Custom CNC Turned Ground 1Cr17Ni2 Stainless Steel Housings
Precision Ground 1Cr17Ni2 Stainless Steel Housings
Hardened, Ground And Dimensionally Stable After Heat Treatment
Material Options & Quality Documentation
We machine and grind 1Cr17Ni2 martensitic stainless steel (AISI 431 class), along with 304, 316L and 17-4PH stainless, hardened and tempered to your specified hardness range. Every shipment includes CMM Dimensional Inspection Reports and Material Mill Certificates to ensure total project transparency. Hardness and heat-treatment records are available on request.
Engineered For Reliability In Aggressive Media
- Ground After Hardening.Bores and outside diameters are ground after quenching and tempering, so roundness, concentricity and surface finish are produced and measured on the finished hardness state.
- Corrosion-Resistant Martensitic Stainless.1Cr17Ni2 pairs high strength and hardness with resistance to water, mild acids and process fluids, suiting pump, valve and chemical service.
- Indexing Notches Matched To Your Drawing.Symmetrical end-face notches are milled to your dimensions and verified on the CMM, keeping anti-rotation location repeatable at assembly.
Tired Of Hardened Parts That Warp Out Of Tolerance After Heat Treatment?
Hardening moves metal, and parts that were accurate before treatment no longer fit afterwards. 7 Swords (Swords Precision) turns and then grinds 1Cr17Ni2 parts after quenching and tempering, so bores stay round, faces stay square and assemblies go together without hand fitting.
