Steel 1132-IH vs 1132 QT-22-26HRC

Steel · 1132 temper comparison

1132-IH and 1132 QT-22-26HRC are two conditions of the same steel grade, 1132: IH (induction hardened) versus QT-22-26HRC. The chemistry is identical, so every difference below comes from the condition. 1132 QT-22-26HRC is the stronger of the two: yield strength 650 MPa (94.3 ksi) against 560 MPa (81.2 ksi) for 1132-IH, about 16% more; tensile strength follows at 820 MPa (119 ksi) vs 700 MPa (102 ksi). 1132 QT-22-26HRC is the more ductile: elongation 17% versus 10% for 1132-IH, and 1132-IH is harder (530 HB vs 248 HB). 1132 QT-22-26HRC runs hotter in service (425°C vs 200°C continuous). On the shop floor, 1132 QT-22-26HRC machines more easily (good vs poor) and 1132 QT-22-26HRC welds better (poor vs not recommended).

1132 QT-22-26HRCChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.

1132-IH vs 1132 QT-22-26HRC — frequently asked

Is 1132 QT-22-26HRC stronger than 1132-IH?

Yes. 1132 QT-22-26HRC has a typical yield strength of 650 MPa (94.3 ksi) against 560 MPa (81.2 ksi) for 1132-IH — about 16% more. Tensile strength is 820 MPa (119 ksi) vs 700 MPa (102 ksi).

Which condition does FabDigit quote by default, IH or QT-22-26HRC?

CD is the default 1132 condition in the FabDigit quote flow (neither IH nor QT-22-26HRC). 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, 1132-IH or 1132 QT-22-26HRC?

1132 QT-22-26HRC. Its machinability rates good (62/100) against poor (25/100) for 1132-IH; for welding the order is 1132 QT-22-26HRC first (poor, 20/100) then 1132-IH (not recommended, 5/100).
