304 Stainless Steel Clad Plate – Pressure Vessel Chemical Grade
Product Overview
Stainless steel clad bimetal plate is a cost-effective composite material that combines the structural strength of a carbon steel base layer with the corrosion resistance of a stainless steel cladding layer. Manufactured by explosion welding or hot roll bonding to achieve full metallurgical bonding, this Q235B + 304 grade delivers reliable pressure-bearing performance and general chemical corrosion resistance at approximately 30–50% lower cost than solid stainless steel plate. It is the standard material for chemical processing tanks, pressure vessels and process equipment.
Why Choose CNB Bimetal Clad Plate?
We source bimetal clad plates from specialized clad steel mills with strict bonding quality control. Every plate undergoes 100% ultrasonic bond inspection to guarantee complete bonding without delamination defects. We offer a full range of base and cladding material combinations, thickness ratios and sizes to match specific pressure, corrosion and temperature requirements. With custom cutting and edge preparation services, we deliver ready-to-fabricate clad plates for pressure vessel and tank construction.
