Stainless steel has unique strength, high wear resistance, superior anti-corrosion performance and otherexcellent characteristics.
304: general model; That\'s 18/8 stainless steel. Products such as: corrosion - resistant containers, tableware, furniture,
railings, medical equipment. The standard composition is 18% chromium and 8% nickel. It is a non-magnetic stainless steel which cannot be changed by heat treatment method. GB brand is 06Cr19Ni10.
310:Excellent high temperature oxidation resistance, the highest service temperature 1200℃.
316: After 304, the second most widely used steel, mainly used in the food industry, watch jewelry, pharmaceutical industry and surgical equipment, the addition of molybdenum to give it a special corrosion resistant structure. It is also used as "Marine steel" because of its better resistance to chloride corrosion than 304. SS316 is usually used in nuclear fuel reprocessing units.
321: similar to 304 except that the addition of titanium reduces the risk of weld corrosion.
Add stabilizer element niobium, suitable for welding aeronautical appliance parts and chemical equipment.
400series: Ferrite and martensitic stainless steel, manganese free, can replace 304 stainless steel to a certain extent
410:Martensite (high strength chromium steel), good wear resistance, poor corrosion resistance.
430:Ferritic stainless steel, for decorative purposes, e.g. automotive accessories. Good formability, but poor temperature and corrosion resistance.
440: High strength cutting tool steel, slightly higher carbon content, after proper heat treatment can obtain high yield
strength, hardness can reach 58HRC, belongs to the hardest stainless steel. The most common example is the "razorblade". There are three commonly used models :440A, 440B, 440C, and 440F(easy to process). It is widely used in industries,
food machinery, electromechanical industry, household electrical appliances industry and home decoration.
