Why sa573 grade 70 structural quality carbon steel plate is generally not heat treated

The company has a group of mature steel plate production and processing line construction and production management experience. In addition, the company has professional and technical personnel. BBN steel is a modern enterprise integrating scientific research and development, production processing, sales and service. The company now has finance department, production department, sales team, technical department, quality control department, logistics department and after-sales service team. At the same time, it also adheres to international standards and adheres to the international line.

Wear resistant steel plate has high wear resistance:
The thickness of wear-resistant layer of wear-resistant steel plate is 3-12mm, the hardness of wear-resistant layer can reach HRC58-62, the wear resistance is 15-20 times of ordinary steel plate, 5-10 times of low-alloy steel plate, sa573 grade 70 structural quality carbon steel plate, and 2-5 times of high chromium cast iron. The wear resistance is far higher than spray welding and thermal spraying.

P235GH steel material number under EN10028-2:2003 standard is 1.0345. This steel is a European pressure vessel steel. P235GH Mechanical properties: Tensile strength σb (350 ~ 480 MPa); Yield strength σs(215 MPa min.); Elongation ≥25%; Brinell hardness ≤105 ~ 140. sa573 grade 70 structural quality carbon steel plate, P235GH steel chemical composition (mass fraction,%): ≤0.16 C; ≤0.35 Si; 0.60 ~ 1.20 Mn; ≤0.025 P; ≤0.010 S; ≤0.30 Cr; ≤0.30 Ni; ≤0.30 Cu; ≤0.08 Mo; ≤0.02 V; ≤0.02 Nb; ≤0.012 N; ≤0.020 Al; ≤0.03 Ti.

When providing technical services on site, the after-sales personnel shall strictly abide by the safety rules and regulations of the construction site, consciously take safety protection measures (such as wearing safety helmet when entering the construction site), accept the supervision and management of the site; without permission on the construction site, they shall not dismantle, smear or damage any goods; the commissioning of contract goods shall be carried out under the supervision of the site supervisor If necessary, it shall be approved by the site supervisor or the person in charge of the project department.
