Five causes of cracks in GL-A hot-rolled steel strip during quenching

When talking about our team, it is hard not to mention our QC department (Quality Control). We have built strict qualitycontrol system to guarantee the steel quality. During the steel materials production, we have strict monitoring measures and indicators, and ensure no chemical composition, mechnical properties and so on technical problems for the steel materials GL-A hot-rolled steel strip. After production, our QC department will conduct another inspection regarding to the steel quantity, dimension, mark and so on points before delivery.

GL-A hot-rolled steel strip, 09CrCuSb steel has the following advantages: 1. The alloy ratio is optimized and rare alloy is added. The finished steel product has excellent sulfuric acid uniform corrosion resistance. 2. The content of As, Sn, Pb and other elements, and the gas content of hydrogen, oxygen and nitrogen are controlled to improve the purity of the billet. According to the analysis of many times, the grain size of the material is not coarser than grade 6. The corrosion resistance of the equipment made of 09CrCuSb steel is improved, and the maintenance cycle is relatively prolonged, which has great economic benefits.
