Material NM450 steel grade with 320007000mm size

ST52 steel angle steel with carbon content of 0.23% and yield point strength of 355 MPa is suitable for weldable and supporting members. In terms of chemical composition and mechanical properties, s355n is similar to NM450 steel grade en10025 - 3. Compared with ASTM A36, ST52 has higher strength and better welding performance. It is also used in daily life and industrial applications such as warehouses, equipment, etc. Note: although similar NM450 steel grade properties are shared, they are a little different. Please let us know your detailed requirements and we will tell you the most suitable steel grade.

NM450 steel grade, 20CrMo alloy steel plate has high hardenability, no temper brittleness, good weldability, little tendency of cold cracking, good machinability and cold strain plasticity. 20CrMo alloy steel plate is generally used in the state of quenching and tempering or carburizing and quenching. 20CrMo alloy steel plate is used to manufacture high-pressure pipes, fasteners and carburized parts, such as gears and shafts, working in non corrosive medium and medium containing mixture of nitrogen and hydrogen under 250 ℃.

The preparation of NM450 steel grade 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 NM450 steel grade centralized control, two-layer welding process, reducing the possibility of incomplete penetration.
