Carbon steel S690QL1 1.8988 high strength steel coil ms mild steel price

30CrMnTi steel has higher strength and hardenability than 20CrMnTi steel, but its impact toughness is slightly lower. Mainly used as carburizing steel, it can be quenched directly after carburizing, with high bending strength and good wear resistance. It can be used after quenching, low temperature tempering or quenching and tempering, with medium machinability. 30CrMnTi steel can be used in the manufacture of heavy-duty carburized parts with large cross-sections and gears, gear shafts, worms, etc. with large forces in the tractor industry.

Weathering steel plate for welding structure is made by adding metal materials such as chromium, molybdenum, titanium and vanadium to ordinary molten steel. The addition of these materials can form a protective film on the steel surface, which can resist weathering corrosion for a long time. The advantages of weathering steel plate for welding structure: It has very good welding performance and weather resistance, and is widely used in railways, bridges and other areas that need to be exposed to the atmosphere for a long time. Disadvantages of weathering steel plate for welded structure: It has very high requirements on the production process, and the poorer technology can not produce good weathering steel plate, S690QL1 1.8988 high strength steel coil.

Tempering the important S690QL1 1.8988 high strength steel coil welding structure often use high temperature tempering to remove residual weld stress. Classification: high temperature tempering above 400 ℃, medium temperature tempering 250 ~ 400 ℃, low temperature tempering 150 ~ 250 ℃, Quenching +Tempering is improve S690QL1 1.8988 high strength steel coil strength, plasticity and toughness.
