Explosive Clad Plate ASME SA516 Gr.70 Carbon Steel Cladding ASME SB127 Monel 400

ASME SA516 Gr.70 Explosive Cladding Plate with ASME SB127 monel 400, Explosion Bonded Clad Plate

ASME SA516 Gr.70 CARBON STEEL CLDDING SB127 MONEL 400 PLATE means a plate where the structural base material is carbon steel conforming to SA-516 Grade 70, and it is clad (bonded) on one or both sides with Monel 400 alloy conforming to SB-127.

Purpose of Cladding:

• This construction combines the cost-effectiveness and structural strength of carbon steel with the superior corrosion resistance of Monel 400.

• The carbon steel provides the primary strength and thickness required for pressure containment or structural support.

• The Monel 400 layer protects the carbon steel from aggressive corrosive environments it would otherwise rapidly degrade in.

Common Cladding Material Combinations (Structural Base + Corrosion-Resistant Cladding)

Key Characteristics of Cladding Materials:

• Base Thickness: Predominantly carbon steel (SA-516 Gr. 70).

• Clad Thickness: A relatively thin layer of Monel 400 (SB-127), typically specified as a minimum nominal thickness or as a percentage of the total thickness.

• Bond: The two metals are metallurgically bonded (usually by roll bonding or explosion bonding) to ensure integrity and good heat transfer.

• Performance: The plate behaves structurally like carbon steel but exposes the highly corrosion-resistant Monel 400 to the process fluid or environment.

When to Use Cladding vs. Solid Alloy?

1>. Cladding: High-pressure vessels, heat exchangers, large structures needing corrosion resistance.
2>. Solid Alloy: Small components, extreme temperatures/purity (e.g., semiconductor furnaces).

For specific project needs (e.g., temperature, acid concentration), consult corrosion charts to select the optimal cladding alloy!

Applications

• Pressure vessels and heat exchangers handling corrosive chemicals (e.g., HF acid, chlorides, caustic).

• Flue gas desulfurization (FGD) scrubbers and ductwork.

• Marine and offshore components exposed to seawater.

• Chemical processing equipment (reactors, tanks, columns).

• Pulp and paper digesters and bleach washers.

• Desalination plant components.
