CIRCLE L17 is an age-hardening type of stainless steel having the desirable mechanical properties of the hardenable chromium type corrosion resisting steel combined with workability and corrosion resistance approaching 18-8 type stainless steel. It is hardenable by heat treatment to Rockwell C40-45. Cracking, distortion, decarburization, scaling and similar problems encountered after machining are virtually eliminated due to the low heat treatment temperature required for hardening. This datasheet provides information on composition, physical properties, hardness, and tensile properties as well as creep and fatigue. It also includes information on high temperature performance and corrosion resistance as well as casting, heat treating, machining, joining, and surface treatment. Filing Code: SS-71.
