S690QL brinell hardness made in China

These S690QL brinell hardness products have numerous features like high performance and strength and possess properties that help with welding, fabrication and formability. These steel plates are available from stock; however, all S 460N steel plates can be cut into different shapes, sizes and thickness according to our customer needs. BBNsteel has experience in manufacturing this grade of steel plates which is done according to EN10025-3 standards.

Main uses of S690QL brinell hardness, special steel. First, special steel is used for bearing manufacturing. Second, the special steel is used for mold manufacturing, which can withstand high temperature very well, and has excellent repeated use performance, which makes the mold quality excellent also. Third, the special steel is used in the manufacture of spring plates, and the chassis of some cars need to use the spring plate, which has good elasticity and flexibility. Fourth, the special steel is used in the aerospace industry. Fifth, the special steel is used to manufacture hardware products such as knives and drill bits.

No. 45 steel is commonly used medium carbon quenched and tempered structural steel. The cold plasticity of No. 45 steel is generally better than S690QL brinell hardness. Annealing and normalizing are better than quenching and tempering. No. 45 steel has higher strength and better machinability than Q345 steel. After proper heat treatment, it can obtain certain toughness, plasticity and wear resistance. No. 45 steel S690QL brinell hardness is suitable for hydrogen welding and argon arc welding, but not suitable for gas welding. Preheating is required before welding, and stress relief annealing shall be conducted after welding.
