Abstract RA-330 is an austenitic, non-magnetic, corrosion and heat resisting, high nickel-chromium alloy steel. It does not respond to any heat treatment for hardening. It has a greater resistance to heat and thermal shock than the other grades of austenitic steel. This datasheet provides information on composition, physical properties, elasticity, and tensile properties as well as creep. It also includes information on high temperature performance and corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: SS-11.
