Comparative Tensile Strength and Shear Strength of Detaclad Explosion Clad Products • Introduction • Experimental Procedure • Test Results and Discussion • Conclusions
Comparative Tensile Strength and Shear Strength of Detaclad Explosion Clad Products • Cladding metal thickness typically too thin for tensile test coupon • Clad specifications do not require clad tensile testing or identify minimum strength requirements • Shear testing is common, but clad tensile strength data limited
Crude Distillation Column • Internal components attached to column walls • Tensile strength data supports analysis of direct attachment to the clad surface
Comparative Tensile Strength and Shear Strength of Detaclad Explosion Clad Products • Testing program initiated by DMC to investigate clad tensile strength • Test broad range of clad combinations • Compare results with cladding metal and base metal mechanical properties and shear strength data
Comparative Tensile Strength and Shear Strength of Detaclad Explosion Clad Products • Test material selected from production plates produced at DMC between Jan-Jul 07 • Cladding metal thickness>=9.5mm • Heat treatment = production plate HT • Tests machined and tested from same test block • Shear • Subsize Clad Tensile (6.4mm gauge diameter) • Base Metal Tensile

Stainless Steel and Nickel Alloy Shear Strength vs. Tensile Strength
Comparative Tensile Strength and Shear Strength of Detaclad Explosion Clad Products Conclusions: • Clad tensile strength > clad shear strength • Tensile strength of SS, nickel alloy explosion weld > carbon steel tensile strength • Clad tensile strength of Cu alloy and titanium clad well above minimum tensile strength of cladding metals • Good correlation between base metal through thickness and transverse tensile strength • All of the base metal tensile tests after cladding were compliant
