What is JIS SM490YA plates equivalent steel in China

The company adheres to the people-oriented concept and takes "learning, sharing, gratitude, integrity, respect and responsibility" as the enterprise values. Advanced equipment, scientific standardized management, strict quality assurance system and high-quality team are the core competitiveness of the company. The company will continue to provide customers with JIS SM490YA plates high-quality, timely and perfect steel products and services under the guidance of the mission of "striving for perfection to meet customer needs".

A573Gr70 plate technical conditions: the chemical composition and mechanical properties of A573Gr70 steel are produced in line with ASTM A573. When ordering, additional impact, flaw detection, z direction, composition control, performance requirements beyond the standard can be added. Available heat treatment processes of JIS SM490YA plates, A573Gr70 plate: hot rolling, controlled rolling, normalizing, tempering, quenching, normalizing + tempering. Our company supply flaw detection Z15-Z35 thickness direction performance.

Low-alloy steel plates have low carbon content, and because ferrosilicon is not used for deoxidation, the silicon content in steel is often <0.07%. The outer layer of rimmed steel is crystallized in a rimmed state, so the surface layer is pure and dense, the surface quality is good, and the Zhengzhou low alloy steel plate JIS SM490YA plates has good processing performance. Rimmed steel does not have large concentrated shrinkage cavities, uses less deoxidizer, and the cost of steel is low.

With our own engineers, metallurgists and CAD draftsmen, we can provide total support from design through to machined casting. OEM precision casting investment JIS SM490YA plates casting auto parts, customized investment casting auto parts, custom precision casting automobile parts, truck casting iron fitting parts.Precision Casting: Tooling making → Wax pattern → Shall making → Chemical analysis → Pouring → Measurement & inspection → Heat Treatment → Processing → Finished product.
