Steel H11 As Printed vs H11 Q&T

Steel · H11 temper comparison

H11 As Printed and H11 Q&T are two conditions of the same steel grade, H11: As Printed (as built (as printed)) versus Q&T (quenched and tempered). The chemistry is identical, so every difference below comes from the condition. H11 As Printed is the stronger of the two: yield strength 1,450 MPa (210 ksi) against 1,300 MPa (189 ksi) for H11 Q&T, about 12% more; tensile strength follows at 1,750 MPa (254 ksi) vs 1,550 MPa (225 ksi). In exchange, H11 Q&T is the more ductile: elongation 12% versus 3% for H11 As Printed, and H11 As Printed is harder (550 HV vs 460 HV). On the shop floor, H11 Q&T machines more easily (30 vs 20 out of 100).

H11 As Printed vs H11 Q&T — frequently asked

Is H11 As Printed stronger than H11 Q&T?

Yes. H11 As Printed has a typical yield strength of 1,450 MPa (210 ksi) against 1,300 MPa (189 ksi) for H11 Q&T — about 12% more. Tensile strength is 1,750 MPa (254 ksi) vs 1,550 MPa (225 ksi).

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

Annealed is the default H11 condition in the FabDigit quote flow (neither As Printed 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, H11 As Printed or H11 Q&T?

H11 Q&T, by a small margin. Both rate poor for machinability — 30/100 against 20/100 for H11 As Printed; for welding the order is H11 As Printed first (fair, 35/100) then H11 Q&T (poor, 30/100).
