S690QL1 ASTM equivalent as customers request

Austenitic stainless steel has good plasticity and low strength, but its corrosion resistance is the best among the stainless steels. S690QL1 ASTM equivalent, Austenitic stainless steel is suitable for the occasions where the mechanical properties are not required to be very high, such as chemical plants, chemical fertilizer plants, sulfuric acid and hydrochloric acid manufacturers, etc. Of course, austenitic stainless steel can also be used in submarine and other military industries.

40Cr steel belongs to alloy structural steel. S690QL1 ASTM equivalent, 40Cr steel has good comprehensive properties, low temperature impact toughness and low notch sensitivity after quenching and tempering on the basis of high-quality carbon structural steel No. 40. 40Cr steel mechanical properties: tensile strength: ≥ 980mpa, yield strength: ≥ 785MPa, elongation after fracture: ≥ 9%, elongation after fracture: ≥ 45%, impact absorption energy: ≥ 47J. 40Cr steel chemical composition: C: 0.37-0.44, Si: 0.17-0.37, Mn: 0.50-0.80, Cr: 0.80-1.10.

Steel production and rolling technology and equipment also pursue the continuity between processes, such as the continuous S690QL1 ASTM equivalent process between continuous casting and rolling mills, continuous casting slabs hot transfer hot charging, increased direct rolling, and continuous cold rolling processes. The development of controlled rolling and controlled cooling technology that combines rolling and heat treatment has played a huge role in improving the properties of rolled materials.

The company will rely on its good reputation, excellent hot-rolled plates, steel pipes, steel structure products, and intimate S690QL1 ASTM equivalent after-sales service to customers. I would like to express my heartfelt thanks to the old and new friends and customers who have always given care, support and help to the company! The company sincerely hopes to establish a long-term cooperative relationship with them, mutual benefit and common development. Welcome to come and visit our S690QL1 ASTM equivalent steel mill.

Before delivering our hot rolled plate product we apply various tests to check the quality of carbon steel S690QL1 ASTM equivalent plates such as- mechanical test, chemical test, hardness test, toughness test, eddy current test, impact test, micro test, flaring test, flattening test, etc. We are provided best packing for structural steel plates to avoid rust. Our after-sales service team will contact you if you have any question.
