The fundamental difference is simple: No melting means no fusion dilution. In fusion welding: CRA filler material + melted steel substrate → liquid weld pool → solidified mixed composition.In explosion bonding: CRA plate + steel plate → high-speed impact → solid-state metallurgical bonding.The CRA layer does not become diluted by the carbon steel substrate. The alloy composition remains the same as the original CRA plate.

Dilution Ratio is often considered only a welding parameter. However, in CRA clad pipe applications, it is directly connected with corrosion reliability.During fusion-based cladding, interaction between CRA filler metal and carbon steel substrate can influence:Chemical composition,Microstructure,Passive film stability;Corrosion resistance.

PREN and CPT provide valuable guidance for evaluating corrosion-resistant alloys.For large industrial equipment, explosion-bonded clad plates provide a practical approach: High-performance CRA surface protection + economical structural steel strength.This combination allows engineers to achieve long service life in aggressive environments while maintaining project competitiveness.

Titanium and titanium alloys represent the highest level of corrosion resistance in chloride-dominated environments. While stainless steels and nickel alloys serve well across many industrial sectors, titanium becomes the definitive solution when:Seawater exposure is continuous,Chlorine systems are involved,Lifecycle reliability is critical,Corrosion failure is not acceptable
