In recent years, in line with the development trend of iron and a572 vs a656 steel industry at home and abroad, we have accelerated the transformation of development mode, promoted structural adjustment, and formed a rich product series of medium and thick plates, hot rolled steel coils, profiles, steel pipes, etc., which a572 vs a656 are widely used in automobiles, long-span bridges, railways, machinery, ocean and so on fields. Meanwhile, we also provide deep processing for the steel materials.
Q690C steel plates are mainly used in heavy machinery, marine engineering, metal structures. BBN STEEL cooperated with Wugang to produce Q690C steel for use in its enterprise production and construction projects. The prospects for produts exporting to the United States, Canada, Australia, India, and Europe are promising. More than 10,000 tons a572 vs a656 products have been directly supplied to European customers.
Generally, the steel plates for boiler and pressure are divided into categories. A516 gr60 carbon steel plates have a maximum thickness that varies on the capacity. The tensile strength, elongation, yield strength, and hardness are the mechanical properties of these plates. Physical and chemical characteristics of the boiler quality plates a572 vs a656 make these a popular choice in the industries. Also, these carbon steel are made up of premium quality raw materials by the use of the latest machinery and are therefore of robust built.
With the increase of temperature, the yield limit of a572 vs a656 will decrease monotonically, but the tensile strength of a572 vs a656 will rise to a high peak value at a certain temperature, and then decrease. This peak temperature is called the blue brittleness temperature of a572 vs a656. Near the blue brittleness temperature, the a572 vs a656 strength increases and the plasticity decreases. The elongation and section shrinkage of a572 vs a656 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.
Heat treatment specification and microstructure of a572 vs a656, 12Cr1MoV alloy plate:Heat treatment specification: quenching 970 ℃, air cooling; tempering 750 ℃, air cooling. Microstructure: bainite + ferrite.Mechanical properties of 12Cr1MoV alloy plate:Tensile strength σb (MPa)：≥490(50); Yield strength σs (MPa)：≥245(25); Elongation δ5 (％)：≥22; area shrinkage ψ (%): ≥ 50; Impact energy Akv (J): ≥ 71; Impact toughness value αkv (J/cm2)：≥88(9).
