Wear-resistant alloy steel means that in addition to steel containing silicon and manganese as alloying or deoxidizing elements, it also contains other alloying elements (such as chromium, nickel, molybdenum, vanadium, titanium, copper, tungsten, aluminum, cobalt, niobium, zirconium and other elements) and some non-metallic elements (such as boron, nitrogen, etc.), depending on the content of alloying elements in steel.

Carbon steel is mainly determined by the carbon content of steel mechanical properties, and generally do not add a large number of alloying elements of steel, also known as ordinary carbon steel or carbon steel.

Carbon steel, also known as carbon steel, is an iron-carbon alloy with a carbon content of less than 2% WC. Carbon steel generally contains a small amount of silicon, manganese, sulfur, phosphorus and other elements in addition to carbon. According to different uses, carbon steel can be divided into carbon structural steel, carbon tool steel and structural steel that is easy to cut. Carbon structural steel is divided into structural steel for construction and structural steel for mechanical manufacturing. Carbon steel can be divided into carbon steel (WC 0.25%), medium carbon steel (WC 0.25-0.6%) and high carbon steel (WC greater than 0%). 6%) according to the content of phosphorus and sulfur, carbon steel can be divided into ordinary carbon steel (high phosphorus and sulfur), high quality carbon steel (low phosphorus and sulfur) and high quality steel (low phosphorus and sulfur).

Wear-resistant alloy steel is generally based on the total amount of alloying elements.

Low alloy steel (WME lt5%), polymeric diamond (wMe = 5% ~ 10%) and high alloy steel (WME gt is 10%).

According to the type of alloy elements, alloy steel is divided:

Chromium, manganese steel, silicon, chromium, nickel, etc.

According to the use, wear-resistant alloy steel is divided:

Structural steel, tool steel, Nantong stainless steel processing, heat-resistant steel, etc.

Typical steel grades and uses.

CrMn, GCr15, CrWMn are used in the manufacture of calipers, spiral microns, block gauges, plug gauges, etc.

Special performance of wear-resistant alloy steel according to the use of stainless steel, wear-resistant steel, heat-resistant steel, acid-resistant steel and so on. Here mainly introduces stainless steel, stainless steel is divided into martensitic stainless steel, ferritic stainless steel, austenitic stainless steel. The low carbon in the stainless steel composition is less than 0.4%, and the lower the carbon, the higher the corrosion resistance. An important alloying element Cr is added. Nb, Mo, Ti, Ni, Mn and the like are added.

Composition characteristics, carbon content 0.1~0.4, Cr content 13%;

Typical steel grades and uses. 1Cr13 and 2Cr13 are mainly used for blades, hydraulic valves, bolts and nuts. 3Cr13 and 4Cr13 are mainly used for making medical tools.
