Stainless Steel 1.4710 vs HC
Stainless Steel · grade comparison
Stainless Steel 1.4710 and HC are both stainless steel grades. HC is the stronger of the two: yield strength 450 MPa (65.3 ksi) against 290 MPa (42.1 ksi) for 1.4710, about 55% more; tensile strength follows at 690 MPa (100 ksi) vs 520 MPa (75.4 ksi). HC is the more ductile: elongation 12% versus 6% for 1.4710. HC runs hotter in service (1,090°C vs 850°C continuous) and 1.4710 conducts heat better (26 W/m·K vs 21 W/m·K).
HCChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.
1.4710 vs HC: 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 HC — frequently asked
Is HC stronger than 1.4710?
Yes. HC has a typical yield strength of 450 MPa (65.3 ksi) against 290 MPa (42.1 ksi) for 1.4710 — about 55% more. Tensile strength is 690 MPa (100 ksi) vs 520 MPa (75.4 ksi).
Which is cheaper, 1.4710 or HC?
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, 1.4710 or HC?
1.4710. Its machinability rates fair (40/100) against poor (32/100) for HC.
