How about price trends of ASTM A302 pressure vessel steel sheet this week

The salesman of the company is familiar with all aspects of knowledge. Understand the company profile: group, company profile, various honor certification, enterprise's functional strength and other advantages analysis. Know the main product brand types and specifications of the company, and know the special knowledge of the product (production process and advantages of the product, simple identification method of product quality, etc.)

A514Gr.Q material is a quenched and tempered high-strength weldable steel plate under the ASTM standard. It is mainly used in places where high tensile strength and high yield are required, engineering vehicle lifting gears, and racks for offshore platforms. Depending on the thickness, its hardness is between 235-290, the yield is greater than 630MPa, and the tensile strength is greater than 700MPa.

There is an inherent difference between the cold forming properties of low-alloy high-strength steel and carbon structural steel. First of all, a certain amount of permanent deformation of low-alloy high-strength steel requires greater force than ASTM A302 pressure vessel steel sheet, carbon structural steel of the same size. Second, when low-alloy high-strength steel is formed, a slightly larger allowable amount for springback should be given. According to experience, unless the low-alloy high-strength steel is processed to control the shape of inclusions, it is necessary to use a larger bending radius than carbon structural steel during cold forming.

Japan is a typical shipping first, and its raw materials are imported from Oceania, central and South America and other Asian countries. Most of the ASTM A302 pressure vessel steel sheet steel produced is exported to China and other Asian countries, and a small amount is exported to America. Shipping is the main way of its ASTM A302 pressure vessel steel sheet steel international transportation. According to the data, steel goods account for about 20% of the total sea freight in Japan. The domestic transportation of Japanese steel is mainly truck.
