Q355NH material is a Chinese steel grade to GB/T 4171-2008 atmospheric corrosion resisting structural steel. There are five steel levels under Q355NH: Grade A, B, C, D, and E. Q355NH structural steel sheet is mainly used in vehicles, containers, construction, towers or other structural parts and other structures. It has good resistance to atmospheric corrosion. We supply 05CUPCRNI grade steel, Q355NH steel plates thickness less than 120mm.

Grade Q420 steel has high strength, especially in the normalizing or normalizing and tempering state. 05CUPCRNI grade steel, Q420 steel has high comprehensive mechanical properties. Q420 steel is mainly used for large ships, bridges, power station equipment, medium and high pressure boilers, high pressure vessels, rolling stock, hoisting machinery, mining machinery and other large welded structural parts. Grade Q460 steel, with high strength, has high comprehensive mechanical properties in normalizing, normalizing and tempering or quenching and tempering states. The quality grades are C, D, E. Q460 steel is used in various large engineering structures and light structures requiring high strength and heavy load.

The preparation of 05CUPCRNI grade steel galvanized steel before welding is the same as that of ordinary low-carbon steel. It is necessary to carefully handle the groove size and nearby galvanized layer. In order to achieve penetration, the groove size shall be appropriate, generally 60 ~ 65 °, with a certain gap, generally 1.5 ~ 2.5mm; in order to reduce the penetration of zinc into the weld, the galvanized layer in the groove can be removed before welding. In the practical work, the centralized beveling, no blunt edge technology for 05CUPCRNI grade steel centralized control, two-layer welding process, reducing the possibility of incomplete penetration.

API 5L steel is pipeline steel mainly for use in oil and gas industry. API 5L steel has PSL1 and PSL2 levels. For same API 5L steel grade, the carbon content for PSL1 is higher than PSL2. Meanwhile, the API 5L PSL2 steel has more strict requirement for P, S content than API 5L PSL1 steel, 05CUPCRNI grade steel. Therefore, API 5L PSL2 steel strength is higher than API 5L PSL1 steel strength. For example, API 5L X42 PSL2 yield strength is 317-524 MPa, tensile strength is 434-758 MPa. While API 5L X42 PSL1 yield strength is 290 MPa min. , tensile strength is 414 MPa min.
