Stainless Steel Machining for New Haven, CT

Stainless is a daily material at Wexmar. We machine 303, 304, 316, 410, 17-4 PH, 15-5 PH, and Nitronic 50 for New Haven manufacturers in firearms, medical devices, and industrial manufacturing, manage work hardening with the right feeds and tooling, and ship inspected parts to New Haven on a one-day LTL freight lane from Central New York.

Grades we machine for New Haven

Free-machining 303 for fittings and pins, 304 and 316 for corrosion and sanitary service, 410 and 440C where hardness matters, and 17-4 PH, 15-5 PH, and Nitronic 50 for strength. Heat treat and passivation run through qualified outside processors.

Controlling work hardening

Austenitic grades harden under a rubbing tool. We keep feeds up, use sharp coated carbide, and avoid dwell so bores stay to size and finishes stay clean. Swiss machines handle small-diameter 303 and 316 parts at volume.

Stainless parts New Haven companies buy

Fittings, valve components, manifolds, shafts, pins, bushings, flanges, food and pharma hardware, medical hardware, marine fittings, and fasteners.

Passivation, finish, and documentation

Passivation to ASTM A967 and electropolish are quoted through outside processors. CMM reports and material certs with heat-lot traceability ship with the parts on request.

Stainless Steel Machining for New Haven, CT: FAQ

Which stainless grade is cheapest to machine for New Haven parts?

303 is the free-machining grade and usually the lowest cost to cut. 304 and 316 cost more in cycle time, and PH grades add heat treat.

Do you passivate stainless parts?

Yes, through qualified outside processors, quoted on the same line as the machining and managed by Wexmar.

Can you hold tight bores in 316?

Yes. We control work hardening with feeds and tooling, finish in controlled passes, and verify bores on CMM.
