Stainless Steel 414 vs 416

Stainless Steel · grade comparison

Stainless Steel 414 and 416 are both stainless steel grades. 414 is the stronger of the two: yield strength 620 MPa (89.9 ksi) against 275 MPa (39.9 ksi) for 416, about 125% more; tensile strength follows at 795 MPa (115 ksi) vs 515 MPa (74.7 ksi). In exchange, 416 is the more ductile: elongation 30% versus 20% for 414, and 414 is harder (235 HB vs 155 HB). 416 conducts electricity better (3 % IACS vs 2.5 % IACS). On the shop floor, 416 machines more easily (very good vs fair) and 414 welds better (fair vs poor).

414Choose it when strength drives the design, or when it will be welded.

416Choose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.

414 vs 416 — frequently asked

Is 414 stronger than 416?

Yes. 414 has a typical yield strength of 620 MPa (89.9 ksi) against 275 MPa (39.9 ksi) for 416 — about 125% more. Tensile strength is 795 MPa (115 ksi) vs 515 MPa (74.7 ksi).

Which is cheaper, 414 or 416?

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 is easier to machine, 414 or 416?

416. Its machinability rates very good (80/100) against fair (45/100) for 414; for welding the order is 414 first (fair, 38/100) then 416 (poor, 22/100).
