Stainless Steel 301 vs SUS836L

Stainless Steel · grade comparison

Stainless Steel 301 and SUS836L are both stainless steel grades. 301 is the stronger of the two: yield strength 570 MPa (82.7 ksi) against 320 MPa (46.4 ksi) for SUS836L, about 78% more; tensile strength follows at 900 MPa (131 ksi) vs 640 MPa (92.8 ksi). In exchange, SUS836L is the more ductile: elongation 45% versus 25% for 301, and 301 is harder (270 HB vs 180 HB). 301 conducts heat better (16.2 W/m·K vs 12 W/m·K). On the shop floor, 301 machines more easily (fair vs poor) and 301 sits in a lower cost tier (premium, $$$) than SUS836L (high, $$$$).

301Choose it when strength drives the design, or when the part is machined in volume.

SUS836LChoose it when the part is bent, formed or impact-loaded.

301 vs SUS836L — frequently asked

Is 301 stronger than SUS836L?

Yes. 301 has a typical yield strength of 570 MPa (82.7 ksi) against 320 MPa (46.4 ksi) for SUS836L — about 78% more. Tensile strength is 900 MPa (131 ksi) vs 640 MPa (92.8 ksi).

Which is cheaper, 301 or SUS836L?

301 is the lower-cost material: it sits in the premium tier ($$$) while SUS836L is high ($$$$). 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, 301 or SUS836L?

301. Its machinability rates fair (35/100) against poor (25/100) for SUS836L; for welding the order is SUS836L first (very good, 70/100) then 301 (good, 65/100).
