Carbon steel and stainless steel difference:
1, the color is different: stainless steel containing chromium and nickel metal more, the appearance of the color of silver bright. Carbon steel is mainly carbon and iron alloy, other metal elements are relatively few, the appearance of the main color is the color of iron, color will be much darker.
2, the texture is different: stainless steel contains other metal elements, the surface is smooth, carbon steel contains iron carbon NIA, there is the essence of iron, the surface is not smooth stainless steel.
3, magnetic difference: carbon steel surface with magnetic, can be magnet adsorption. Stainless steel has no magnetism under normal conditions and will not be absorbed by magnets.
4, carbon elements are different: carbon steel mainly refers to mechanical properties depend on the carbon content of steel, and generally do not add a lot of alloy metal elements of steel, which contains less than 2% WC carbon, stainless steel in order to maintain corrosion resistance, carbon content is low, the maximum is not more than 1.2%.
5, different alloy content: carbon steel contains very few alloying elements, only a small amount of silicon, manganese, sulfur, phosphorus. Stainless steel contains more gold elements, the main chromium nickel element more than 12%.
6, corrosion resistance is different: carbon steel contains less alloy elements, corrosion resistance is weak, stainless steel contains more chromium and nickel metal, has strong corrosion resistance.
