It not only is high-strength steel, also is low-carbon steel. Q420C low alloy steel has high strength and good fatigue resistance; high toughness and low brittle transition temperature; good cold forming performance and welding performance; good corrosion performance and certain wear resistance. Product specification NM450 plate material range: thickness 8-650mm, width 1500-4020mm, length 3000-18800mmNM450 plate material,Bridge steel is required to have higher strength, toughness, load and impact of rolling stock, and good fatigue resistance, low temperature toughness and atmospheric corrosion resistance With the development of domestic railway construction towards high speed and heavy load, railway bridge steel developing in the direction of high speed, heavy load, long span, beautiful and novel structure, and full welding, higher requirements are imposed on the properties of steel for bridges In particular, the development of cross-sea bridges has put forward higher requirements on the corrosion resistance of steel for bridges,NM450 plate material., S355JR is a European standard low alloy high strength structural steel, which is in accordance with EN10025-2. The hardness of S355JR steel is 70-80B, and the yield strength of S355JR steel is 355MPa. JR stands for quality level, equivalent to level B in ChinaChemical composition of S355JR steel: C: < 0.22; Si: < 0.55; Mn: < 1.60; P: < 0.025; S: < 0.025S355JR steel is equivalent to Q345B in China.In addition to quality assurance, service is also important for the competition of steel suppliers. All the after-sales service personnel of the company have received professional training and assessment. The steel products supplied by our company enjoy the life-long quality problem replacement service. In the process of using our steel NM450 plate material products, if there is any problem, just contact us in time, and our after-sales service personnel will look for countermeasures and solve the problem with you as soon as possible.
