We are committed to providing customers with high-quality and low-price steel products as its goal, and strives to create value for customers as its own responsibility.
1, the color is different:
stainless steel containing chromium and nickel metal is more, the appearance of color is much silver bright color. Carbon steel is mainly carbon and iron alloy, other metal elements are relatively small, the main color of the appearance is the color of iron, the color will be much darker.
2, the grain is different:
stainless steel contains other metal elements, the surface is smooth, carbon steel contains iron carbon nia, the essence of iron, the surface is not smooth stainless steel.
3, magnetic different:
carbon steel surface with magnetic, can be adsorbed by magnets. Stainless steel is not magnetic under normal circumstances and will not be absorbed by magnets.
4, different carbon elements:
carbon steel mainly refers to the mechanical properties depend on the carbon content of steel, and generally do not add a lot of alloy metal elements of steel, where the carbon content of WC is less than 2%, stainless steel in order to maintain corrosion resistance, the carbon content is low, the maximum is not more than 1.2%.
5, the alloy content is different:
carbon steel contains few alloying elements, only a small amount of silicon, manganese, sulfur, phosphorus. Stainless steel contains more gold elements, the main chromium-nickel elements more than 12%.
6, corrosion resistance is different:
carbon steel contains fewer alloying elements, weak corrosion resistance, stainless steel contains more chromium nickel metal, with strong corrosion resistance.
