Carbon steel material mainly refers to steel whose mechanical properties depend on the carbon content in the steel, and generally do not add a large amount of alloying elements, sometimes also called plain carbon steel or carbon steel.
Carbon steel materials generally contain a small amount of silicon, manganese, sulfur, and phosphorus in addition to carbon.
Carbon steel materials can be divided into three types: carbon structural steel, carbon tool steel and free-cutting structural steel according to their uses. Carbon structural steel is further divided into two types: architectural structural steel and machine-made structural steel;
According to the smelting method, it can be divided into open hearth steel, converter steel and electric furnace steel;
According to the deoxidation method, it can be divided into boiling steel (F), killed steel (Z), semi-killed steel (b) and special killed steel (TZ);
According to carbon content, carbon steel materials can be divided into low carbon steel (WC ≤ 0.25%), medium carbon steel (WC0.25%-0.6%) and high carbon steel (WC>0.6%);
According to the phosphorus and sulfur content, carbon steel materials can be divided into ordinary carbon steel (higher phosphorus and sulfur), high-quality carbon steel (lower phosphorus and sulfur) and high-quality high-quality steel (lower phosphorus and sulfur). Super high-quality steel.
Generally, the higher the carbon content of carbon steel materials, the greater the hardness and strength, but the lower the plasticity.
(1) Different colors: stainless steel contains more chromium and nickel metals, and its appearance is bright and silvery. Carbon steel is mainly carbon and iron alloy, and other metal elements are relatively small. The main color of the exterior is the color of iron, and the color will be much darker.
(2) Different textures: stainless steel contains more other metal elements and has a smooth surface, while carbon steel contains more iron and carbon, and has the essence of iron, but the surface is not as smooth as stainless steel.
(3) Different magnetism: The surface of carbon steel is magnetized and can be attracted by magnets. Stainless steel has no magnetism under normal conditions and will not be attracted by magnets.
(4) Different carbon elements: Carbon steel mainly refers to the steel whose mechanical properties depend on the carbon content of the steel, and generally do not add a large amount of alloy metal elements. The carbon content WC is less than 2%. In order to maintain corrosion resistance, stainless steel contains carbon. The amount is low, the maximum does not exceed 1.2%.
(5) Different alloy content: Carbon steel contains few alloying elements, only a small amount of silicon, manganese, sulfur, and phosphorus. Stainless steel contains a lot of gold elements, and the main chromium and nickel elements exceed 12%.
(6) Different corrosion resistance: carbon steel contains less alloying elements and has weak corrosion resistance, while stainless steel contains more chromium-nickel metal and has strong corrosion resistance.
