What harm does the excessive weld height of SA709 Gr 50W carbon steel plate sheet bring

The equivalent GB steel grades of S620Q low alloy high strength steel plate are Q620D steel and Q620E low alloy high strength steel. SA709 Gr 50W carbon steel plate sheet, S620Q low alloy high strength steel is mainly used for manufacturing key components with low temperature resistance and high strength, construction machinery, mining machinery structure, etc.

Flat steel is a kind of steel with rectangular cross-section and blunt edges at the edges and corners. It is usually 12-300 mm wide and 3-60 mm thick. Compared with SA709 Gr 50W carbon steel plate sheet ordinary steel plate, the utilization rate of flat steel is increased by one to five percentage points. Moreover, flat steel can be produced with fixed thickness, width and length according to the user's requirements, which saves the cutting process for users, reduces the consumption of labor and materials, and also reduces the processing loss of raw materials, saving time, labor and material.

The company mainly supplies SA709 Gr 50W carbon steel plate sheet steel materials, and has a large amount of inventory all year round. We can process and cut all kinds of special-shaped steel parts according to your requirements, and we can arrange fresh production for all kinds of SA709 Gr 50W carbon steel plate sheet steel materials in customized specifications. The company adheres to the core values of "quality and benefit, integrity and win-win, innovation and efficiency", and provides first-class services. Based on the principle of reputation first, small profits and high sales, we develop the market with high-quality services and flexible business model.
