High quality nm500 steel plate elastic modulus

ASTM A516 is also known as ASME SA516. The A516 / SA516 standard specification for pressure vessel plates, carbon steel, for moderate- and lower-temperature service. A grade NM500 steel plate intended primarily for service in welded pressure vessels where improved notch toughness is required, and is normally found in moderate and lower temperature applications. All plates over 1-1/2″ Thick are required to be normalized. A516 Grade 70 steel is the most popular pressure vessel grade of steel plate in the industry.

Our company's NM500 steel plate power boilers, heating furnaces of double bars, double high lines and medium and thick plates all adopt heat storage technology, which can fully use blast furnace gas; the ladle baking, Maerz active lime kiln and medium and thick plate heat treatment furnace all burn converter gas, which can improve the NM500 steel plate utilization rate of secondary energy and realize negative energy steelmaking in steelmaking process.

Hot-rolled steel sheet / cold-rolled steel sheet: Steel ingots or slabs are difficult to deform at normal temperature and difficult to process. They need to be heated to 1100 ° C to 1250 ° C for rolling. This NM500 steel plate rolling process is called hot rolling. Rolling at room temperature is generally understood as cold rolling. However, from the point of view of metallurgy, the boundary between hot rolling and cold rolling should be distinguished by the temperature of metal recrystallization, that is, rolling below the recrystallization temperature is cold rolling; Rolling above the recrystallization temperature is hot rolling.

Vanadium is a weak deoxidizer. Adding vanadium into NM500 steel plate steel can reduce the adverse effects of carbon and nitrogen, effectively improve the strength, but sometimes also increase the tendency of welding hardening, vanadium is also a commonly used trace alloy element.

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.
