300 series and 200 series of differences present in the Chinese market are mainly stainless steel 300 series and 200 series, the difference lies in the number of chemical elements nickel content, which caused them a huge difference in performance and price. In the current nickel price level, low nickel content stainless steel 200 series 300 series stainless steel price is only about half the corrosion and toughness properties are far better than the 300 series stainless steel, stainless steel furniture net, only applies to kitchenware field, food processing, etc., if used in the fields of construction, medical equipment, etc., there will be a big risk. Nickel content of about 1% of the 200 series of products, can not withstand normal atmospheric corrosion. People often magnets stainless steel, to validate the merits and authenticity, do not attract non-magnetic, considered a good, genuine; sucked by magnetic, it is considered counterfeit fakes. In fact, this is an extremely one-sided, no practical method to identify errors. Stainless steel variety, according to the organizational structure at room temperature can be divided into austenitic or ferritic and martensitic. Austenitic type is non-magnetic or weakly magnetic, and martensite or ferrite is magnetic (but not so strong as iron products). Usually used as a decorative tube plate austenitic stainless steel most of the material 304 and 201, in general, is a non-magnetic or weakly magnetic, stainless steel furniture, but the chemical composition fluctuations caused by smelting or processing may occur in different magnetic state, But this can not be considered counterfeit or substandard, which is what causes it? The above mentioned austenite is non-magnetic or weakly magnetic, high-grade stainless steel furniture, and martensite or ferrite is magnetic, due to improper heat treatment smelting segregation or custom stainless steel furniture, it will result in austenitic 304 and 201 stainless steel in a small amount of martensite or ferrite. Thus, the 304 and 201 stainless steel with a weak magnetic will. 300 series and 200 series of differences present in the Chinese market are mainly stainless steel 300 series and 200 series, the difference lies in the number of chemical elements nickel content, which caused them a huge difference in performance and price. In the current nickel price level, low nickel content stainless steel 200 series 300 series stainless steel price is only about half the corrosion and toughness properties are far better than the 300 series stainless steel, is only available in kitchenware and food processing field, if used in the fields of construction, medical equipment, etc., there will be a big risk. Nickel content of about 1% of the 200 series of products, can not withstand normal atmospheric corrosion.
