Material Notes:
Carpenter S7 is a general purpose air hardening tool steel having high impact and shock resistance. It has good resistance to softening at moderately high temperatures. This combination of properties makes it suitable for many hot-work and cold-work applications. It is available as a DeCarb-Free product. DCF bars have been cold finished in the mill, eliminating the need for bar bark removal. Both Carpenter S7 and Bearcat, a trademark of Bethlehem Steel Corp., have the same AISI tool steel designation . . . S7.Information provided by Carpenter Technology Corporation.
