Stainless Steel S46910-A vs S46910-FH
Stainless Steel · S46910 temper comparison
S46910-A and S46910-FH are two conditions of the same stainless steel grade, S46910: A (solution annealed) versus FH (full hard). The chemistry is identical, so every difference below comes from the condition. S46910-FH is the stronger of the two: yield strength 1,620 MPa (235 ksi) against 830 MPa (120 ksi) for S46910-A, about 95% more; tensile strength follows at 1,720 MPa (249 ksi) vs 1,030 MPa (149 ksi). In exchange, S46910-A is the more ductile: elongation 16% versus 4% for S46910-FH, and S46910-FH is harder (49 HRC vs 33 HRC). On the shop floor, S46910-A machines more easily (fair vs poor) and S46910-A welds better (good vs fair).
S46910-AChoose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.
S46910-FHChoose it when strength drives the design.
S46910-A vs S46910-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.

S46910-A vs S46910-FH — frequently asked
Is S46910-FH stronger than S46910-A?
Yes. S46910-FH has a typical yield strength of 1,620 MPa (235 ksi) against 830 MPa (120 ksi) for S46910-A — about 95% more. Tensile strength is 1,720 MPa (249 ksi) vs 1,030 MPa (149 ksi).
Which condition does FabDigit quote by default, A or FH?
FH+A is the default S46910 condition in the FabDigit quote flow (neither A 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, S46910-A or S46910-FH?
S46910-A. Its machinability rates fair (38/100) against poor (26/100) for S46910-FH; for welding the order is S46910-A first (good, 65/100) then S46910-FH (fair, 50/100).
