nm550 steel wear resistance carbon metal

SAE4340, same as UNS G43400. Tensile strength σb ≥980(100) Yield strength σs ≥835(85), used to manufacture important parts with high strength and good plasticity. After nitriding treatment, make important parts with special functional requirements, such as shafts, gears, and gears. Firmware etc. Delivery NM550 steel wear resistance in heat treatment (normalizing, annealing or high temperature tempering) or without heat treatment.

Boiler steel plates for room temperature and medium temperature (below creep temperature) are mostly carbon steel, including carbon steel, carbon manganese steel, carbon manganese silicon steel, NM550 steel wear resistance, etc. They are mainly used in the manufacture of pressure-bearing parts such as boiler drums and header end covers below medium temperature. High temperature (above creep temperature) boiler steel plates are mainly used to manufacture high-temperature pressure-bearing parts such as high-temperature header end caps and steam pipe blocking plates.

Nickel element is mainly used to form and stabilize the austenite structure, so that the NM550 steel wear resistance steel has good mechanical properties, corrosion resistance and process performance. Molybdenum can quickly passivate stainless acid-resistant steel, and improve the corrosion resistance to solutions containing chloride ions and other non-oxidizing media. Titanium and niobium are usually used to fix the carbon in alloy steel and make it generate stable carbides to reduce the harmful effect of carbon on the corrosion resistance of alloy steel.
