What harm does the excessive weld height of S420ML steel bring

With the development of China's S420ML steel market economy, the company vigorously implements the strategy of industrialization, internationalization and diversification, promotes group operation, intensive development and lean management, and builds the company into a company with scientific development concept, continuous innovation vitality, excellent corporate culture and strong sense of social responsibility through rich series of S420ML steel products and project portfolio and complete operation network And international first-class competitiveness of modern enterprises.

14Cr1MoR steel plate is suitable for petrochemical, nuclear power, steam turbine cylinder block, thermal power and other high-temperature and high-pressure large-scale equipment that is connected to hydrogen or hydrogen mixed media.Chemical element composition of S420ML steel container plate:C: 0.05%-0.17%Si: 0.50%-0.80%Mn: 0.40%-0.65%P: 0.010%-0.012%Cr: 1%-1.5%Mo: 0.45%-0.65%Ni: 0.20%-0.25%

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 S420ML steel has good processing performance. Rimmed steel does not have large concentrated shrinkage cavities, uses less deoxidizer, and the cost of steel is low.

When the stainless steel plate is alloyed with chromium, the type of surface oxide is changed to that formed on pure chromium metal. This tightly adherent chromium rich oxide protects the surface from further oxidation. This kind of oxide layer is very thin, through which we can see the natural luster of the steel surface, so that S420ML steel, stainless steel has a unique surface.
