Stainless Steel X46Cr13 +A vs X46Cr13 H+T200
Stainless Steel · X46Cr13 temper comparison
X46Cr13 +A and X46Cr13 H+T200 are two conditions of the same stainless steel grade, X46Cr13: +A (annealed) versus H+T200 (hardened and low-temperature tempered). The chemistry is identical, so every difference below comes from the condition. X46Cr13 H+T200 is the stronger of the two: yield strength 1,450 MPa (210 ksi) against 450 MPa (65.3 ksi) for X46Cr13 +A, about 3.2 times as much; tensile strength follows at 1,750 MPa (254 ksi) vs 750 MPa (109 ksi). In exchange, X46Cr13 +A is the more ductile: elongation 18% versus 3% for X46Cr13 H+T200, and X46Cr13 H+T200 is harder (480 HB vs 220 HB). X46Cr13 +A runs hotter in service (400°C vs 200°C continuous). On the shop floor, X46Cr13 +A machines more easily (fair vs poor) 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+T200: 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+T200 — frequently asked
Is X46Cr13 H+T200 stronger than X46Cr13 +A?
Yes. X46Cr13 H+T200 has a typical yield strength of 1,450 MPa (210 ksi) against 450 MPa (65.3 ksi) for X46Cr13 +A — about 3.2 times as much. Tensile strength is 1,750 MPa (254 ksi) vs 750 MPa (109 ksi).
Which condition does FabDigit quote by default, +A or H+T200?
+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+T200?
X46Cr13 +A. Its machinability rates fair (40/100) against poor (15/100) for X46Cr13 H+T200; for welding the order is X46Cr13 +A first (poor, 25/100) then X46Cr13 H+T200 (not recommended, 10/100).
