Stainless Steel 1.4710 vs CB30
Stainless Steel · grade comparison
Stainless Steel 1.4710 and CB30 are both stainless steel grades. CB30 is the stronger of the two: yield strength 415 MPa (60.2 ksi) against 290 MPa (42.1 ksi) for 1.4710, about 43% more; tensile strength follows at 655 MPa (95 ksi) vs 520 MPa (75.4 ksi). CB30 is the more ductile: elongation 15% versus 6% for 1.4710. 1.4710 runs hotter in service (850°C vs 400°C continuous) and 1.4710 conducts heat better (26 W/m·K vs 23 W/m·K).
1.4710Choose it when the part sees heat.
CB30Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
1.4710 vs CB30: 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.

1.4710 vs CB30 — frequently asked
Is CB30 stronger than 1.4710?
Yes. CB30 has a typical yield strength of 415 MPa (60.2 ksi) against 290 MPa (42.1 ksi) for 1.4710 — about 43% more. Tensile strength is 655 MPa (95 ksi) vs 520 MPa (75.4 ksi).
Which is cheaper, 1.4710 or CB30?
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.
When should I choose 1.4710 over CB30?
Pick 1.4710 when the part sees heat. Pick CB30 when strength drives the design, or when the part is bent, formed or impact-loaded.
