Our company will appoint a full-time service manager to be responsible for the unified coordination of technical support and A573 Gr.70 steel vs Q390C steel plate after-sales service of the project.

The difference between alloy steel plate and carbon steel has the following points. First, the hardenability of carbon steel is low, and the maximum diameter of water quenching of carbon steel is only 10 mm to 20 mm; second, the strength of carbon steel is only 235 MPa, while that of alloy steel is more than 360 MPa. Third, carbon steel has poor tempering stability. In order to ensure high strength, low tempering is used for carbon steel during quenching and tempering treatment, so the toughness of the carbon steel is insufficient. Fourth, the corrosion resistance, low heat resistance, and wear resistance of carbon steel cannot be compared with alloy steel, A573 Gr.70 steel vs Q390C steel plate.

Quenching and tempering (QT) is a double heat treatment process of quenching and high temperature tempering. In general, medium carbon steel and medium A573 Gr.70 steel vs Q390C steel plate carbon alloy steel often need quenching and tempering treatment. Quenching and tempering can make iron and steel parts obtain a good combination of strength and toughness, with high strength, excellent toughness, plasticity, cutting performance, etc. Some A573 Gr.70 steel vs Q390C steel plate alloy steel or low alloy steel must be quenched and tempered to obtain good comprehensive properties. These steels can also be called quenched and tempered steels.

EN10025-6 S960QL structural steel plates are quenched and tempered high strength steel with yield strength of 590Mpa ~ 960MPa. A573 Gr.70 steel vs Q390C steel plate, S960QL steel plates have technical requirement of flaw detection, Z15 Z35 thickness direction performance requirements, high strength and high toughness requirements and so on.
