Stainless Steel SUS836L-CD vs SUS836L-FH
Stainless Steel · SUS836L temper comparison
SUS836L-CD and SUS836L-FH are two conditions of the same stainless steel grade, SUS836L: CD (cold drawn) versus FH (full hard). The chemistry is identical, so every difference below comes from the condition. SUS836L-FH is the stronger of the two: yield strength 950 MPa (138 ksi) against 520 MPa (75.4 ksi) for SUS836L-CD, about 83% more; tensile strength follows at 1,150 MPa (167 ksi) vs 760 MPa (110 ksi). In exchange, SUS836L-CD is the more ductile: elongation 30% versus 8% for SUS836L-FH, and SUS836L-FH is harder (330 HB vs 230 HB). SUS836L-CD runs hotter in service (400°C vs 250°C continuous). On the shop floor, SUS836L-CD welds better (very good vs good).
SUS836L-CDChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
SUS836L-FHChoose it when strength drives the design.
SUS836L-CD vs SUS836L-FH: 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.

SUS836L-CD vs SUS836L-FH — frequently asked
Is SUS836L-FH stronger than SUS836L-CD?
Yes. SUS836L-FH has a typical yield strength of 950 MPa (138 ksi) against 520 MPa (75.4 ksi) for SUS836L-CD — about 83% more. Tensile strength is 1,150 MPa (167 ksi) vs 760 MPa (110 ksi).
Which condition does FabDigit quote by default, CD or FH?
SA is the default SUS836L condition in the FabDigit quote flow (neither CD nor FH). 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, SUS836L-CD or SUS836L-FH?
SUS836L-CD, by a small margin. Both rate poor for machinability — 30/100 against 22/100 for SUS836L-FH; for welding the order is SUS836L-CD first (very good, 70/100) then SUS836L-FH (good, 55/100).
