316L Stainless Steel Clad Plate – High Corrosion Marine & Petrochemical Grade
Product Overview
316L stainless steel clad bimetal plate is a premium corrosion-resistant composite material designed for harsh chloride and marine environments. Built on Q345R pressure vessel carbon steel base with molybdenum-alloyed 316L stainless cladding, it delivers superior pitting and crevice corrosion resistance compared with standard 304 grade. This high-performance clad plate provides the strength of carbon steel with premium corrosion resistance at a fraction of the cost of solid 316L steel, making it ideal for petrochemical, marine and coastal infrastructure.
Why Choose CNB 316L Clad Plate?
Our 316L clad plates are manufactured with strict control over cladding composition and bonding integrity to ensure consistent corrosion performance. Every plate undergoes full ultrasonic inspection and corrosion verification to guarantee reliable service in harsh environments. We offer various base strength grades and cladding thicknesses to match specific pressure and corrosion requirements, with value-added machining services for tube sheets and custom components.
