Customers are satisfied with the quality of A588GrA weathering steel plate

A588GrA is an American standard weathering steel, which also has good weather resistance and excellent toughness, welding and other performance, and has a broad market prospect. In order to further optimize the variety structure and improve the market competitiveness of enterprises, our company has carried out the research and development of A588GrA weathering high-strength structural steel plate , to create conditions for the realization of mass production.

The A588GrA weathering steel plate produced in this trial are all used for export, and the customers have responded well, and they are fully capable of mass-producing weathering steel sheets.

The composition design of the A588GrA weathering steel plate developed and trial-produced is reasonable, and the compositional fluctuation of Cu, Cr, Ni, v and other weathering elements in the billet is gentle and the billet composition is uniform and the quality is stable.

The A588GrA weathering steel plate has good surface quality, uniform internal structure and grade 9 grain size. Through the control of key processes such as continuous casting secondary cooling and steel rolling cooling, "Cu hot cracking" has been effectively controlled.

The statistical results show that the minimum yield strength of the A588GrA weathering steel plate produced in trial production is 355 MPa, which is 40 MPa higher than the standard value; the elongation after fracture is more than 23%, and the user's response is good, and the mass production of A588GrA weathering steel plate can be realized.
