Product Description

Q345R+316L Hot-rolled composite stainless steel clad plate for High-sulfur crude oil refining tower equipment
Stainless Steel-Carbon Steel Clad Plates are energy-saving, eco-friendly composite materials manufactured using advanced hot-rolling composite technology. This process achieves 100% metallurgical bonding between the carbon steel substrate (base layer) and stainless steel cladding (corrosion-resistant layer). The product combines the high strength/toughness of carbon steel with the corrosion/wear resistance and anti-magnetism of stainless steel, complying with GB/T8165-2008 and NB/T47002-2019 standards.

Key Advantages
Superior Performance
Substrate Materials: Q235B, Q345R, Q245R carbon steels, low-alloy steels, bridge/shipbuilding steels, and specialty plates.
Cladding Materials: 304, 316L, 1Cr13, duplex stainless steels (thickness: 0.5-15 mm).
Bonding Strength: Average shear strength ≥300 MPa (exceeding national standard 210 MPa).

Advanced Technology
Hot-Rolling Bonding (MESCO Patent):
Max. dimensions: 4,500 mm × 15,000 mm
100% interface bonding rate | Pollution-free | Continuous industrial production
vs. Explosive Cladding: No noise/pollution, no climate restrictions, but thickness limited to ≤70 mm.

Cost Efficiency
40-60% cost reduction vs. solid stainless steel, lowering equipment expenses significantly.
