Working with 32CDV13 Annealed
Is 32CDV13 easy to machine?
Machine in the annealed state (≈230 HB) with coated carbide, rigid setups and generous coolant; at 38 HRC Q&T use low-speed carbide or grinding, and finish-grind after nitriding.
Can 32CDV13 be welded?
One of its selling points — TIG/GTAW with matched or low-alloy filler, preheat 150–250 °C, avoid moisture, then normalize or re-quench-and-temper the assembly (stress relieve at ≥ 30 °C below the final temper).
Can 32CDV13 be formed, bent or molded?
Bend, spin and cold-form only in the annealed condition; hot work 1100→900 °C followed by slow cooling or immediate annealing to avoid quench cracks.
What surface finishes work on 32CDV13?
No anodizing; protect with cadmium or zinc-nickel plating (bake 190 °C/23 h for hydrogen relief), phosphate + primer, or use the nitrided surface with post-oxidation for wear plus mild corrosion resistance.

32CDV13 Annealed — frequently asked
What is 32CDV13 Annealed used for?
32CDV13 Annealed is typically used for aircraft tube structures, landing gear parts and high-strength welded frames. In short: weldable high-strength aerospace steel; nitridable, 450 °C service; high strength-to-weight tubing.
What is the yield strength of 32CDV13 Annealed?
32CDV13 Annealed has a typical yield strength of 550 MPa (79.8 ksi) and a tensile strength of 790 MPa (115 ksi) — stronger than 71% of steel grades. Strength varies by condition: see the 6 listed tempers.
Is 32CDV13 Annealed easy to machine?
Reasonably — machinability is rated good (55/100, better than 62% of steel grades). Machine in the annealed state (≈230 HB) with coated carbide, rigid setups and generous coolant; at 38 HRC Q&T use low-speed carbide or grinding, and finish-grind after nitriding.
Can 32CDV13 Annealed be welded?
Yes — weldability is rated very good (70/100). One of its selling points — TIG/GTAW with matched or low-alloy filler, preheat 150–250 °C, avoid moisture, then normalize or re-quench-and-temper the assembly (stress relieve at ≥ 30 °C below the final temper).
What surface finishes work on 32CDV13 Annealed?
No anodizing; protect with cadmium or zinc-nickel plating (bake 190 °C/23 h for hydrogen relief), phosphate + primer, or use the nitrided surface with post-oxidation for wear plus mild corrosion resistance.
Can 32CDV13 Annealed be formed, bent or molded?
Bend, spin and cold-form only in the annealed condition; hot work 1100→900 °C followed by slow cooling or immediate annealing to avoid quench cracks.
What is the maximum service temperature of 32CDV13 Annealed?
32CDV13 Annealed is rated for continuous use to about 450°C (842 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between 32CDV13 QT-1080-1280 and 32CDV13-N?
QT-1080-1280 is the default condition — standard aerospace structural condition — best balance of 1180 MPa strength, toughness and weld repairability. N: grain-refined intermediate condition for forgings and tube before quench-and-temper. Yield strength is 1,000 MPa in QT-1080-1280 versus 700 MPa in N.
