EN 10025 S690Q high strength steel 6' x 20' x 21mm thick MS plate

35CrMoA steel has high static strength, impact toughness and higher fatigue limit, higher hardenability than 40Cr, high creep strength and endurance strength at high temperature, long-term working temperature can reach 500℃; plasticity during cold deformation Medium, poor weldability. Alloy steel EN 10025 S690Q high strength steel is used as important structural parts that work under high loads, such as transmission parts of vehicles and engines; rotors, main shafts, heavy-load transmission shafts of steam turbine generators, and large-section parts.

The thermal conductivity of NM360 wear-resistant plates is only 1/2 of that of carbon steel, EN 10025 S690Q high strength steel, and even in the high temperature stage of 900-1000℃, the thermal conductivity is lower than that of carbon steel at the same temperature. Therefore, the heating rate of the NM360 wear-resistant plate, especially in the low temperature stage, should be lower than that of carbon steel to avoid excessively steep internal temperature gradients and cracks.

Flame cutting is a common hot cutting method in modern iron and steel industry. It is also a very important part in the process of iron and EN 10025 S690Q high strength steel steel processing. Flame cutting can cut very thick carbon steel, its cutting range is very wide, can cut 6mm-200mm thick steel plate. In cutting thick and EN 10025 S690Q high strength steel medium plates, flame cutting plays an important role. And with its price advantage, flame cutting has always occupied a certain market share in thin plate cutting also.
