Hot rolled JIS SM400C plates yield strength value

The toughness of steel such as JIS SM400C plates is the ability of steel to absorb energy in the process of plastic deformation and fracture, and also the ability of steel to resist impact load. It is related to and different from the plasticity of steel. It is the comprehensive performance of strength and plasticity. The strength plasticity index of steel is obtained by static tensile test. When these indexes are used to bear the dynamic load structure, there are obvious limitations.

Q420B material is a low-alloy high-strength structural steel. JIS SM400C plates, Q420 is not high-strength steel, it is still low-carbon steel. Its tensile strength has been improved a bit. The tensile strength of Q235 steel is 235MPa, and the tensile strength of Q420B steel is 420MPa. Q420B low alloy steel has high strength and good fatigue resistance; high toughness and low brittle transition temperature; good Cold forming performance and welding performance; has good corrosion resistance and certain wear resistance.

BEBON Iron & Steel has fully passed the ISO9001 quality system certification, marine steel has passed 9 countries' classification societies, and construction steel has obtained the CE Lloyd's CE Mark certification. The main body of JIS SM400C plates steel passed ISO14001 environmental management system certification and OHSAS18001 occupational health and safety management system certification. The main JIS SM400C plates production processes and technical equipment of the enterprise have reached the international advanced level, the comprehensive competitiveness has entered the international advanced ranks, and the international influence has been significantly enhanced.

Hot-rolled coil is a commonly used steel product in the industry. It has a relatively wide variety of products and a wide range of uses. JIS SM400C plates, Hot-rolled coils are widely used in related industries such as petrochemical equipment, automobiles and bridges. Hot-rolled coils are also used in machinery industries such as ships and automobiles because of their good toughness and relatively high strength.
