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.
