ASTM A514 quenched and tempered steel,Low alloy structural steel, also known as ordinary low alloy steel, HSLA steel. , Low alloy steel plates are killed or semi killed steel plates. Low alloy steel plates have the advantages of high strength, better performance, saving material and reducing the weight of structure. The thickness range of low alloy steel plates is usually 4.5-200mm. Low alloy structural steel is mainly used for manufacturing bridges, ships, vehicles, boilers, high pressure vessels, oil and gas pipelines, large steel structures, etc.
Weathering steel is made of ordinary carbon steel with a small amount of copper, nickel and other corrosion-resistant elements. It has the characteristics of high-quality steel, such as strength, toughness, ductility, forming, welding and cutting, abrasion, high temperature, fatigue and so on. The weathering resistance of weathering steel is 2-8 times of that of plain carbon steel , and the coating property is 1.5-10 times of that of plain carbon steel. Weathering steel has the characteristics of rust resistance, corrosion resistance, life extension, thinning and consumption reduction, labor saving and energy saving, etc..ASTM A514 quenched and tempered steel
S355J2 steel plate rolling process is controlled rolling process. In the rolling process, the ingot rolling temperature is 1000-1050℃; in the first stage, the low-speed and large reduction rolling process is adopted, the high-temperature stage is 950-1000℃, the rolling speed is 1.6-2.0m/s, the single reduction rate is 15-20%, and the cumulative reduction rate is 40-45%, so as to ensure sufficient deformation of ingot. In the first stage, the start rolling temperature is 910-930℃, and the finish rolling temperature is ≤ 870℃.
