Sulfur is a very harmful element in S960Q material steel. The presence of sulfur will increase the hot brittleness of steel, reduce the various mechanical properties of S960Q material steel, and reduce the weldability, impact toughness, fatigue resistance and corrosion resistance of steel.
Q460D material is a low-alloy ultra-high-strength steel with high hardenability. The critical hardening diameter in oil is 60mm (96% martensite). The steel can obtain high strength after quenching and tempering. The toughness, and can be processed into shape; but the cold deformation plasticity and weldability are low.
In February, the European steel price index was 161.2 points, up 1.3 points on a month on month basis, up 0.8%; the euro zone manufacturing PMI was 49.2%, up 1.3 percentage points on a month on month basis. The manufacturing PMI of Germany, Italy, France and Spain were 48%, 48.7%, 49.8% and 50.4% respectively. This month, among the main steel products such as S960Q material in the German market, the price of wire rod decreased slightly, the price of section steel remained stable, and other products continued to rise.
