ISO185/JL/250 (Gray Cast Iron)

摘要

ISO 185/JL/250 is an intermediate-tensile-strength gray cast iron that has a pearlitic matrix and a tensile strength of 250-350 MPa (36-51 ksi), when determined on test pieces machined from separately cast, 30 mm (1.2 in.) diameter test bars. Compared with the lower strength gray cast iron grades, ISO 185/JL/250 contains lower carbon and silicon contents and has superior wear resistance, while still maintaining good thermal conductivity, damping capacity, and machinability.
