JESSOP No. 200 is a non-magnetic, austenitic steel developed especially for the electrical industry. It has low magnetic permeability and high electrical resistance. Jessop No. 200 is ideal for a great number of applications requiring low permeability material where corrosion resistance is not a factor and where cost is important. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as fracture toughness. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: SA-99. Producer or source: Jessop Steel Company.
