Stainless Steel 2205 vs 316L
Stainless Steel · grade comparison
Stainless Steel 2205 and 316L are both stainless steel grades. 2205 is the stronger of the two: yield strength 540 MPa (78.3 ksi) against 290 MPa (42.1 ksi) for 316L, about 86% more; tensile strength follows at 790 MPa (115 ksi) vs 580 MPa (84.1 ksi). In exchange, 316L is the more ductile: elongation 50% versus 30% for 2205, and 2205 is harder (255 HB vs 150 HB). 316L runs hotter in service (800°C vs 300°C continuous). On the shop floor, 316L welds better (excellent vs very good) and 316L sits in a lower cost tier (high, $$$$) than 2205 (specialty, $$$$$).
2205Choose it when strength drives the design.
316LChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
2205 vs 316L: 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.

2205 vs 316L — frequently asked
Is 2205 stronger than 316L?
Yes. 2205 has a typical yield strength of 540 MPa (78.3 ksi) against 290 MPa (42.1 ksi) for 316L — about 86% more. Tensile strength is 790 MPa (115 ksi) vs 580 MPa (84.1 ksi).
Which is cheaper, 2205 or 316L?
316L is the lower-cost material: it sits in the high tier ($$$$) while 2205 is specialty ($$$$$). 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, 2205 or 316L?
316L. Its machinability rates fair (40/100) against poor (32/100) for 2205; for welding the order is 316L first (excellent, 90/100) then 2205 (very good, 78/100).
