S960QL steel plate metal sheets made in China

Steel is an alloy of iron with carbon, silicon, manganese, phosphorus, sulfur and a small amount of other elements. In addition to iron, carbon content plays an important role in the mechanical properties of S960QL steel plate and so on steel. Iron and steel is an important raw material for machinery, construction, hardware and other industries. As an important pillar industry, the development of iron and steel has a glorious period, in which Tangshan was once an important production base of China's iron and steel. This is closely related to its geographical location and energy advantages.

EN10113 S275M is a technical delivery conditions for thermomechanical rolled weldable fine grain structural steels.S means the structural steel, M means the delivery condition.The EN10113 S275M steel is equivalent to DIN StE285TM, UNI FeE275KGTM. EN10113 S275M steel plate/sheet, EN10113 S275M steel plate/sheet, under EN standard, we can regard S960QL steel plate, S275M steel plate/sheet for Fine-grain structural steels, thermomechanically rolled steel.

Vanadium mainly exists in the form of carbide in S960QL steel plate and so on steel. Its main function is to refine the structure and grain size of steel and reduce the strength and toughness of steel. When the solid solution is dissolved at high temperature, the hardenability is increased; conversely, if it is in the form of carbide, the hardenability is reduced. Vanadium increases the tempering stability of quenched steel and produces secondary hardening effect. The vanadium content in steel, except high speed tool steel, is generally less than 0.5%.
