Search Results for ACI Type HT

ACI Type HT is an iron-chromium-nickel alloy containing about equal amounts of iron and alloying elements. The high nickel content makes this grade useful in resisting the thermal shock of rapid heating and cooling. In addition the alloy is resistant at high temperature to oxidation and carburization, and has good strength at heat-treating temperatures. This grade is widely used for general heat-resistant applications in highly stressed parts. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as fracture toughness and creep. It also includes information on high temperature performance and corrosion resistance as well as casting, heat treating, machining, and joining. Filing Code: SS-361. Producer or source: Various stainless steel casting companies.

Type HN is an iron-chromium-nickel alloy containing sufficient chromium for good high-temperature corrosion resistance and with nickel content in excess of the chromium. This alloy has properties somewhat similar to the more widely used ACI Type HT alloy but with better ductility. Type HN is used for highly stressed components in the 1800-2000 F temperature range. It is used in the aircraft, automotive, petroleum, petrochemical and power industries for a wide range of components and parts. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as creep. It also includes information on high temperature performance and corrosion resistance as well as casting, heat treating, machining, and joining. Filing Code: SS-410. Producer or source: Various stainless steel casting companies.

Type HW is a nickel-base austenitic casting grade with good resistance to oxidation and carburization and is especially suited for applications where wide and/or frequent fluctuations in temperature occur. This datasheet provides information on composition, physical properties, and elasticity as well as creep. It also includes information on high temperature performance and corrosion resistance as well as machining and joining. Filing Code: Ni-449. Producer or source: Steel Founders Society. Originally published as Alloy Digest Ni-37, November 1957, updated April 1994.

Type HH is an iron-chromium-nickel casting alloy having high heat, oxidation and corrosion resistance. It is recommended for furnace parts, salt pots, grate bars, belt conveyors and other parts operating up to 21008 F in intermittent service. It may be supplied in partially ferritic Type I or in wholly austenitic Type II depending on the applications and service requirements. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as fracture toughness and creep. It also includes information on high temperature performance and corrosion resistance as well as casting, heat treating, machining, and joining. Filing Code: SS-221. Producer or source: Stainless steel mills.

CHROMAX is a nickel-chromium-iron alloy suitable for operations at temperatures up to 1900 F. It resists corrosion, heat, and oxidation to a remarkable degree. It is supplied in the cast or wrought form. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as fracture toughness and creep. It also includes information on corrosion resistance as well as casting, forming, heat treating, machining, and joining. Filing Code: SS-6. Producer or source: Driver-Harris Company.

UNS NO. G50461 is a low-chromium alloy steel with boron added to increase its hardenability. This steel has medium hardenability and strength with good ductility. It is used in a wide range of machinery and tool applications where its properties meet the requirements. Another grade (UNS No. H50461) has similar properties but slightly wider ranges in percentages of carbon, manganese and chromium; this is known as the H-grade (Hardenability grade). This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on corrosion resistance as well as forming, heat treating, machining, joining, and surface treatment. Filing Code: SA-408.
