Stainless Steel 1.4837 vs HG10MNN
Stainless Steel · grade comparison
Stainless Steel 1.4837 and HG10MNN are both stainless steel grades. HG10MNN is the stronger of the two: yield strength 290 MPa (42.1 ksi) against 265 MPa (38.4 ksi) for 1.4837, about 9% more; tensile strength follows at 585 MPa (84.8 ksi) vs 520 MPa (75.4 ksi). HG10MNN is the more ductile: elongation 35% versus 12% for 1.4837, and 1.4837 is harder (190 HB vs 175 HB). 1.4837 runs hotter in service (1,050°C vs 900°C continuous). On the shop floor, HG10MNN machines more easily (32 vs 22 out of 100) and HG10MNN welds better (good vs fair).

HG10MNNChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.
1.4837 vs HG10MNN: 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.

1.4837 vs HG10MNN — frequently asked
Is HG10MNN stronger than 1.4837?
Yes. HG10MNN has a typical yield strength of 290 MPa (42.1 ksi) against 265 MPa (38.4 ksi) for 1.4837 — about 9% more. Tensile strength is 585 MPa (84.8 ksi) vs 520 MPa (75.4 ksi).
Which is cheaper, 1.4837 or HG10MNN?
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, 1.4837 or HG10MNN?
HG10MNN, by a small margin. Both rate poor for machinability — 32/100 against 22/100 for 1.4837; for welding the order is HG10MNN first (good, 58/100) then 1.4837 (fair, 40/100).
