Q235+2205

Thickness

Standard total composite thickness: 3mm-100mm, customizable; 2205 duplex stainless steel cladding thickness: 0.8mm-10mm, Q235 carbon steel base thickness matched on demand, ultra-thin/ultra-thick non-standard customization available, U-shaped and special-shaped bending parts can be processed

Length

Standard plate length: 2000mm/2440mm/3000mm/6000mm, maximum 12000mm extra-long size customizable; special-shaped parts customized according to drawing dimensions, cut-to-length leveling and arc bending processing supported

Width

Standard plate width: 1500mm/1800mm, maximum customizable width 2200mm, slitting and special-shaped cutting supported

Weight

Calculated by actual thickness and size. Theoretical weight formula: Total weight = (Q235 carbon steel base weight + 2205 duplex stainless steel cladding weight). Q235 density: 7.85g/cm³, 2205 duplex steel density: 7.8g/cm³, accurate weight calculation and quotation provided

Surface Finish

2205 cladding: 2B finish, BA mirror finish, brushed finish, pickling passivation; Q235 base: pickling passivation, anti-rust oil, sandblasting pretreatment; special processes such as fluorocarbon spraying and titanium plating customizable on demand

Application

Mainly for strong corrosion and high stress working conditions, widely used in chemical acid-base storage tanks, seawater desalination equipment, marine engineering, oil and gas exploitation, desulfurization and denitrification equipment, paper/salt making equipment, pressure vessels, etc. It combines the structural strength of Q235 with the dual-phase corrosion resistance and fatigue resistance of 2205
