equivalent grades of nm450 steel structural steel pipe

Every customer who has visit us and witness the steel materials before delievry will be impressed by our quality control departemnt. Even not come to inspect the steel materials before delievry, our quality control departemnt will also send inspection report to the customer. For each order, no matter its quantity and value, our quality control departemnt will make strict inspection before delivery, the inspection contents include apperance, tolerance, dimension, mark, special requirements of customers, etc. To guarantee our steel materials sent to the customer is qualified.

Structural steel S355JR, S355J0, S355J2G, S355J2G4 are low-alloy high-strength structural steels that comply with the European standard EN10025. S355JR steel in China is a low-alloy high-strength structural steel with a hardness of 70-80B and a yield strength of 300-400MPa. S355J2G3 steel is roughly equivalent to GB Q345D. S355J2G3 means that the delivery state is normalized, and the impact energy at -20°C is 27J. G3 and G4 mean the deoxidation method.

equivalent grades of NM450 steel, HP265 steel with the thickness range is 1.2-12mm. HP265 steel’s mechanical properties is include the yield strength more than 265MPa, tensile strength is 410-520MPa. The chemical composition of HP265 steel is C element content is 0.18, the Si element content is 0.10, the Mn element content is 0.80, the P element content is 0.025% max, the S element content is 0.015% max.

The surface quality of pickling coil is very good. Compared with ordinary hot-rolled plate, equivalent grades of NM450 steel, the surface quality of hot-rolled pickling coil is improved in addition to the oxide scale on the surface, which is convenient for welding, oiling and painting. The accuracy of pickling coil specification is high. After leveling, the shape of the plate changes to a certain extent, thus reducing the deviation of unevenness, improving the surface finish and enhancing the appearance effect of pickling coil.

Both parties shall confirm the equivalent grades of NM450 steel material object and the quality of the products, confirm the reasons for the defects and the quality of the products, and sign the quality inspection agreement. Major quality objections shall be reported to relevant leaders in a timely manner, and shall be discussed and solved with the equivalent grades of NM450 steel steel plant.
