Stainless Steel 301 vs 316Ti

Stainless Steel · grade comparison

Stainless Steel 301 and 316Ti are both stainless steel grades, both corrosion resistant ss. 301 is the stronger of the two: yield strength 570 MPa (82.7 ksi) against 260 MPa (37.7 ksi) for 316Ti, about 119% more; tensile strength follows at 900 MPa (131 ksi) vs 580 MPa (84.1 ksi). In exchange, 316Ti is the more ductile: elongation 45% versus 25% for 301, and 301 is harder (270 HB vs 160 HB). 316Ti runs hotter in service (800°C vs 425°C continuous). On the shop floor, 316Ti welds better (excellent vs good).

301Choose it when strength drives the design.

316TiChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.

301 vs 316Ti — frequently asked

Is 301 stronger than 316Ti?

Yes. 301 has a typical yield strength of 570 MPa (82.7 ksi) against 260 MPa (37.7 ksi) for 316Ti — about 119% more. Tensile strength is 900 MPa (131 ksi) vs 580 MPa (84.1 ksi).

Which is cheaper, 301 or 316Ti?

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 welds better, 301 or 316Ti?

316Ti. Its weldability rates excellent (85/100) against good (65/100) for 301.
