Chemical composition analysis of SA573 Grade 65 steel shapes, Q690E steel plate: C: no more than 0.2, Si: no more than 0.8, Mn: no more than 1.8, P: no more than 0.02, S: no more than 0.01, Cu: no more than 0.5, Cr: no more than 1.5, Ni: no more than 2, Mo: no more than 0.7, B: no more than 0.005.
The company formulates appropriate SA573 Grade 65 steel shapes product internal control components, strictly controls the fluctuation range of chemical components, and ensures the stability of steel plate performance. Strengthen batching control and smelting operations, effectively control the content of harmful elements such as Sn, Sb, As, Cu, and reduce the content of P and S to improve the purity of steel, reduce the tendency of temper embrittlement, and improve the high temperature corrosion resistance of steel. It adopts controlled heating to ensure heating time and temperature, and measures such as controlled rolling to ensure the inherent quality of the steel plate.
Compared with other fast-moving consumer goods, steel consumption is obviously different, with a wide range of use and a long service life. Therefore, the quality and service of steel materials are particularly important. Service is always one of our top concerns, especially after-sales service. We have mature after-sales service team, and can help you solve problems professionally during application of the steel materials.
