Chemical & Environmental2

Corrosion resistance is good (60/100), better than 99% of steel grades.

Corrosion ResistanceGood60/100
Chemical Resistance SummaryGood resistance to fresh water, food acids, sweat and mild atmospheric exposure when fully hardened and polished; pits in chlorides/seawater and is attacked by strong acids — corrosion resistance drops markedly if high-temperature (secondary hardening) tempering is used.

Sustainability4

Producing a kilogram of CPM S30V H&T + Cryo 60-61 HRC takes about 70 MJ of energy and emits 5.5 kg of CO₂ — more than 97% of steel grades. Typical recycled content is 25%.

Working with CPM S30V H&T + Cryo 60-61 HRC

Is CPM S30V easy to machine?

Machine only in the annealed state with rigid setups, low speeds and carbide or ceramic tooling; hardened parts require CBN/diamond grinding or EDM, and abundant coolant to avoid burn.

Can CPM S30V be welded?

Not recommended for structural joints; if unavoidable, preheat 200–260 °C, use matched or 410-type filler and temper immediately, expect cracking risk.

Can CPM S30V be formed, bent or molded?

Essentially non-formable cold; produce shapes by machining, waterjet or grinding of annealed stock, then harden.

What surface finishes work on CPM S30V?

Passivate after hardening, hand-finish or belt-grind to remove decarburized skin; takes a satin-to-mirror finish and accepts DLC/PVD or black-oxide coatings.

CPM S30V H&T + Cryo 60-61 HRC — frequently asked

What is CPM S30V H&T + Cryo 60-61 HRC used for?

CPM S30V H&T + Cryo 60-61 HRC is typically used for kitchen knife blades, tactical and folding knife blades, hunting and outdoor blades, industrial slitting and trimming knives, food-processing cutting blades and corrosion-exposed wear inserts. In short: premium powder-metal blade.

What is the yield strength of CPM S30V H&T + Cryo 60-61 HRC?

CPM S30V H&T + Cryo 60-61 HRC has a typical yield strength of 1,950 MPa (283 ksi) and a tensile strength of 2,200 MPa (319 ksi) — stronger than 100% of steel grades. Strength varies by condition: see the 5 listed tempers.

Is CPM S30V H&T + Cryo 60-61 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 carbide or ceramic tooling; hardened parts require CBN/diamond grinding or EDM, and abundant coolant to avoid burn.

Can CPM S30V H&T + Cryo 60-61 HRC be welded?

Not readily — weldability is rated not recommended (4/100). Not recommended for structural joints; if unavoidable, preheat 200–260 °C, use matched or 410-type filler and temper immediately, expect cracking risk.

What surface finishes work on CPM S30V H&T + Cryo 60-61 HRC?

Passivate after hardening, hand-finish or belt-grind to remove decarburized skin; takes a satin-to-mirror finish and accepts DLC/PVD or black-oxide coatings.

Can CPM S30V H&T + Cryo 60-61 HRC be formed, bent or molded?

Essentially non-formable cold; produce shapes by machining, waterjet or grinding of annealed stock, then harden.

What is the maximum service temperature of CPM S30V H&T + Cryo 60-61 HRC?

CPM S30V H&T + Cryo 60-61 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 S30V H&T + Cryo 60-61 HRC?

Yes — CPM S30V H&T + Cryo 60-61 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.
