Stainless Steel 1.4107 vs 1.4710
Stainless Steel · grade comparison
Stainless Steel 1.4107 and 1.4710 are both stainless steel grades. 1.4107 is the stronger of the two: yield strength 400 MPa (58 ksi) against 290 MPa (42.1 ksi) for 1.4710, about 38% more; tensile strength follows at 610 MPa (88.5 ksi) vs 520 MPa (75.4 ksi). 1.4107 is the more ductile: elongation 22% versus 6% for 1.4710, and 1.4710 is harder (205 HB vs 185 HB). 1.4710 runs hotter in service (850°C vs 400°C continuous). On the shop floor, 1.4107 welds better (very good vs poor).
1.4107Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
1.4710Choose it when the part sees heat.
1.4107 vs 1.4710: 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.

1.4107 vs 1.4710 — frequently asked
Is 1.4107 stronger than 1.4710?
Yes. 1.4107 has a typical yield strength of 400 MPa (58 ksi) against 290 MPa (42.1 ksi) for 1.4710 — about 38% more. Tensile strength is 610 MPa (88.5 ksi) vs 520 MPa (75.4 ksi).
Which is cheaper, 1.4107 or 1.4710?
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, 1.4107 or 1.4710?
1.4107, by a small margin. Both rate fair for machinability — 45/100 against 40/100 for 1.4710; for welding the order is 1.4107 first (very good, 70/100) then 1.4710 (poor, 30/100).
