Product Overview: 304 Explosion Welded Stainless Steel Composite Plate 6+2mm
Our 304 stainless steel composite plate is manufactured by advanced explosion welding technology, adopting 6mm base layer matched with 2mm 304 stainless steel cladding layer, which is a high-performance composite metal material compliant with international industrial standards. The product takes carbon steel as the base material and 304 austenitic stainless steel as the surface cladding material, realizing perfect combination of high mechanical strength of carbon steel and excellent corrosion resistance of stainless steel. The explosion welding process forms a metallurgical bonding interface between two metals, with no gaps or delamination, effectively solving the bonding failure problem of traditional composite plates. All products are produced in accordance with GB/T 8165, ASTM A240 and other international mainstream standards, with standardized material proportion and precise size control, suitable for various industrial anti-corrosion and structural bearing scenarios.
Core Advantages with Data Support
1. Reliable Explosion Welding Bonding: The explosion welding interface bonding strength reaches ≥210MPa, far higher than the national standard requirement, ensuring no interface separation, cracking or peeling during cutting, bending, rolling and other secondary processing. The bonding rate of the whole plate is 100%, meeting high-standard industrial processing requirements.
2. Precise Fixed Size Specification: Standard 6+2mm thickness configuration, overall thickness tolerance controlled within ±0.1mm, flatness error ≤0.5mm/m. Customizable width and length range, which can meet the dimensional matching requirements of standardized industrial equipment processing.
3. Excellent 304 Material Performance: The 304 stainless steel cladding layer has chromium-nickel alloy components, with good acid and alkali corrosion resistance, oxidation resistance temperature up to 870℃, stable performance in high-temperature and humid working environments, and long service life.
4. Cost-Effective Structural Design: Replace full stainless steel plate with composite structure, reduce material cost by 30%-40% on the premise of ensuring corrosion resistance and structural strength, and improve the economic benefit of engineering projects.
Application Scenarios & Industry Solutions
This 6+2mm 304 explosion welded composite plate is widely used in petrochemical, chemical equipment, food processing, environmental protection and other industries. It is specially applicable for manufacturing pressure vessel shells, chemical storage tank liners, food grade reaction equipment, waste gas and waste water treatment equipment, and industrial heat exchanger plates. For petrochemical corrosion-resistant equipment, it can resist medium corrosion such as petroleum and chemical solvents; for food processing equipment, it meets food-grade anti-rust and sanitary standards; for environmental protection equipment, it adapts to long-term humid and corrosive working conditions, providing stable structural protection for industrial equipment.

Quality Control & Certification
We implement full-process quality inspection for all composite plates. Raw materials are inspected for chemical composition and mechanical properties before production to ensure compliance with ASTM and GB standards. Semi-finished products undergo ultrasonic nondestructive testing to detect internal gaps and delamination. Finished products are tested for bonding strength, dimensional accuracy and surface flatness. The factory has complete production inspection equipment and passes ISO9001 quality management system certification, all products support third-party testing and inspection, and provide official inspection reports.
Packaging & Delivery
Products are packaged with waterproof plastic film + wooden pallet reinforcement, with anti-collision and moisture-proof protection, avoiding deformation and surface damage during transportation. Standard specifications are in stock, delivery time is 3-7 working days; customized specifications take 7-15 working days. We support sea freight, air freight and express delivery, and provide professional packaging and logistics tracking services to ensure intact product delivery.
