Stainless Steel S46910-A vs S46910 FH+A
Stainless Steel · S46910 temper comparison
S46910-A and S46910 FH+A are two conditions of the same stainless steel grade, S46910: A (solution annealed) versus FH+A (FH + Aged). The chemistry is identical, so every difference below comes from the condition. S46910 FH+A is the stronger of the two: yield strength 2,000 MPa (290 ksi) against 830 MPa (120 ksi) for S46910-A, about 141% more; tensile strength follows at 2,070 MPa (300 ksi) vs 1,030 MPa (149 ksi). In exchange, S46910-A is the more ductile: elongation 16% versus 6% for S46910 FH+A, and S46910 FH+A is harder (55 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 FH+AChoose it when strength drives the design.
S46910-A vs S46910 FH+A: 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+A — frequently asked
Is S46910 FH+A stronger than S46910-A?
Yes. S46910 FH+A has a typical yield strength of 2,000 MPa (290 ksi) against 830 MPa (120 ksi) for S46910-A — about 141% more. Tensile strength is 2,070 MPa (300 ksi) vs 1,030 MPa (149 ksi).
Which condition does FabDigit quote by default, A or FH+A?
FH+A is the default S46910 condition in the FabDigit quote flow. 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+A?
S46910-A. Its machinability rates fair (38/100) against poor (22/100) for S46910 FH+A; for welding the order is S46910-A first (good, 65/100) then S46910 FH+A (fair, 45/100).
