What is the S235J0W steel structure price export to Australia

Our company's S235J0W steel structure power boilers, heating furnaces of double bars, double high lines and medium and thick plates all adopt heat storage technology, which can fully use blast furnace gas; the ladle baking, Maerz active lime kiln and medium and thick plate heat treatment furnace all burn converter gas, which can improve the S235J0W steel structure utilization rate of secondary energy and realize negative energy steelmaking in steelmaking process.

Is carbon steel 20#? Carbon steel means that alloy elements are not specially added into the steel, which is divided into ordinary carbon structural steel and high-quality carbon structural steel. The grades of ordinary carbon structural steel are Q195, Q215, Q235 and Q275. The grades of high quality carbon structural steels are: 10#, 20#, 45#, 15Mn, 20Mn, 25Mn, 30Mn, 35Mn, 40Mn, 45Mn, 65Mn, etc. It can be seen that S235J0W steel structure, 20# steel is carbon steel, but carbon steel means more than 20# steel.

40Cr steel belongs to alloy structural steel. S235J0W steel structure, 40Cr steel has good comprehensive properties, low temperature impact toughness and low notch sensitivity after quenching and tempering on the basis of high-quality carbon structural steel No. 40. 40Cr steel mechanical properties: tensile strength: ≥ 980mpa, yield strength: ≥ 785MPa, elongation after fracture: ≥ 9%, elongation after fracture: ≥ 45%, impact absorption energy: ≥ 47J. 40Cr steel chemical composition: C: 0.37-0.44, Si: 0.17-0.37, Mn: 0.50-0.80, Cr: 0.80-1.10.

The characteristic of niobium in S235J0W steel structure etc. steel material is to increase the recrystallization temperature of austenite, so as to achieve the purpose of refining austenite grains. In general, the amount of niobium added in steel material is less than 0.05%, and the contribution of niobium above 0.05% to strengthening and toughening will no longer be obvious.

Heat treatment specification and microstructure of S235J0W steel structure, 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).
