In March, the daily output of key iron and steel enterprises decreased on a month on month basis. In terms of enterprise inventory, in late March, the key statistics showed that the 1.8974 steel for large truss truck boom steel inventory of iron and steel enterprises was 18.067 million tons, a decrease of 3.342 million tons or 15.6% compared with the highest inventory in early March, and an increase of 8.534 million tons or 89.5% compared with the beginning of the year.

The alloying principle of low alloy high strength steel is mainly to improve the strength of steel by solid volume strengthening, fine grain strengthening and precipitation strengthening produced by alloy elements. At the same time, the effect of reducing the ductile brittle transition temperature of steel by fine grain strengthening is used to counteract the adverse effect of carbon nitride precipitation strengthening on the rise of ductile brittle transition temperature of steel, so that the 1.8974 steel for large truss truck boom, low alloy high strength steel can obtain high strength while maintaining good low temperature performance.

Hot Rolled Plates Products Testing
BBN STEEL can supply many tests and analysis done to examine them before and after the manufacturing. As the 1.8974 steel for large truss truck boom raw material is fetched by us the steel undergoes vacuum treatment, product analysis, additional tensile test, simulated post weld heat treatment, and impact test. After the steel is converted to steel plates they undergo the drop-weight test, hot tensile test, ultrasonic test, the practical examination through examination, and the vacuum carbon deoxidized steel."
