Stainless Steel 1.4837 vs CG6MMN
Stainless Steel · grade comparison
Stainless Steel 1.4837 and CG6MMN are both stainless steel grades. CG6MMN is the stronger of the two: yield strength 350 MPa (50.8 ksi) against 265 MPa (38.4 ksi) for 1.4837, about 32% more; tensile strength follows at 655 MPa (95 ksi) vs 520 MPa (75.4 ksi). CG6MMN is the more ductile: elongation 40% versus 12% for 1.4837. 1.4837 runs hotter in service (1,050°C vs 650°C continuous) and 1.4837 conducts heat better (14.5 W/m·K vs 13 W/m·K). On the shop floor, CG6MMN welds better (very good vs fair) and 1.4837 sits in a lower cost tier (premium, $$$) than CG6MMN (high, $$$$).
1.4837Choose it when the part sees heat, or when cost is the deciding factor.
CG6MMNChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.
1.4837 vs CG6MMN: 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 CG6MMN — frequently asked
Is CG6MMN stronger than 1.4837?
Yes. CG6MMN has a typical yield strength of 350 MPa (50.8 ksi) against 265 MPa (38.4 ksi) for 1.4837 — about 32% more. Tensile strength is 655 MPa (95 ksi) vs 520 MPa (75.4 ksi).
Which is cheaper, 1.4837 or CG6MMN?
1.4837 is the lower-cost material: it sits in the premium tier ($$$) while CG6MMN is high ($$$$). 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 CG6MMN?
CG6MMN, by a small margin. Both rate poor for machinability — 30/100 against 22/100 for 1.4837; for welding the order is CG6MMN first (very good, 70/100) then 1.4837 (fair, 40/100).
