Stainless Steel Nitronic 50 Cold Drawn vs Nitronic 50 Hot Rolled

Stainless Steel · Nitronic 50 temper comparison

Nitronic 50 Cold Drawn and Nitronic 50 Hot Rolled are two conditions of the same stainless steel grade, Nitronic 50: Cold Drawn versus Hot Rolled. The chemistry is identical, so every difference below comes from the condition. Nitronic 50 Cold Drawn is the stronger of the two: yield strength 760 MPa (110 ksi) against 500 MPa (72.5 ksi) for Nitronic 50 Hot Rolled, about 52% more; tensile strength follows at 965 MPa (140 ksi) vs 830 MPa (120 ksi). In exchange, Nitronic 50 Hot Rolled is the more ductile: elongation 38% versus 25% for Nitronic 50 Cold Drawn, and Nitronic 50 Cold Drawn is harder (300 HB vs 240 HB).

Nitronic 50 Cold Drawn vs Nitronic 50 Hot Rolled — frequently asked

Is Nitronic 50 Cold Drawn stronger than Nitronic 50 Hot Rolled?

Yes. Nitronic 50 Cold Drawn has a typical yield strength of 760 MPa (110 ksi) against 500 MPa (72.5 ksi) for Nitronic 50 Hot Rolled — about 52% more. Tensile strength is 965 MPa (140 ksi) vs 830 MPa (120 ksi).

Which condition does FabDigit quote by default, Cold Drawn or Hot Rolled?

Solution Annealed is the default Nitronic 50 condition in the FabDigit quote flow (neither Cold Drawn nor Hot Rolled). 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, Nitronic 50 Cold Drawn or Nitronic 50 Hot Rolled?

Nitronic 50 Cold Drawn, by a small margin. Both rate poor for machinability — 32/100 against 25/100 for Nitronic 50 Hot Rolled; for welding the order is Nitronic 50 Hot Rolled first (good, 68/100) then Nitronic 50 Cold Drawn (good, 60/100).
