09CuPCrNi-A is a high-strength weathering steel. Among them, the combination of Cu and P can resist atmospheric corrosion. In addition, there are Cr and Ni, both of which are used in stainless steel. Weathering steel (that is, atmospheric corrosion resistant steel) is a series of low-alloy steels between ordinary steel and stainless steel at a low price and good quality. After incorporating modern metallurgical new mechanisms, new technologies and new processes, it can achieve sustainable development and innovation.
Over the years, the company has established a standard of A572 grade 42 CS steel carbon plate steel products pre-sale, in sale and after-sale service, which meets customers' needs in all aspects and in the whole process, so that our products and services are deeply trusted by customers, and has established a long-term cooperation and mutual benefit relationship with customers. The company adheres to A572 grade 42 CS steel carbon plate quality surpervision, comprehensively implements quality management, strictly controls the whole process of product from contract signing to after-sales service.
The advantage of hot-rolled stainless steel plate is that it can eliminate the damage caused by A572 grade 42 CS steel carbon plate metal structure in the process of ingot casting to a certain extent, eliminate some tiny defects in the structure, refine the grains of stainless steel material, promote the structure of steel closer, and improve the performance of the material as a whole. This kind of lifting is mainly manifested in the rolling direction, which can make the A572 grade 42 CS steel carbon plate steel no longer isotropic to some extent, and some defects such as bubbles, cracks and looseness formed during pouring can be eliminated under high temperature or high pressure.
The strengthening mechanisms in metals mainly include solid solution strengthening, dislocation strengthening, fine grain strengthening, and second phase (precipitation and dispersion) strengthening. Alloying elements have the most significant strengthening effect on steel in the quenched and tempered state, because it makes full use of all four strengthening mechanisms. Martensite is formed during quenching, and carbides are precipitated during tempering, resulting in a strong second phase strengthening and greatly improving toughness. Therefore, obtaining martensite and tempering it is the most economical and effective comprehensive strengthening method for A572 grade 42 CS steel carbon plate.
Before delivering our hot rolled plate product we apply various tests to check the quality of carbon steel A572 grade 42 CS steel carbon plate 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.
