Physical3
CF10 has a density of 7.75 g/cm³ (0.28 lb/in³), lighter than 65% of stainless steel grades. It melts at 1,400°C (2,552 °F).
Mechanical15
CF10 has a yield strength of 260 MPa (37.7 ksi) and a tensile strength of 530 MPa (76.9 ksi) — weaker than 84% of stainless steel grades. Elongation at break is 50% and the elastic modulus is 193 GPa (28 Msi).
Thermal6
CF10 is rated for continuous service to 700°C (1,292 °F). It conducts heat at 16.2 W/m·K (9.36 BTU/hr·ft·°F), better than 64% of stainless steel grades. Thermal expansion is 17 µm/m·K (9.44 µin/in·°F).
Electrical3
CF10 conducts electricity at 2.2 % IACS, worse than 61% of stainless steel grades.
Chemical & Environmental3
Corrosion resistance is good (60/100), worse than 58% of stainless steel grades.
Sustainability4
Producing a kilogram of CF10 takes about 55 MJ of energy and emits 4.5 kg of CO₂ — more than 50% of stainless steel grades. Typical recycled content is 75%.
Manufacturability8
CF10's machinability is fair (40/100, better than 72% of stainless steel grades); weldability good (55/100); formability poor (20/100).

Working with CF10
Is CF10 easy to machine?
Gummy and work-hardening like 304 — use rigid setups, positive-rake carbide, heavy feeds, flood coolant, and avoid dwelling; expect ~45% of AISI 1212.
Can CF10 be welded?
Weld with 308/308L filler and low heat input; ferrite resists hot cracking, but the 0.04–0.10% C makes post-weld solution annealing advisable for corrosive service.
Can CF10 be formed, bent or molded?
Sand or investment cast with good fluidity and 2.0–2.3% shrink allowance; delta ferrite limits hot tearing but keep sections uniform and feed heavy junctions.
CF10 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.
| Element | Spec limit (wt %) | Nominal |
|---|---|---|
| Chigher than CF3/CF8; sensitization risk | 0.04 – 0.1 | 0.07 |
| Mn | ≤ 1.5 | 1 |
| Si | ≤ 2 | 1.2 |
| P | ≤ 0.04 | 0.03 |
| S | ≤ 0.04 | 0.02 |
| Cr | 18 – 21 | 19.5 |
| Ni | 8 – 11 | 9.5 |
| MoA351 residual limit where Mo is not intentionally added | ≤ 0.5 | 0.2 |
| Fe | balance |
What surface finishes work on CF10?
Passivate (ASTM A967 nitric or citric) or electropolish after machining; shot blast and pickle to remove casting scale — no anodizing on ferrous alloys.

CF10 — frequently asked
What is CF10 used for?
CF10 is typically used for valve bodies, pump parts and general corrosion-resistant castings. In short: higher-carbon CF8 variant; ductile general-purpose casting; 700 °C service limit.
What is the yield strength of CF10?
CF10 has a typical yield strength of 260 MPa (37.7 ksi) and a tensile strength of 530 MPa (76.9 ksi) — weaker than 84% of stainless steel grades. Strength varies by condition: see the 3 listed tempers.
Is CF10 easy to machine?
Not especially — machinability is rated fair (40/100, better than 72% of stainless steel grades). Gummy and work-hardening like 304 — use rigid setups, positive-rake carbide, heavy feeds, flood coolant, and avoid dwelling; expect ~45% of AISI 1212.
Can CF10 be welded?
Yes — weldability is rated good (55/100). Weld with 308/308L filler and low heat input; ferrite resists hot cracking, but the 0.04–0.10% C makes post-weld solution annealing advisable for corrosive service.
What surface finishes work on CF10?

Sand or investment cast with good fluidity and 2.0–2.3% shrink allowance; delta ferrite limits hot tearing but keep sections uniform and feed heavy junctions.
What is the maximum service temperature of CF10?
CF10 is rated for continuous use to about 700°C (1,292 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between CF10-SA and CF10 CENT-SA?
SA is the default condition — standard supply condition for all CF10 pressure-containing castings; maximum ductility and corrosion resistance. CENT-SA: choose for pipe and cylindrical sections where the denser, directionally solidified structure raises strength and soundness. Yield strength is 260 MPa in SA versus 275 MPa in CENT-SA.
