Stainless Steel 1.4630 2H vs 1.4630-A
Stainless Steel · 1.4630 temper comparison
1.4630 2H and 1.4630-A are two conditions of the same stainless steel grade, 1.4630: 2H (cold worked / temper rolled) versus A (solution annealed). The chemistry is identical, so every difference below comes from the condition. 1.4630 2H is the stronger of the two: yield strength 460 MPa (66.7 ksi) against 300 MPa (43.5 ksi) for 1.4630-A, about 53% more; tensile strength follows at 560 MPa (81.2 ksi) vs 460 MPa (66.7 ksi). In exchange, 1.4630-A is the more ductile: elongation 28% versus 14% for 1.4630 2H, and 1.4630 2H is harder (195 HB vs 155 HB). 1.4630-A runs hotter in service (850°C vs 400°C continuous).

1.4630 2H vs 1.4630-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.

1.4630 2H vs 1.4630-A — frequently asked
Is 1.4630 2H stronger than 1.4630-A?
Yes. 1.4630 2H has a typical yield strength of 460 MPa (66.7 ksi) against 300 MPa (43.5 ksi) for 1.4630-A — about 53% more. Tensile strength is 560 MPa (81.2 ksi) vs 460 MPa (66.7 ksi).
Which condition does FabDigit quote by default, 2H or A?
A is the default 1.4630 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, 1.4630 2H or 1.4630-A?
1.4630 2H, by a small margin. Both rate good for machinability — 60/100 against 55/100 for 1.4630-A; for welding the order is 1.4630-A first (very good, 80/100) then 1.4630 2H (very good, 75/100).
