Stainless steel plate is divided into: cold rolled stainless steel plate, hot rolled stainless steel plate and medium and heavy plate.
1. Thickness of cold-rolled stainless steel plate: 0.3-6.0mm Size and specification of cold-rolled stainless steel plate: 1000*2000 1220*2440 1220*3050 1220*4000.
1500*3000 1500*6000 width and fixed length can be opened and leveled according to requirements.
2. Thickness of hot-rolled stainless steel plate: 3.0-16.0mm Size and specification of hot-rolled stainless steel plate: 1500*6000 1800*6000 2000*6000 width fixed length.
3. Thickness of medium and heavy plate: 18-100mm Medium and heavy plate size specification: 1500*6000 1800*6000 2000*6000 The length and width can be cut as needed.
General size: 1000*2000, 1219*2438, 1500*6000, 1800*6000 Ordinary fixed length: 1000* fixed length, 1219* fixed length, 1500* fixed length, 1800* fixed length Any fixed length (generally the price will be higher ) The above unit is mm.
Model 301 - Good ductility for shaped products. It can also be hardened by mechanical processing. Good weldability. Wear resistance and fatigue strength are better than 304 stainless steel.
Model 302 - Corrosion resistance as 304, better strength due to relatively high carbon content.
Model 303 - It is easier to cut than 304 by adding a small amount of sulfur and phosphorus.
Model 304 - General purpose model; i.e. 18/8 stainless steel. GB grade is 0Cr18Ni9.
Model 309 - Better temperature resistance than 304.
Model 316 - the second most widely used steel after 304, mainly used in the food industry and surgical equipment, with the addition of molybdenum to obtain a special structure that is resistant to corrosion. Because of its better resistance to chloride corrosion than 304 stainless steel, 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.
400 Series - Ferritic and Martensitic Stainless Steels
Model 408 - Good heat resistance, weak corrosion resistance, 11% Cr, 8% Ni.
Model 409 - The cheapest model (British and American), commonly used as a car exhaust pipe, is a ferritic stainless steel (chrome steel).
Model 410 - Martensitic (high strength chromium steel) with good wear resistance and poor corrosion resistance.
Model 416 - The addition of sulfur improves the processability of the material.
Model 420 - "cutting grade" martensitic steel, the earliest stainless steel similar to Brinell. Also used in surgical knives, can do very bright.
Model 430 - ferritic stainless steel for decorative use, e.g. for car accessories. Good formability, but poor temperature and corrosion resistance.
Model 440-high-strength cutting tool steel, with slightly higher carbon content, can obtain higher yield strength after proper heat treatment, and the hardness can reach 58HRC, which is one of the hardest stainless steels. The most common application example is "razor blades". There are three commonly used models: 440A, 440B, 440C, and 440F (easy processing type).
500 Series - Heat Resistant Chromium Alloy Steel.
600 Series - Martensitic Precipitation Hardening Stainless Steel.
Model 630 - The most commonly used precipitation hardening stainless steel model, also commonly called 17-4; 17%Cr, 4%Ni. , Chromium 18-20.
