ST37-2 is a kind of low carbon steel with carbon content of 0.20%, similar to S235JR or Q235 A514 Gr Q quenched and tempered steel. It's not as strong as common ASTM A36, but it is also widely applied by everyday uses and structural applications where high strength is not so important. Equal ST37-2 angle steel size: A514 Gr Q quenched and tempered steel Size: 20 × 20 mm to 200 × 200 mm. Thickness: 3 - 35 mm. Length: 6 m, 9 m or as required. Unequal ST37-2 angle steel size: A514 Gr Q quenched and tempered steel Size: 30 × 20 mm to 250 × 90 mm. Thickness: 3 to 10 mm. Length: 6 m, 9 m, 12 m or per your request.
How to prevent A514 Gr Q quenched and tempered steel, steel plate cutting cracks? 1. Preheat the steel plate before cutting, and the preheating temperature depends on the quality grade and thickness of the steel plate. However, it needs to be heated evenly. 2. The cutting speed is reduced appropriately, but its reliability is not as good as preheating. It is suggested to preheat the cutting belt with flame gun cavitation several times before cutting, and the preheating temperature should reach about 180℃.
The difference between cold rolled steel sheet and hot rolled steel plate. The carbon content of A514 Gr Q quenched and tempered steel, hot rolled steel plate is slightly higher than that of cold rolled steel sheet. In the case of little difference in composition, the density of cold rolled steel sheet and hot rolled steel plate is the same. Hot rolled steel plate has characteristics of low hardness, easy processing and good ductility. Cold rolled steel sheet has high hardness, and it is relatively difficult for processing. But it is not easy to deform and has high strength. Hot rolled steel plate can be made into alloy steel plate by adding other elements, and its properties are also excellent compared with other high-quality steel plates.
