Working with CPM 10V H&T 62-64 HRC
Is CPM 10V easy to machine?
Machine only in the annealed state with rigid setups, low speeds and TiAlN-coated carbide or ceramic; grinding after hardening needs CBN or seeded-gel/SG alumina wheels because vanadium carbides outrank conventional Al₂O₃.
Can CPM 10V be welded?
Essentially a repair-only operation — preheat 450–500 °C, matching or 420-type filler, small beads, immediate temper at 25 °C below the last tempering temperature; cracking risk is high.
Can CPM 10V be formed, bent or molded?
No cold forming; hot work 950–1100 °C with slow controlled cooling and immediate anneal, then harden at 1010–1175 °C with plate quench or 5–6 bar gas quench and triple temper at 540 °C.
What surface finishes work on CPM 10V?
Not stainless — protect with black oxide, phosphate, oil, hard chrome or PVD (TiN/AlTiN/CrN); nitriding after temper further boosts surface wear resistance.
CPM 10V chemical composition (wt %)
Limits by weight percent from the governing specification, written the way the spec states them — a single maximum for impurities, a range for alloying elements, and the base element as balance. Nominal is the typical mid-range value.

CPM 10V H&T 62-64 HRC — frequently asked
What is CPM 10V H&T 62-64 HRC used for?
CPM 10V H&T 62-64 HRC is typically used for cold blanking and piercing dies, slitting knives, shredder and granulator blades, powder-compaction tooling, forming and coining punches and thread-rolling dies. In short: premium wear-resistant tool.
What is the yield strength of CPM 10V H&T 62-64 HRC?
CPM 10V H&T 62-64 HRC has a typical yield strength of 1,950 MPa (283 ksi) and a tensile strength of 2,100 MPa (305 ksi) — stronger than 100% of steel grades. Strength varies by condition: see the 5 listed tempers.
Is CPM 10V H&T 62-64 HRC easy to machine?
Not especially — machinability is rated not recommended (4/100, worse than 100% of steel grades). Machine only in the annealed state with rigid setups, low speeds and TiAlN-coated carbide or ceramic; grinding after hardening needs CBN or seeded-gel/SG alumina wheels because vanadium carbides outrank conventional Al₂O₃.
Can CPM 10V H&T 62-64 HRC be welded?
Not readily — weldability is rated not recommended (5/100). Essentially a repair-only operation — preheat 450–500 °C, matching or 420-type filler, small beads, immediate temper at 25 °C below the last tempering temperature; cracking risk is high.
What surface finishes work on CPM 10V H&T 62-64 HRC?
Not stainless — protect with black oxide, phosphate, oil, hard chrome or PVD (TiN/AlTiN/CrN); nitriding after temper further boosts surface wear resistance.
Can CPM 10V H&T 62-64 HRC be formed, bent or molded?
No cold forming; hot work 950–1100 °C with slow controlled cooling and immediate anneal, then harden at 1010–1175 °C with plate quench or 5–6 bar gas quench and triple temper at 540 °C.
What is the maximum service temperature of CPM 10V H&T 62-64 HRC?
CPM 10V H&T 62-64 HRC is rated for continuous use to about 500°C (932 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
Can FabDigit make parts in CPM 10V H&T 62-64 HRC?
Yes — CPM 10V H&T 62-64 HRC is available for CNC machining; every part is priced by an engineer rather than instantly. Upload a STEP file to get a price and a DFM check.
