Product Description

Product Description

Low alloy high strength steel is a kind of engineering structural steel developed by adding a small amount of Mn, Si, Nb, V, Ti, Al and other alloy elements on the basis of carbon structural steel. The so-called low alloy means that the total amount of alloy elements in steel does not exceed 3%. High strength is relative to carbon engineering structural steel. The development principle of low alloy high strength steel is to use as few alloying elements as possible to obtain as high comprehensive mechanical properties as possible, so as to meet the purpose of use and low cost. Low alloy high-strength steel can meet the requirements of large bearing capacity of various structures (such as large bridges, pressure vessels, ships, etc.) in engineering, and at the same time, it is required to reduce the dead weight of structures, improve reliability, and save materials and resources. This kind of steel is mainly used to manufacture various engineering structures with high strength requirements, such as bridges, ships, vehicles, high pressure vessels, oil and gas pipelines, large steel structures, etc. Because this kind of steel can obtain high strength without complex treatment process or even heat treatment, which greatly reduces the quality of engineering structures, it is used to replace general carbon structural steel.

Features and applications

The strength and hardenability of steel are higher than that of 15 steel. After carburizing, it can be directly quenched. The carburized layer has high surface hardness and wear resistance, but it has large deformation during heat treatment, temper brittleness, high cold deformation plasticity, good weldability, and good machinability after annealing. It is generally used as carburizing steel and also as low carbon martensitic steel. It is mainly used to manufacture parts with high working speed, small cross section but high requirements for strength and toughness in the center, and surfaces subject to wear, such as gears, cams, slide valves, pistons, bushing crank pins, piston ring couplings, shafts, bearing rings, etc. It can also be used as low-carbon martensite quenched steel to manufacture parts that do not have strict requirements for deformation but require strength and toughness
