Stainless Steel CB30 vs CC50
Stainless Steel · grade comparison
Stainless Steel CB30 and CC50 are both stainless steel grades. CB30 is the stronger of the two: yield strength 415 MPa (60.2 ksi) against 275 MPa (39.9 ksi) for CC50, about 51% more; tensile strength follows at 655 MPa (95 ksi) vs 480 MPa (69.6 ksi). CB30 is the more ductile: elongation 15% versus 10% for CC50, and CC50 is harder (210 HB vs 195 HB). CC50 runs hotter in service (1,090°C vs 400°C continuous) and CB30 conducts heat better (23 W/m·K vs 20.5 W/m·K).
CB30Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
CC50Choose it when the part sees heat.
CB30 vs CC50: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all stainless steel grades in the FabDigit library; each bar is drawn as a share of that.
- The better value (by the usual engineering direction) is in bold. Rows with no direction — density, thermal conductivity — have no bold.
- Values are typical room-temperature figures for the condition named on each card.
- Confirm against the certified mill or resin datasheet before design release.

CB30 vs CC50 — frequently asked
Is CB30 stronger than CC50?
Yes. CB30 has a typical yield strength of 415 MPa (60.2 ksi) against 275 MPa (39.9 ksi) for CC50 — about 51% more. Tensile strength is 655 MPa (95 ksi) vs 480 MPa (69.6 ksi).
Which is cheaper, CB30 or CC50?
Both sit in the same relative cost tier ($$$, premium); the part price will be decided by machining time, tolerance and quantity rather than by the material.
Which is easier to machine, CB30 or CC50?
CB30, by a small margin. Both rate fair for machinability — 42/100 against 35/100 for CC50.
