Working with CPM 3V HT 60-62 HRC
Is CPM 3V easy to machine?
Machine only in the annealed state with rigid setups, carbide or coated carbide tooling, low SFM and heavy positive rake; grinding of hardened parts needs SG/CBN wheels because of the 2.75% V carbides.
Can CPM 3V be welded?
Not intended for structural welding; repair-weld with matching or tool-steel filler at 400–500 °C preheat followed by an immediate temper to avoid HAZ cracking.
Can CPM 3V be formed, bent or molded?
Hot work at 1040–1120 °C with slow controlled cooling and full anneal; cold forming is impractical.
What surface finishes work on CPM 3V?
Polishes to a fine finish thanks to the uniform PM carbide structure; protect with oil, black oxide, phosphate or PVD/DLC coatings since it is not stainless — post-hardening cryogenic treatment plus double temper improves dimensional stability.
CPM 3V 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 3V HT 60-62 HRC — frequently asked
What is CPM 3V HT 60-62 HRC used for?
CPM 3V HT 60-62 HRC is typically used for cold work tooling, punches and shears. In short: premium tough wear tool.
What is the yield strength of CPM 3V HT 60-62 HRC?
CPM 3V HT 60-62 HRC has a typical yield strength of 2,050 MPa (297 ksi) and a tensile strength of 2,400 MPa (348 ksi) — stronger than 100% of steel grades. Strength varies by condition: see the 4 listed tempers.
Is CPM 3V HT 60-62 HRC easy to machine?
Not especially — machinability is rated not recommended (5/100, worse than 100% of steel grades). Machine only in the annealed state with rigid setups, carbide or coated carbide tooling, low SFM and heavy positive rake; grinding of hardened parts needs SG/CBN wheels because of the 2.75% V carbides.
Can CPM 3V HT 60-62 HRC be welded?
Not readily — weldability is rated not recommended (5/100). Not intended for structural welding; repair-weld with matching or tool-steel filler at 400–500 °C preheat followed by an immediate temper to avoid HAZ cracking.
What surface finishes work on CPM 3V HT 60-62 HRC?
Polishes to a fine finish thanks to the uniform PM carbide structure; protect with oil, black oxide, phosphate or PVD/DLC coatings since it is not stainless — post-hardening cryogenic treatment plus double temper improves dimensional stability.
Can CPM 3V HT 60-62 HRC be formed, bent or molded?
Hot work at 1040–1120 °C with slow controlled cooling and full anneal; cold forming is impractical.
What is the maximum service temperature of CPM 3V HT 60-62 HRC?
CPM 3V HT 60-62 HRC is rated for continuous use to about 200°C (392 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
Can FabDigit make parts in CPM 3V HT 60-62 HRC?
Yes — CPM 3V HT 60-62 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.
