Stainless Steel S41041 1/4H vs S41041 Q&T
Stainless Steel · S41041 temper comparison
S41041 1/4H and S41041 Q&T are two conditions of the same stainless steel grade, S41041: 1/4H (quarter hard) versus Q&T (quenched and tempered). The chemistry is identical, so every difference below comes from the condition. S41041 Q&T is the stronger of the two: yield strength 590 MPa (85.6 ksi) against 500 MPa (72.5 ksi) for S41041 1/4H, about 18% more; tensile strength follows at 760 MPa (110 ksi) vs 620 MPa (89.9 ksi). S41041 Q&T is the more ductile: elongation 18% versus 12% for S41041 1/4H, and S41041 Q&T is harder (245 HB vs 210 HB). S41041 Q&T runs hotter in service (650°C vs 400°C continuous).
S41041 Q&TChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.
S41041 1/4H vs S41041 Q&T: 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.

S41041 1/4H vs S41041 Q&T — frequently asked
Is S41041 Q&T stronger than S41041 1/4H?
Yes. S41041 Q&T has a typical yield strength of 590 MPa (85.6 ksi) against 500 MPa (72.5 ksi) for S41041 1/4H — about 18% more. Tensile strength is 760 MPa (110 ksi) vs 620 MPa (89.9 ksi).
Which condition does FabDigit quote by default, 1/4H or Q&T?
Annealed is the default S41041 condition in the FabDigit quote flow (neither 1/4H nor Q&T). 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.
When should I choose S41041 1/4H over S41041 Q&T?
Pick S41041 Q&T when strength drives the design, or when the part is bent, formed or impact-loaded.
