
309 S: It has a lot of chromium and nickel, so it has good heat resistance and oxidation resistance. Products such as heat exchangers, boiler components, and jet engines.
310: Excellent high temperature oxidation resistance, the maximum operating temperature is 1200 ℃.
316: After 304, the second most widely used steel grade, mainly used in the food industry, watch accessories, pharmaceutical 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.
316 L: Low carbon, so it is more resistant to corrosion and easy to heat treatment. Products such as chemical processing equipment, nuclear power generators, and refrigerant storage tanks.
321: Similar to 304, except that the risk of corrosion of material welds is reduced due to the addition of titanium.
347: Add stabilizing element niobium, suitable for welding aircraft parts and chemical equipment.
