Other 17CrNiMo6 tempers and conditions
17CrNiMo6 is also supplied in 9 other conditions. The full side-by-side table is on the 17CrNiMo6 overview.
- AnnealedDefaultPick the usual supply state — soft annealed bar or forgings at ≤229 HB — for rough turning and gear hobbing before carburizing and quenching to the final case hardness.430 MPa yield · 200 HB
- Q&T Blank Hardened <=16mmUse blank hardening and tempering without carburizing to verify core strength or to make small sections up to 16 mm at 960 MPa yield; machinability falls to about 25.960 MPa yield · 40 HRC
- Carburized 58-62 HRCChoose as the final service condition: carburized, hardened and tempered to a 58–62 HRC case over a tough core for heavy gear flank contact and tooth-root bending fatigue.900 MPa yield · 60 HRC
Working with 17CrNiMo6 Carburized 58-62 HRC
Is 17CrNiMo6 easy to machine?
In the annealed condition (≤229 HB) turn, mill and hob normally with coated carbide; after carburizing and quenching only grinding or CBN hard turning is practical.
Can 17CrNiMo6 be welded?
Poor weldability: high carbon equivalent and cold-cracking sensitivity require 250-350 °C preheat, low-hydrogen consumables and prompt post-heat for hydrogen removal; do not weld in carburized areas.
Can 17CrNiMo6 be formed, bent or molded?
Suited to hot forging and hot rolling at 1100-1250 °C, followed by normalizing or annealing; cold formability is limited to cold shearing and light upsetting/extrusion in the +S condition.
What surface finishes work on 17CrNiMo6?
Cannot be anodized. Usual route is gear grinding plus shot peening to raise root fatigue strength, then black oxide, phosphating or rust-preventive oil; non-tooth surfaces can be zinc-nickel plated or painted.
