INTRODUCTION

Stainless steel clad plate is a composite steel plateformed by metallurgical bonding of a carbon steel base layerand a stainless steel cladding layer. It combines themechanical strength of carbon steel with the corrosionresistance of stainless steel, and is widely adopted in themanufacturing of petroleum, chemical, coking and power equipment.

The base layer generally adopts carbon steel grades such as Q235B and Q355B.The cladding layer can be selected from stainless steel materials including 304, 316L,310S, 2205 and 1Cr13, with freely combinable thicknesses for both layers

This material is manufactured by explosive cladding or hot rolling processes:
Explosive cladding is suitable for thick plates and bonding of special metals, yet it
brings environmental pollution risks; the hot rolling process features high production efficiency and can produce thin plates and coils.

The product supports hot pressing, cold bending, cutting, welding and othermachining processes. Its interfacial shear strength exceeds 400 MPa. The cold rollingprocess can produce high-precision coils with a thickness of 0.6 mm and aboveReplacing solid stainless steel plates with clad plates cuts costs by over 30%. It greatlyextends the service life of equipment such as bolted tanks, desulfurization towers,denitrification towers and coal bunkers, and is also applied in wastewater treatment,construction formwork and other scenarios.

PRODUCTION PROCESS FLOW

PRODUCT ADVANTAGES

1. Lower Procurement CostsReplacing solid stainless steel plates with stainless steel clad plates reducesequipment manufacturing costs without compromising equipment performance. Foridentical equipment fabrication, material costs can be cut by more than 30% whenstainless steel clad plates are used
2. Extended Service LifeIt retains the corrosion resistance, wear resistance, non-magnetic property andattractive appearance of solid stainless steel, while inheriting carbon steel’ s excellentweldability, formability, ductility and thermal conductivity. It enhances equipmentanti-corrosion performance and effectively prolongs service life
3. .Higher Manufacturing EfficiencyAdopting advanced hot rolling technology, the base and cladding layers are bonded at high temperature and pressure to form atomic-level metallurgical bonding, delivering smooth, seamless surfaces. Compared with conventional processes, this technology is more eco-friendly with shorter lead times, thus boosting overall equipment production efficiency.
4. Higher Plate Utilization RateUnlike solid stainless steel, which is only available in standard widths (1500 mm, 1800mm, 2000 mm, etc.), stainless steel clad plates can be fully customized to customer requirements. The total plate thickness, cladding thickness and product width can be freely designed with complete specifications, improving material utilization and reducing steel plate waste.
