Tool Steel S-7 Drill Rod, Air-Hardening

Tool Steel S-7 Drill Rod, Air-Hardening

S7 Drill Rod Tool Steel has very high toughness to withstand chipping and breaking and meets ASTM A681 specifications. S7 is used where superior strength is needed to keep sharp edges, such as on drills and punches.

Hardening S-7 Drill Rod: In a control temperature oven, heat slowly to 1750°F. For smaller pieces below 2.5" cross-section width, remove from heat and allow to air-cool. For sizes over that, up to 6" in cross-width, quench in oil to 1000°F, then remove and finishing aircooling to 150°F. For sizes larger than 6", quench in oil to 150°F.

Tempering S-7 Drill Rod: Temper your S-7 drill rod by reheating to 400-500°F for cold-working application, 900-1000°F for high-heat applications, to relieve the stresses caused by hardening process, and to achieve the hardness needed. The lower the temperature the s7 drill rod is reheated to, the higher the level of hardness remains. Reheat for no less than 1 hour, and up to two hours.
