Low alloy steel Q345E angle steel bar can be composed of various stress-bearing components according to the different needs of the structure, and can also be used as a connecting piece between the components. , Q345E angle steel is widely used in various building structures and engineering structures, such as house beams, bridges, power transmission towers, lifting and transportation machinery, ships, industrial furnaces, reaction towers, container racks and warehouse shelves.
Grades NM400 weathering steel, Q345 (16Mn) and Q390 steel have good comprehensive mechanical properties, good welding performance, cold and hot workability and corrosion resistance C, D, E grade steel has good low temperature toughness Mainly used for ships, boilers, pressure vessels, petroleum storage tanks, bridges, power station equipment, lifting and transportation machinery and other higher-load welding structural parts,NM400 weathering steel.
NM400 weathering steel,Quenching is a common heat treatment process. It is the metal heat treatment process in which the metal workpiece is heated to a proper temperature and kept for a period of time, then immersed in the quenching medium for rapid cooling. Quenching can improve the strength and hardness of steel in a large range, and adjust the coordination between strength and hardness, plasticity and toughness. Quenching is generally used as the final heat treatment.NM400 weathering steel
NM400 weathering steel,S355J0 steel density is 7.85g/cm³. S355J0 density represents the mass per unit volume of S355J0 steel, which indirectly affects the price of S355J0 steel. Therefore, the density of S355J0 is also an important consideration for material selection. S355J0 steel tensile strength (σb / MPa):3 NM400 weathering steel,The company's after-sales service tenet is "customer first, timely guarantee, enthusiastic service and effective work".
