Abstract

Carpenter Low Expansion 43-PH is an age hardenable iron/nickel austenitic alloy. It differs from most metals and alloys in that it has a constant modulus of elasticity over a temperature range of -30 to +150 F(-47 to +66 C). Its thermal elastic coefficient can be adjusted to zero or near zero by varying the aging temperature and degree of cold work prior to aging. The alloy possesses high strength and good formability. 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, and joining. Filing Code: Fe-91. Producer or source: Carpenter.
