Cause of corrosion pits on 09cuptire-a steel grade

Wear Resistant Steel Plate refers to a special plate product designed for use under large-area wear conditions. At present, the commonly used wear-resistant plates are made of ordinary low-carbon steel or low-alloy steel with good toughness and plasticity by surfacing welding with a certain thickness of alloy wear-resistant layer with high hardness and excellent wear resistance. In addition, there are cast wear plates 09CUPTIRE-A steel grade and alloy quenched wear plates.

Just as 09CUPTIRE-A steel grade, the boiler steel plate also has strict control of chemical composition for the material, especially harmful elements such as phosphorus and sulfur, and residual elements such as chromium, nickel, and copper; during smelting, good deoxidation and removal of non-metallic inclusions should be carried out to ensure good quality, plasticity and toughness. The organizational structure requires uniformity, and the grain size is controlled within a certain range; there are also strict requirements for surface quality and internal defects. In addition, the boiler steel plate mechanical properties at room temperature and high temperature must be guaranteed.

Quenching is a heat treatment process in which steel parts are heated to above the critical temperature, and after proper heat preservation, the parts are quickly cooled to room temperature in water or oil, so that martensite transformation occurs. The hardness of the quenched 09CUPTIRE-A steel grade increases sharply. Quenching is to prepare the organization for adjusting and improving the performance of 09CUPTIRE-A steel grade during tempering, while tempering determines the performance and life of the workpiece.

We have huge stocks for carbon steel plates, high strength low alloy steel materials, weather resistant steel sheets, wear resistant steel plates, boiler plates, pipeline steel, etc. Those stocks can be delivered within 10 days after deposit. We update 09CUPTIRE-A steel grade stock list regularly. But the stock changes quickly. It needs to check with warehouse specially when you have urgent needs.
