Stainless Steel 1.4837 vs HL
Stainless Steel · grade comparison
Stainless Steel 1.4837 and HL are both stainless steel grades. HL is the stronger of the two: yield strength 340 MPa (49.3 ksi) against 265 MPa (38.4 ksi) for 1.4837, about 28% more; tensile strength follows at 565 MPa (81.9 ksi) vs 520 MPa (75.4 ksi). HL is the more ductile: elongation 15% versus 12% for 1.4837. HL runs hotter in service (1,150°C vs 1,050°C continuous). On the shop floor, 1.4837 sits in a lower cost tier (premium, $$$) than HL (high, $$$$).
1.4837Choose it when cost is the deciding factor.
HLChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.
1.4837 vs HL: 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 HL — frequently asked
Is HL stronger than 1.4837?
Yes. HL has a typical yield strength of 340 MPa (49.3 ksi) against 265 MPa (38.4 ksi) for 1.4837 — about 28% more. Tensile strength is 565 MPa (81.9 ksi) vs 520 MPa (75.4 ksi).
Which is cheaper, 1.4837 or HL?
1.4837 is the lower-cost material: it sits in the premium tier ($$$) while HL is high ($$$$). Part price depends far more on geometry, tolerance and quantity than on raw stock — upload a CAD file for a live quote.
Which is easier to machine, 1.4837 or HL?
HL, by a small margin. Both rate poor for machinability — 28/100 against 22/100 for 1.4837.
