Stock S355J2W low alloy steel specification

SA516Gr60 material, SA516Gr70, SA516Gr60N, SA516Gr70N steel plate in thickness ≤1.5in (40mm) is usually supplied in rolled state. The plate can also be ordered according to normalizing or stress relief, or normalizing plus stress relief. SA516Gr60 steel plate when thickness> 1.5in. (40mm) should be normalized. Unless otherwise specified by the customer, , SA516Gr60 steel plate (thickness ≤40mm) should be normalized when there is a notch toughness requirement.The company adheres to the people-oriented concept and takes "learning, sharing, gratitude, integrity, respect and responsibility" as the enterprise values.

The company will continue to provide customers with high-quality, timely and perfect steel products and services under the guidance of the mission of "striving for perfection to meet customer needs".
S355J2W low alloy steelFirst to determine the welding methods, such as hand arc welding, submerged arc welding and tungsten argon arc welding, melting polar gas shielded welding machine, and so on are very many different kinds of welding method, can only be chosen according to specific situation, determine the welding method, and make welding process parameters, different kinds of welding process parameters, such as manual welding mainly includes: electrode model (or brand) diameter, current, voltage, welding power source type and polarity connection, welding layer number, number, inspection method, etc.
S355J2W low alloy steel,When phosphorus, copper, chromium, nickel and other trace elements are added to the steel, 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.
S355J2W low alloy steelS355J2W low alloy steel,After-sales service team is a key department to test the steel quality Product quality is always the foundation of our survival and development The company's full inspection from raw materials to finished products; and implements standardized, scientific, and strict internal quality control and management systems in accordance with the process flow during the production process; products can only leave the factory if qualified, and follow-up problem solving systems are implemented in after-sales services to guarantee the customers’ interest,S355J2W low alloy steel.
