Stainless Steel 1.4436 vs 301
Stainless Steel · grade comparison
Stainless Steel 1.4436 and 301 are both stainless steel grades. 301 is the stronger of the two: yield strength 570 MPa (82.7 ksi) against 270 MPa (39.2 ksi) for 1.4436, about 111% more; tensile strength follows at 900 MPa (131 ksi) vs 590 MPa (85.6 ksi). In exchange, 1.4436 is the more ductile: elongation 50% versus 25% for 301, and 301 is harder (270 HB vs 150 HB). 1.4436 runs hotter in service (870°C vs 425°C continuous). On the shop floor, 1.4436 welds better (very good vs good) and 1.4436 sits in a lower cost tier (standard, $$) than 301 (premium, $$$).
1.4436Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
301Choose it when strength drives the design.
1.4436 vs 301: 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.
