ASTM B619 UNS R30556 Class I Welded Pipes
Description: Produced from flat-rolled alloy by an automatic welding process without the addition of filler metal, and then furnished either as-welded and solution annealed, or welded, sized, and solution annealed. This class provides excellent structural integrity and uniform properties for demanding high-temperature and high-stress environments.
Features: Offers inherent strength and toughness, consistent wall thickness, and enhanced resistance to internal pressure and thermal stresses at elevated temperatures. The precise control over the welding and annealing processes ensures high-quality and reliable performance in critical high-temperature applications.
Applications: Used in various sections of industrial furnaces, gas turbine hot sections, and high-temperature structural components where exceptional high-temperature strength, and resistance to oxidation, sulfidation, and carburization are paramount.
ASTM B619 UNS R30556 Class II Welded Pipes
Description: Manufactured by forming an alloy steel strip into a cylindrical shape and then welding the edges longitudinally. Subsequent to welding and prior to final heat treatment, Class II pipes are cold worked either in both the weld and base metal or in the weld metal only, followed by solution annealing. This cold working step further refines the microstructure and enhances mechanical properties.
Features: Provides improved mechanical properties and a more refined grain structure due to the cold working process. This class offers enhanced performance for applications requiring superior strength and integrity, balancing performance with cost-effectiveness for a wide range of diameters and wall thicknesses.
