Incoloy , H, and HT are nickel-iron-chromium alloys with good strength and excellent resistance to oxidation and carburization in high-temperature exposure. These nickel steel alloys are identical except for the higher level of carbon in alloy H, and the addition of up to 1. Incoloy was the first of these alloys and it was slightly modified into Incoloy H. This modification was to control carbon.

ASTM B407/B358 Incoloy 800HT Pipe
It covers them in the form of cold-worked or hot-finished annealed seamless pipes and tubes. They are annealed to produce controlled grain size required for optimum properties in this temperature range. These Incoloy alloys possess very high resistance to chloride-ion stress-corrosion cracking, and also exhibits good resistance to polythionic acid cracking. Hence, these pipes and tubes are highly applicable in high temperature petrochemical environments. Scope And Manufacturing As per ASTM B specifications ,the alloys should be heat treated at specified annealing temperatures and should adhere to the chemical composition limits for nickel, chromium, iron, manganese, carbon, copper, silicon, sulfur, aluminum, titanium, columbium, molybdenum, niobium, tantalum, phosphorus, tungsten, cobalt, nitrogen, and boron as specified in ASTM B specification.
