Stainless Steel X20Cr13 +AR vs X20Cr13 H+T200
Stainless Steel · X20Cr13 temper comparison
X20Cr13 +AR and X20Cr13 H+T200 are two conditions of the same stainless steel grade, X20Cr13: +AR (hot rolled) versus H+T200 (hardened ~1020 °C, tempered ~200 °C). The chemistry is identical, so every difference below comes from the condition. X20Cr13 H+T200 is the stronger of the two: yield strength 1,400 MPa (203 ksi) against 520 MPa (75.4 ksi) for X20Cr13 +AR, about 169% more; tensile strength follows at 1,720 MPa (249 ksi) vs 820 MPa (119 ksi). In exchange, X20Cr13 +AR is the more ductile: elongation 15% versus 4% for X20Cr13 H+T200, and X20Cr13 +AR is harder (250 HB vs 200 HB). X20Cr13 +AR runs hotter in service (400°C vs 200°C continuous). On the shop floor, X20Cr13 +AR machines more easily (fair vs poor).
X20Cr13 +ARChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
X20Cr13 H+T200Choose it when strength drives the design.
X20Cr13 +AR vs X20Cr13 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.

X20Cr13 +AR vs X20Cr13 H+T200 — frequently asked
Is X20Cr13 H+T200 stronger than X20Cr13 +AR?
Yes. X20Cr13 H+T200 has a typical yield strength of 1,400 MPa (203 ksi) against 520 MPa (75.4 ksi) for X20Cr13 +AR — about 169% more. Tensile strength is 1,720 MPa (249 ksi) vs 820 MPa (119 ksi).
Which condition does FabDigit quote by default, +AR or H+T200?
+A is the default X20Cr13 condition in the FabDigit quote flow (neither +AR nor H+T200). 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, X20Cr13 +AR or X20Cr13 H+T200?
X20Cr13 +AR. Its machinability rates fair (42/100) against poor (18/100) for X20Cr13 H+T200.
