Stainless Steel S46910 1/2H vs S46910-FH
Stainless Steel · S46910 temper comparison
S46910 1/2H and S46910-FH are two conditions of the same stainless steel grade, S46910: 1/2H (half hard) 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 1,340 MPa (194 ksi) for S46910 1/2H, about 21% more; tensile strength follows at 1,720 MPa (249 ksi) vs 1,450 MPa (210 ksi). In exchange, S46910 1/2H is the more ductile: elongation 6% versus 4% for S46910-FH, and S46910-FH is harder (49 HRC vs 45 HRC).
S46910 1/2HChoose it when the part is bent, formed or impact-loaded.
S46910-FHChoose it when strength drives the design.
S46910 1/2H 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 1/2H vs S46910-FH — frequently asked
Is S46910-FH stronger than S46910 1/2H?
Yes. S46910-FH has a typical yield strength of 1,620 MPa (235 ksi) against 1,340 MPa (194 ksi) for S46910 1/2H — about 21% more. Tensile strength is 1,720 MPa (249 ksi) vs 1,450 MPa (210 ksi).
Which condition does FabDigit quote by default, 1/2H or FH?
FH+A is the default S46910 condition in the FabDigit quote flow (neither 1/2H 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 welds better, S46910 1/2H or S46910-FH?
S46910 1/2H. Its weldability rates good (55/100) against fair (50/100) for S46910-FH.
