Steel 1074 Normalized vs 1074 Q&T

Steel · 1074 temper comparison

1074 Normalized and 1074 Q&T are two conditions of the same steel grade, 1074: Normalized versus Q&T (quenched and tempered). The chemistry is identical, so every difference below comes from the condition. 1074 Q&T is the stronger of the two: yield strength 1,150 MPa (167 ksi) against 435 MPa (63.1 ksi) for 1074 Normalized, about 164% more; tensile strength follows at 1,300 MPa (189 ksi) vs 760 MPa (110 ksi). In exchange, 1074 Normalized is the more ductile: elongation 12% versus 8% for 1074 Q&T, and 1074 Q&T is harder (388 HB vs 217 HB). 1074 Q&T runs hotter in service (300°C vs 250°C continuous). On the shop floor, 1074 Normalized machines more easily (fair vs poor) and 1074 Normalized welds better (25 vs 15 out of 100).

1074 NormalizedChoose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.

1074 Q&TChoose it when strength drives the design, or when the part sees heat.

1074 Normalized vs 1074 Q&T — frequently asked

Is 1074 Q&T stronger than 1074 Normalized?

Yes. 1074 Q&T has a typical yield strength of 1,150 MPa (167 ksi) against 435 MPa (63.1 ksi) for 1074 Normalized — about 164% more. Tensile strength is 1,300 MPa (189 ksi) vs 760 MPa (110 ksi).

Which condition does FabDigit quote by default, Normalized or Q&T?

HR is the default 1074 condition in the FabDigit quote flow (neither Normalized nor Q&T). 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, 1074 Normalized or 1074 Q&T?

1074 Normalized. Its machinability rates fair (38/100) against poor (22/100) for 1074 Q&T; for welding the order is 1074 Normalized first (poor, 25/100) then 1074 Q&T (poor, 15/100).
