Hot rolled 12Cr1MoV steel material vs cold rolled 12Cr1MoV steel material

The company is a leading steel production and exporting group in steel materials with advanced production technology, metal-cutting skill, and steel structures engineering projects. We can supply carbon steel plate and sheet, alloy steel plates and structural 12Cr1MoV steel material steel plates. These hot rolled steel plates are sturdy plates having high quality. Their imperviousness to effect and scrapped area, weld capacity, and workability make them a worthy product in a variety of industries.

What is the difference between 20G and 20# steel grade? The difference between 20G and 20# steel is very big. The chemical elements, mechanical properties, service environment and price of 20G and 20# steel are very different. 12Cr1MoV steel material, 20G and 20# steel can not be compared. They are not of the same grade level, and can not be replaced by each other. 20# steel is high quality carbon structural steel, 20G steel is high pressure boiler steel. 12Cr1MoV steel material, 20# steel does not bear pressure, while the use temperature of 20G steel is 450~480℃.

Compared with 12Cr1MoV steel material, pressure vessel and boiler steel plates have such advantages: The pressure vessel and boiler steel should be pure, and the fracture structure of the boiler steel plate should be uniform without cracks and inclusions. Besides, the strain aging sensitivity is small, and the strain aging impact value of the pressure vessel and boiler steel plate is required to be no less than 50% of the non-aging impact value. That is why pressure vessel and boiler steel plate is first choice for fabricating pressure vessels and boilers, while 12Cr1MoV steel material is not.

Quenching and tempering (QT) is a double heat treatment process of quenching and high temperature tempering. In general, medium carbon steel and medium 12Cr1MoV steel material 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 12Cr1MoV steel material 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.
