The output of stainless steel affects the price: when the market output of A588 Gr A ASTM steel grade, stainless steel is lower than the market demand, the price will rise. This is related to the operating rate of global stainless steel mills and the price trend of stainless steel raw materials. As a stainless steel buyer, it is necessary to control the purchasing stock reasonably, find a suitable and stable supplier, and understand the company's demand for future production.

The weldability of A588 Gr A ASTM steel grade is good. It means that under certain process and construction conditions, A588 Gr A ASTM steel grade can obtain good performance after welding. Weldability is a measure of the hot workability of steel. Weldability can be divided into weldability in construction and weldability in use. Weldability in construction refers to the sensitivity of cracking in weld metal and near seam zone, and hardening sensitivity of steel in near seam zone. Good weldability means that under certain welding process conditions, the weld metal and steel near the seam do not produce cracks. Weldability in use means that the mechanical properties of weld and HAZ steel are not lower than those of base metal.

When phosphorus, copper, chromium, nickel and other trace elements are added to the steel, A588 Gr A ASTM steel grade, a dense and strong adhesive protective film will be formed on the steel surface, which will prevent the corrosion from spreading and developing inward, and protect the substrate under the rust layer, so as to slow down the corrosion rate. The amorphous spinel oxide layer of about 50 μ m ~ 100 μ m thickness formed between the rust layer and the substrate is compact and has good adhesion with the substrate metal.
