COVER STORY
Kobelco become Maruichi; commitment to quality remains unchanged
On June 1, Kobelco Steel Tube Co., Ltd. changed its name to Maruichi Stainless Tube Co., Ltd. The company continues to provide a stable supply of high-quality seamless stainless pipes and tubes. It also produces high-growth products such as semiconductor bright annealed pipes and precision bright annealed tubes for direct injection automotive engines.

WELDING DUPLEX
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.

CLAD PLATE
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.

END USER INTERVIEW   
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    
Weld overlay brings new life to distillation column
When one of Italy’s leading refineries found extensive corrosion in one of its crude distillation units it relied on Sulzer Chemtech’s tower maintenance expertise to repair its equipment and restore operations.

WELDING
