The chemical composition of nm400 steel equivalent

As an experienced world class steel materials supplier and exporter, logistics and fast delivery is a crucial step to us. Our logistics department and shipping department take the responsiblity to allocate and transport steel materials from our mill and warehouse to customer port or designated destination. The cooperation of the two departemts are excellent and that powerfully support our fast delivery, and strive for shorter time for customers to receive steel materials.

ASTM A387 Grade 5 and ASTM A387 Grade 9 Steel plates NM400 steel equivalent have good corrosion and heat resistance for alloy element chromium and molybdenum, which is needed in sour oil gas industry.

S960Q plate implements standard EN10025-6S960Q plate application: European standard high-strength steel plate, corresponding to the national standard Q960. NM400 steel equivalent, S960Q plate is suitable for manufacturing various construction machinery, such as drilling rigs, electric shovel, electric wheel dump trucks, mining vehicles, excavators, loaders for mining and various engineering construction, bulldozers, various cranes, coal mine hydraulic supports and other mechanical equipment and other structural parts.S960Q plate delivery status: normalizing, normalizing + tempering, quenching and tempering, etc.;Technical requirements for NM400 steel equivalent, S960Q plate, NM400 steel equivalent: UT, Z15-Z25-Z35 thickness direction performance requirements, high-strength and high-toughness.

Special boiler steel is derived from carbon structural steel. The chemical composition of boiler steel is basically the same as that of high-quality carbon structural steel of the same level, but the NM400 steel equivalent steel mechanical property requirements are more strict, especially for impact toughness. And the aging sensitivity is required to be small. The boiler steel should be deoxidized and the non-metallic inclusions should be removed during smelting. The structure should be uniform. The grain size should be controlled in 3-7 grades. The defects such as interlayer, shrinkage, porosity and porosity should be minimized.

We have a professional after-sales service team, the company has developed a clear service process and service standards, after-sales service team members strictly perform after-sales procedures, comply with service standards. The most important thing is that we have set up the correct concept of after-sales service, "customer first, sincere service for users".
