Abstract Allegheny Ludlum AL 15-7 Alloy is a chromium-nickel-molybdenum-aluminum semi-austenitic stainless steel. It is heat treatable to high strength and it has a moderate level of corrosion resistance. It is available both as a conventionally melted product and as vacuum arc or electroslag refined material. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on high temperature performance and corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: SS-496. Producer or source: Allegheny Ludlum Corporation.

Discover problems of welds is not so easy from time to time. Specially, If welding was made in rough environmental conditions such as high temperature, humidity and dusty wind. It is necessary to provide good conditions to realize basic step of welding. For welding, have been used welding procedures specification and procedure qualification record. However, difficult conditions, documentations rightness or human errors are always here. Common weld defects like cracks, porosity, lack of penetration and distortion can compromise the strength of the base metal, as well as the integrity of the weld. According of site inspection, there were suspicion of intercrystalline corrosion, inclusions, leaker or segregation in root of weld, root weld stretches to the pipe inside, the welded pipes are not in axially level, the not proper surface treatment after welding and keep the intervals between single welds to not overheat the pipes.
