Sigma phase: a metallurgical challenge when welding duplex
While high strength was the focus of alloy development for many years, today a range of other properties are also essential. These include toughness, stiffness, hardness, ductility, and corrosion resistance.

Tri-ply metal clad plate for ultimate griddle performance
Clad plate materials offer a wide range of advantages in which the end product combines the best properties of each metal: strength, corrosion resistance, lightweight, cost, and thermal conductivity. As a result, clad products produce a material superior to any of the individual metals taken alone.

Welders beware: diversity in stainless steel
Many welding inspectors begin their careers working on manufacturing lines or in construction. Randall Stremmel began with aircraft carriers and submarines. From this auspicious start, he moved into the energy sector, completing oil and gas projects in Ohio and eventually Houston, Texas. He recently merged his consulting company with another to form Oso Partners. 

Weld overlay brings new life to distillation column
