Alloy steel SMA490AW, SMA490BW, SMA490CW steel grades to manufacture steel pipes

34CrMo4 Alloy steel, we can supply the round bar, steel flat bar, plate, hexagonal steel bar and SMA490AW, SMA490BW, SMA490CW steel grades steel square block. steel Round bar can be sawn to your required lengths as one offs or multiple cut pieces. 34CrMo4 alloy steel Rectangular pieces can be sawn from flat bar or plate to your specific sizes. Ground tool steel bar SMA490AW, SMA490BW, SMA490CW steel grades can be supplied, providing a quality precision finished bar to tight tolerances.

The steel plates for SA302GrC boilers must withstand different pressures and strengths due to the manufactured containers. Generally, the normal pressure is 314MPa or higher, and the working temperature is often between -20°C and 450°C. According to the working conditions and processing requirements of the vessel, the steel plate must have good cold bending and welding performance, good plasticity and toughness, and high temperature short-term strength or long-term strength performance.

Low-alloy steel plates have low carbon content, and because ferrosilicon is not used for deoxidation, the silicon content in steel is often <0.07%. The outer layer of rimmed steel is crystallized in a rimmed state, so the surface layer is pure and dense, the surface quality is good, and the Zhengzhou low alloy steel plate SMA490AW, SMA490BW, SMA490CW steel grades has good processing performance. Rimmed steel does not have large concentrated shrinkage cavities, uses less deoxidizer, and the cost of steel is low.

With the increase of temperature, the yield limit of SMA490AW, SMA490BW, SMA490CW steel grades will decrease monotonically, but the tensile strength of SMA490AW, SMA490BW, SMA490CW steel grades will rise to a high peak value at a certain temperature, and then decrease. This peak temperature is called the blue brittleness temperature of SMA490AW, SMA490BW, SMA490CW steel grades. Near the blue brittleness temperature, the SMA490AW, SMA490BW, SMA490CW steel grades strength increases and the plasticity decreases. The elongation and section shrinkage of SMA490AW, SMA490BW, SMA490CW steel grades increase with the increase of temperature, but there is a low peak at the blue brittleness temperature. The blue brittleness temperature of low carbon steel ranges from 200 ℃ to 250 ℃. The blue brittleness of low alloy steel is not obvious as that of low carbon steel, and the blue brittleness temperature is higher.
