Send Your RFQWhat you get with us
Stable machining of Haynes 230. We plan feeds, toolpaths, fixturing and coolant to control heat and work hardening, so you get consistent features, clean edges and predictable tool life.
Tolerances you can rely on. We hold down to ±0.005 mm on critical dimensions with defined inspection and measurement evidence.
Fewer risks, fewer surprises. We assess material behavior, geometry, tolerances, surface requirements, inspection scope and volume before we cut chips.
Shorter design loops. Same-day/next-day DFM and quoting on complete packages helps you validate designs earlier, reduce build iterations and keep your schedule intact.
Evidence for quality teams. We provide material traceability, FAI, dimensional reports and special-process certificates that pass supplier audits.
A production route you can repeat. Fixtures, tool lists, offsets, inspection plans and records are controlled for continuity over repeat orders.
Why Haynes 230 is challenging—and how we make it predictable
Haynes 230 is a heat-resistant nickel-chromium-tungsten alloy used for hot-gas path parts, furnace fixtures, valves and high-temperature hardware. It work-hardens quickly, runs hot and can burr if not managed.
Heat and work-hardening control
Conservative entry strategies and chip thickness targeting to avoid rubbing and work hardening. High-pressure coolant and toolpath optimization keep heat out of the part and evacuate chips.
Rigid fixturing and tooling
Rigid fixturing and balanced clamping maintain thin walls and flatness. Tool selection focuses on edge strength and wear predictability with documented replacement intervals.
Specialized secondary processes
Use of EDM for sharp internal corners and profiles where milling introduces stress or heat. Finish grinding of sealing faces and bearing fits where surface integrity matters.
Deburring, cleaning and marking are aligned to your drawing and process requirements.

How our speed helps your schedule (without trading off control)
Fast DFM and quoting
When you send a complete drawing/model package, we return targeted manufacturability feedback and a quote same day or next day. You can approve changes or confirm critical features before we fixture—reducing rework.
Parallelized prep
While raw material is confirmed, we program toolpaths, build inspection plans and stage tooling, so cutting starts as soon as material arrives.
Stable cycle times
By controlling heat and tool wear in Haynes 230, we reduce unexpected stoppages—your schedule reflects real throughput, not best-case estimates.
Measurable progress
We share checkpoints (material received, programming complete, first-off verified, inspection complete) so procurement and quality teams can plan downstream steps with confidence.
