Accoring to the composition, it 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 system (600 series).
201: poor corrosion resistance, widely used as a cheap substitute for 300 series in China.
304: it is the most commonly used. products such as :corrosion-resistant containers, tableware,
furniture, railings, medical equipment.
316: the second most widely used steel type is mainly used in the food industry,clocks and jewelry,
pharmaceutical industry and surgical equipment.
430: Ferritic stainless steel, for decoration, for example for car accessories. Good moldability, but poor
temperature resistance and corrosion resistance.
