Why B750L structure steel for cold forming quality is so important

For the estimation in April and the second quarter, the estimation on March 16 is still valid, but the decrease in April is 10% higher than the neutral prediction. It is a conservative estimation based on 10% for the high probability event. In the second

For the estimation in April and the second quarter, the estimation on March 16 is still valid, but the decrease in April is 10% higher than the neutral prediction. It is a conservative estimation based on 10% for the high probability event. In the second quarter, the output of overseas pig iron will be reduced by 11.67 million tons, affecting the demand for B750L structure steel for cold forming iron ore of about 1.84 million tons; in the first half of the year, the output will be reduced by 18.899 million tons, affecting the demand for iron ore of 32.13 million tons.

Under the specification EN 10025-2, S275J2 plates are mainly used in the building industry and mechanical engineering, containers,storage tanks and roll formed steel profiles,such as steel angles, steel structures, H-beams, T-sections. For B750L structure steel for cold forming, S275J2 carbon steel, our engineers still suggest done normalized heat treatment for them if customers want to improve their steel's property when using. Else, this steel must be done low temperature impacting test at -20℃.

Heat treatment specification and microstructure of B750L structure steel for cold forming, 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).

The Qatar Railways company launched a tender for designing ,construction and completion of Green Line Project. Our company has participated in the bidding from Qatar Railway Company since May, 2016. A delegation from project visited several famous B750L structure steel for cold forming pipe mill in China for 15 days in July,2016. Of course the delegations had visited our pipe mill.
