SM490B plate is a kind of structural steel produced according to Japanese Standard JIS G3106. Min. tensile strength of SM490B plate is 490MPa. SM490B plate is mainly used in buildings, bridges, ships, rail vehicles, oil tanks, containers and other buildings requiring high-level weldability. The delivery state is hot rolling for SM490B plate, S355J2W high-speed project steel with thickness less than 80mm; and the delivery state is normalizing for SM490B steel plate with thickness more than 80mm.

A good S355J2W high-speed project steel, automobile steel plate material must have a certain elastic performance, otherwise it will affect the overall comfort performance and aesthetics of the car, especially in the process of driving on some uneven roads. The good quality automobile steel plate can play a certain role in shock absorption, make the driver driving more comfortable. Especially for some drivers with long running length, it can reduce driving fatigue. The high-strength automobile steel plate is stronger in material, and it is more solid and firm when used in the overall frame and other parts of automobile manufacturing, which also improves the quality of the entire automobile.

Laser cutting S355J2W high-speed project steel has no burr, wrinkle and precision is high. It is superior to plasma cutting. Laser cutting has good cutting quality, narrow cutting width (generally 0.1-0.5m m), high accuracy (generally 0.1-0.4mm hole center distance error, 0.1-0.5mm contour dimension error), good surface roughness (generally Ra is 12.5-25μm), and the S355J2W high-speed project steel cutting seam can be welded without further processing. Fast cutting speed: for example, with 2kW laser power, the cutting speed of 8mm thick carbon steel is 1.6m/min.

Mechanical properties of 45# steel high-quality carbon structural steel: Tensile strength σb (MPa): ≥600, yield strength σs (MPa): ≥355, elongation δ5 (%): ≥16, section shrinkage ψ (%): ≥40, impact energy Akv (J): ≥39. 45# steel impact toughness value αkv (J / cm2): ≥49 (5), hardness: unheated, ≤229HB; annealed steel, ≤197HB. S355J2W high-speed project steel, 45# steel chemical composition % (Carbon: 0.42 to 0.50, Silicon: ≤0.40, Manganese: 0.50 to 0.80, Sulfur: ≤0.045, Phosphorus: ≤0.045, Chromium: ≤0.40, Nickel: ≤0.40, Molybdenum: ≤0.10).
