Q235R and Q345R are 2 common steel materials for pressure vessel equipments, for a long time many pressure vessel manufacturers have some misunderstandings on how to choose between these 2 steel materials. For exampleObviously Q345R has the advantage on pressure vessel yield strength; while Q245R shows advantage on Calculation of container stiffness, and for Q245R is carbon steel, it has price advantage compared to low alloy steel-Q345R.
Through alloying of Cu, Mn, Si, Al, and simply adjusting some element contents of ordinary low carbon steel (Q235 steel), economic 09CuPCrNiA steel plate with good atmospheric corrosion resistance and comprehensive mechanical properties can be produced without changing the production process of Q235 steel. Atmospheric corrosion resistant 09CuPCrNiA steel plate is mainly used for railway, vehicle, bridge, tower and other steel
s355jr steel coil good corrosion resistance dimension
Type 410 is a general hardenable, martensitic stainless steel. It combines the superior wear resistance of high carbon alloys with the excellent corrosion resistance of chromium stainless. Its strength, good ductility and resistance to corrosion in mild atmospheres, steam and mild chemical environments make it well suited for highly stressed parts.
Steel Coil Coating for Corrosion Resistance September 1, 2016. ASTM B117 salt spray test results, performed on HDG G235 with hexavalent chemtreat vs. HDG G40 with InterCoat ChemGuard 315, as exposed for 1,500 hours. The RoHS compliant coating applied by Chemcoaters is made with trivalent chrome vs. hexavalent chrome, a known carcinogenic.
