This auction is a for a single piece of Crucible Rex CPM T-15 High Speed HSS Tool Bit Blank. It is a 90 degree blank. Thin Flats dimensions .156 X .625 X 6. I can fit up to 10 of these in a package for $4.95 shipping and handling via Priority Mail. Anything over 10, I can fit in a Medium Flat Rate Priority Mail Box for $10.35. Ebay will not calculate the cost correctly so you will have to wait for me to send you an invoice before you pay. Here is the information from the Manufacturer: CPM® REX® T15(HS)* (AISI T15) CPM REX T15 is a super high speed steel made by the Crucible Particle Metallurgy (CPM) process. It is a tungsten type high speed steel containing high vanadium for excellent abrasion resistance, and cobalt for good red hardness. CPM REX T15 is ideal for cutting difficult to machine materials where high frictional heating is encountered. Typical Chemistry Carbon 1.60% Manganese 0.30% (0.70%)* Silicon 0.30% Chromium 4.00% Vanadium 4.90% Tungsten 12.00% Cobalt 5.00% Sulfur 0.06% (0.22%)* Typical Applications Broaches Milling Cutters End Mills Spade Drills Form Tools Shaper Cutters Gear Hobs Taps *The addition of .20/.25 S in larger diameter rounds (e.g. 2-9/16" and over) provides a uniform dispersion of small sulfides throughout the structure, resulting in machinability and grindability benefits with no deleterious effect on toughness. Annealed Hardness: BH 245/275. Machinability in the annealed condition is approximately 20% of W1 Tool Steel (1%C). Thermal Treatments Critical Temperature: 1550F(845C) Forging: 2000-2100F(1095-1150C). Do not forge below 1700F(925C). Slow cool after forging. Annealing: 1600F(870C), hold 2 hours, slow cool 30F(15C)/ hour maximum to 1000F(540C), then air or furnace cool. Hardness BHN 245/275. Stress Relieving (After machining): (After machining) 1100-1300F(595-740C), hold 2 hours and air or furnace cool. Straightening: Best done warm 400-800F(200-430C). Hardening: (Salt, vacuum or atmosphere) Preheat: 1500-1550F(820-845C), equalize. A second preheat at 1800-1900F(1010-1040C) is suggested for vacuum or atmosphere hardening. High Heat: 2125-2250F(1165-1235C). Standard recommendation to achieve Rc 66-68 is to use 2225-2250F(1220-1235C). Quench: Salt, oil or atmosphere quench to 1000-1100F(540-595C), equalize, then air cool to below 125F(50C) or hand warm. The vacuum or atmosphere quench rate through 1850-1300F(1010-705C) range is critical to achieve optimum heat treat response. Temper: 1000F(540C) minimum recommended. Triple tempering required. (See table). Stress-relieving (Hardened parts): (Hardened parts) Temper 30F(15C) below original tempering temperature or 1000F(540C) minimum. Size Change During Hardening Hardening Temp.
