NIKROTHAL ALLOYS 40, 60, 70, and 80 are members of the Nikrothal family, which represent one of two main types of electric-resistance alloys. Nickel-chromium (80Ni-20Cr, for example), developed around the turn of the century, was used as heating-element material in industrial furnaces and electric household appliances. Nikrothal alloys offer advantages in heating-element applications requiring very good mechanical properties in the hot state. This datasheet provides information on composition, physical properties, and tensile properties as well as creep. It also includes information on corrosion resistance. Filing Code: Ni-529. Producer or source: Kanthal Corporation.

TECHALLOY A (80-20) is a nickel-chromium electrical resistance alloy for operating temperatures up to 2150 F. It is non-magnetic, highly corrosion resistance, and has a lower temperature coefficient of resistance than other alloys for heater elements. This datasheet provides information on composition, physical properties, elasticity, and tensile properties. It also includes information on corrosion resistance as well as forming, heat treating, machining, joining, and surface treatment. Filing Code: Ni-220. Producer or source: Techalloy Company Inc..

CHROMEL-D is a special 35-20 nickel-chromium alloy developed primarily for use as heating elements in industrial furnaces designed to operate in the critical temperature range between 1500 and 1800 F. with controlled atmospheres. This datasheet provides information on composition, physical properties, hardness, and tensile properties as well as creep. It also includes information on high temperature performance and corrosion resistance as well as joining. Filing Code: SS-98. Producer or source: Hoskins Manufacturing Company.

KANTHAL-D is a resistance alloy employed advantageously for heavily-stressed electric heating apparatus, and is particularly suitable for heating elements in industrial furnaces and ceramic kilns. This datasheet provides information on composition, physical properties, hardness, and tensile properties as well as fracture toughness. It also includes information on high temperature performance and corrosion resistance as well as joining. Filing Code: SS-34. Producer or source: Aktiebolaget Kanthal.
