Stainless Steel X46Cr13 +A vs X46Cr13 H+T180-MAX
Stainless Steel · X46Cr13 temper comparison
X46Cr13 +A and X46Cr13 H+T180-MAX are two conditions of the same stainless steel grade, X46Cr13: +A (annealed) versus H+T180-MAX (hardened, sub-zero optional, tempered to maximum hardness). The chemistry is identical, so every difference below comes from the condition. X46Cr13 H+T180-MAX is the stronger of the two: yield strength 1,650 MPa (239 ksi) against 450 MPa (65.3 ksi) for X46Cr13 +A, about 3.7 times as much; tensile strength follows at 1,950 MPa (283 ksi) vs 750 MPa (109 ksi). In exchange, X46Cr13 +A is the more ductile: elongation 18% versus 1.5% for X46Cr13 H+T180-MAX, and X46Cr13 H+T180-MAX is harder (55 HRC vs 20 HRC). X46Cr13 +A runs hotter in service (400°C vs 180°C continuous). On the shop floor, X46Cr13 +A machines more easily (fair vs not recommended) and X46Cr13 +A welds better (poor vs not recommended).
X46Cr13 +AChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.

X46Cr13 +A vs X46Cr13 H+T180-MAX: 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.

X46Cr13 +A vs X46Cr13 H+T180-MAX — frequently asked
Is X46Cr13 H+T180-MAX stronger than X46Cr13 +A?
Yes. X46Cr13 H+T180-MAX has a typical yield strength of 1,650 MPa (239 ksi) against 450 MPa (65.3 ksi) for X46Cr13 +A — about 3.7 times as much. Tensile strength is 1,950 MPa (283 ksi) vs 750 MPa (109 ksi).
Which condition does FabDigit quote by default, +A or H+T180-MAX?
+A is the default X46Cr13 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, X46Cr13 +A or X46Cr13 H+T180-MAX?
X46Cr13 +A. Its machinability rates fair (40/100) against not recommended (8/100) for X46Cr13 H+T180-MAX; for welding the order is X46Cr13 +A first (poor, 25/100) then X46Cr13 H+T180-MAX (not recommended, 8/100).
