Stainless Steel S43037 1/4H vs S43037 As Welded
Stainless Steel · S43037 temper comparison
S43037 1/4H and S43037 As Welded are two conditions of the same stainless steel grade, S43037: 1/4H (quarter hard) versus As Welded (as-welded deposit). The chemistry is identical, so every difference below comes from the condition. S43037 1/4H is the stronger of the two: yield strength 520 MPa (75.4 ksi) against 290 MPa (42.1 ksi) for S43037 As Welded, about 79% more; tensile strength follows at 620 MPa (89.9 ksi) vs 470 MPa (68.2 ksi). In exchange, S43037 As Welded is the more ductile: elongation 18% versus 10% for S43037 1/4H, and S43037 1/4H is harder (210 HB vs 155 HB). S43037 As Welded runs hotter in service (815°C vs 500°C continuous).

S43037 1/4H vs S43037 As Welded: 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.

S43037 1/4H vs S43037 As Welded — frequently asked
Is S43037 1/4H stronger than S43037 As Welded?
Yes. S43037 1/4H has a typical yield strength of 520 MPa (75.4 ksi) against 290 MPa (42.1 ksi) for S43037 As Welded — about 79% more. Tensile strength is 620 MPa (89.9 ksi) vs 470 MPa (68.2 ksi).
Which condition does FabDigit quote by default, 1/4H or As Welded?
Annealed 2B is the default S43037 condition in the FabDigit quote flow (neither 1/4H nor As Welded). 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, S43037 1/4H or S43037 As Welded?
S43037 1/4H, by a small margin. Both rate fair for machinability — 50/100 against 43/100 for S43037 As Welded.
