Key smelting points to ensure the successful production of S690QL steel hardness

ASTM A633 standard covers four grades A, C, D, and E normalized high-strength low-alloy structural steel plates for welded, riveted, or bolted construction. S690QL steel hardness, A633 Grade A structural steel provides a minimum yield point of 42 ksi [290 MPa] in thicknesses through 4 in. [100 mm], inclusive. Grades C and D provide a minimum yield point of 50 ksi [345 MPa] in thicknesses up to 2.50 in. [65 mm], inclusive and 46.0 ksi [315 MPa] in thicknesses over 2.50 in. to 4.0 in. [65 to 100 mm], inclusive.

Although S690QL steel hardness, low carbon steel has excellent plasticity, toughness and processing technology, its strength is low and its corrosion resistance is not strong enough. On the basis of ordinary low carbon steel, the low alloy structural steel with high strength, high toughness, good weldability and corrosion resistance can be obtained by adding a small amount of alloy elements and the total amount is less than 3%. Manganese is the main additive element in this kind of steel, and its content is about 1% ~ 1.6%.

Provide special product requirements to meet the personalized needs of customers. The S690QL steel hardness company arranges production and shipment strictly according to the contract, and guarantees to supply goods according to the time agreed in the contract. Provide professional consultation: we guarantee to answer any professional and S690QL steel hardness technical questions raised by users within 1 hour; provide detailed information.
