Customized EN steel grade S450J0 material structural steel plate

ASTM A217 stainless steel castings in the product form of valves, flanges, fittings and other pressure-containing parts. ASTM A217/A217M covers one grade of martensitic stainless steel and nine grades of ferritic alloy steel which are primarily utilized in high-temperature and corrosive service. It includes C-Mo alloy steel: Grade WC1; Cr-Mo alloy steel: Grade WC4, WC5, EN steel grade S450J0 material, Grade WC6, WC9, WC11, C5, C12; Cr-Mo-V alloy steel: Grade C12A; and Chromium Steel: Grade CA15.

It is our biggest wish that the steel material, specification and quantity can fully meet the requirements of users. With good reputation, high quality products and low price, we are willing to work together with old and new customers to create a great EN steel grade S450J0 material cause. Customers are welcome to visit our company at any time. We are always ready to support you.

Titanium microalloying is an element of EN steel grade S450J0 material strengthening complex with carbon and nitrogen. The addition of micro amount of titanium in the steel can fix almost all nitrogen and part carbon in the steel, so as to eliminate the strain aging phenomenon and improve the aging impact performance of the steel. At the same time, it can refine the grains and change the morphology of the compounds. According to the atomic weight ratio of Ti and N in EN steel grade S450J0 material tin formula (Ti = 3.4n), the content of Ti in steel should be controlled between 0.015 and 0.025%. Generally, the amount of ferrotitanium added to each ton of steel is 1kg.

Oxygen is a harmful element in EN steel grade S450J0 material steel. With the increase of oxygen content, the strength of EN steel grade S450J0 material steel increased, but the plasticity, especially the toughness, decreased significantly, and the weldability became worse. The presence of oxygen causes hot brittleness of EN steel grade S450J0 material steel.

The after-sales service department will pay return visit to each customer by call or email, report problems found during the return visit in time, and discuss with the production and quality inspection center to propose effective solutions and follow up in a timely manner, so as to ensure the benefits each customer are fully guaranteed, and to provide customers with more value-added services.
