Stainless Steel 317LN Cold Drawn vs 317LN Full Hard

Stainless Steel · 317LN temper comparison

317LN Cold Drawn and 317LN Full Hard are two conditions of the same stainless steel grade, 317LN: Cold Drawn versus Full Hard. The chemistry is identical, so every difference below comes from the condition. 317LN Full Hard is the stronger of the two: yield strength 1,000 MPa (145 ksi) against 500 MPa (72.5 ksi) for 317LN Cold Drawn, about 100% more; tensile strength follows at 1,280 MPa (186 ksi) vs 720 MPa (104 ksi). In exchange, 317LN Cold Drawn is the more ductile: elongation 30% versus 6% for 317LN Full Hard, and 317LN Full Hard is harder (370 HB vs 220 HB). 317LN Cold Drawn runs hotter in service (400°C vs 300°C continuous). On the shop floor, 317LN Cold Drawn machines more easily (fair vs poor) and 317LN Cold Drawn welds better (very good vs good).

317LN Cold DrawnChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.

317LN Full HardChoose it when strength drives the design.

317LN Cold Drawn vs 317LN Full Hard — frequently asked

Is 317LN Full Hard stronger than 317LN Cold Drawn?

Yes. 317LN Full Hard has a typical yield strength of 1,000 MPa (145 ksi) against 500 MPa (72.5 ksi) for 317LN Cold Drawn — about 100% more. Tensile strength is 1,280 MPa (186 ksi) vs 720 MPa (104 ksi).

Which condition does FabDigit quote by default, Cold Drawn or Full Hard?

Annealed is the default 317LN condition in the FabDigit quote flow (neither Cold Drawn nor Full Hard). The other condition is available on request or by drawing note — specify it in the material field or the part notes and the quote is priced for it.

Which is easier to machine, 317LN Cold Drawn or 317LN Full Hard?

317LN Cold Drawn. Its machinability rates fair (38/100) against poor (25/100) for 317LN Full Hard; for welding the order is 317LN Cold Drawn first (very good, 82/100) then 317LN Full Hard (good, 60/100).
