430 is a ferritic stainless steel, 430 16Cr is a representative type of ferritic steel, thermal expansion rate, excellent formability and oxidation resistance. Heat-resistant appliances, burners, household appliances, type 2 cutlery, kitchen sinks, exterior trim materials, bolts, nuts, CD rods, screens. Because of its chromium content, it is also called 18/0 or 18-0. Compared to 18/8 and 18/10, the chromium content is slightly lower and the hardness is reduced accordingly.
410 hot rolled stainless steel coil has good corrosion resistance and machinability. It will harden after heat treatment. It is generally used to make blade and valve tools. 410 stainless steel has good corrosion resistance and machining performance. It is a general purpose steel and cutting tool steel. 410S is a steel grade that improves the corrosion resistance and formability of 410 steel.
321 stainless steel is a high-strength steel, which is more resistant to high temperatures than 316L. It has better corrosion resistance in organic acids at different concentrations and at different temperatures, especially in oxidizing media. 321 stainless steel is often used in the manufacture of ducts, acid-resistant containers and wear-resistant equipment.
High temperature resistant stainless steel, also known as 310S (0Cr25Ni20) stainless steel, is austenitic chromium-nickel stainless steel, has good oxidation resistance, corrosion resistance, because a higher percentage of chromium and nickel, so that has much better creep strength, Can continue to work at high temperatures, with good high temperature resistance.
201 stainless steel has certain acid and alkali resistance, high density, polished without bubbles, and no pinholes. It is a high-quality material for the production of various watch cases and watch cases.
