Overview
ASTM B514 is a standard specification for Nickel-lron-ChromiumAlloy Welded Pipes.The ASTM B514 specification covers Incoloy800 and lncoloy H alloys. It covers them in the form of cold-worked and annealed welded pipes which are applicable forgeneral corrosive service and heat resisting applications.ASTMB514 Incoloy 8o0 Welded Pipes are usually applicable in servicetemperature up to 1100 F or 593 C. Whereas, ASTM B514Incoloy 800H Welded Pipes are usually applicable in servicetemperature above 1100 F or 593 C where resistance to creepand rupture is required.They are annealed to produce controlledgrain size required for optimum properties in this temperaturerange. These Incoloy alloys possess very high resistance tochloride-ion stress-corrosion cracking, and also exhibits goodresistance to polythionic acid cracking. Hence,these pipes and tubes are highly applicable in high temperature petrochemicalenvironments.
