Steel G26CrMo4 +A vs G26CrMo4 +N

Steel · G26CrMo4 temper comparison

G26CrMo4 +A and G26CrMo4 +N are two conditions of the same steel grade, G26CrMo4: +A (annealed) versus +N (normalized). The chemistry is identical, so every difference below comes from the condition. G26CrMo4 +N is the stronger of the two: yield strength 320 MPa (46.4 ksi) against 300 MPa (43.5 ksi) for G26CrMo4 +A, about 7% more; tensile strength follows at 550 MPa (79.8 ksi) vs 520 MPa (75.4 ksi). G26CrMo4 +N is harder — 170 HB against 155 HB for G26CrMo4 +A — which matters for wear surfaces and threads.

G26CrMo4 +NChoose it when strength drives the design, or when surface hardness matters.

G26CrMo4 +A vs G26CrMo4 +N — frequently asked

Is G26CrMo4 +N stronger than G26CrMo4 +A?

Yes. G26CrMo4 +N has a typical yield strength of 320 MPa (46.4 ksi) against 300 MPa (43.5 ksi) for G26CrMo4 +A — about 7% more. Tensile strength is 550 MPa (79.8 ksi) vs 520 MPa (75.4 ksi).

Which condition does FabDigit quote by default, +A or +N?

+QT1 is the default G26CrMo4 condition in the FabDigit quote flow (neither +A nor +N). 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, G26CrMo4 +A or G26CrMo4 +N?

G26CrMo4 +A, by a small margin. Both rate good for machinability — 65/100 against 60/100 for G26CrMo4 +N; for welding the order is G26CrMo4 +A first (good, 60/100) then G26CrMo4 +N (good, 55/100).
