The difference between Q235 steel and Q345 steel:The lower limit of yield strength of Q235 steel is 235MPa, the lower limit of yield strength of Q345 steel is 345MPa. The NM450 steel yield strength alloy content of Q235 steel is common carbon steel and Q345 steel is low alloy steel. Q345 steel is used for structures, mechanical parts, building structures, general metal structures bearing dynamic loads such as medium and low pressure vessels, oil tanks, vehicles, cranes, NM450 steel yield strength mining machinery, power stations, bridges, etc..

NM450 steel yield strength, 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.

Grade Q420 steel has high strength, especially in the normalizing or normalizing and tempering state. NM450 steel yield strength, 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.
