Steel 1050-H14 vs 1050-HR

Steel · 1050 temper comparison

1050-H14 and 1050-HR are two conditions of the same steel grade, 1050: H14 (strain hardened, half hard) versus HR (hot rolled). The chemistry is identical, so every difference below comes from the condition. 1050-H14 is the stronger of the two: yield strength 660 MPa (95.7 ksi) against 340 MPa (49.3 ksi) for 1050-HR, about 94% more; tensile strength follows at 760 MPa (110 ksi) vs 620 MPa (89.9 ksi). In exchange, 1050-HR is the more ductile: elongation 15% versus 8% for 1050-H14, and 1050-H14 is harder (228 HB vs 179 HB). 1050-HR runs hotter in service (400°C vs 250°C continuous).

1050-H14Choose it when strength drives the design.

1050-HRChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.

1050-H14 vs 1050-HR — frequently asked

Is 1050-H14 stronger than 1050-HR?

Yes. 1050-H14 has a typical yield strength of 660 MPa (95.7 ksi) against 340 MPa (49.3 ksi) for 1050-HR — about 94% more. Tensile strength is 760 MPa (110 ksi) vs 620 MPa (89.9 ksi).

Which condition does FabDigit quote by default, H14 or HR?

HR is the default 1050 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 welds better, 1050-H14 or 1050-HR?

1050-HR. Its weldability rates poor (30/100) against poor (25/100) for 1050-H14.
