Stainless Steel Pipe Fittings

Stainless fittings are specified when plating on carbon is not enough — outdoor exposure, chlorides, washdown chemistry, or customer standards that freeze 304 / 316 families. Hongqian machines and forms stainless steel pipe fittings as OEM components: adapters, connectors, plugs, and custom turned geometries tied to your print.

Expect higher material and cycle cost than carbon on the same silhouette. In return you reduce coating dependence and improve corrosion life when the grade matches the media. We commonly work with 304 / 304L and 316 / 316L, with 303 considered when machining complexity is high and corrosion demand is moderate.

Design details that matter in stainless

• Thread standard and galling risk on make/break assemblies
• Passivation after machining
• Whether a carbon + plating alternative is acceptable for cost-down SKUs
• Document needs: MTR, dimensional report, gauge records

Quoting stainless without surprise cost

Stainless quotes move faster when the print already names the grade, thread standard, and passivation expectation. If a carbon alternative is acceptable for some SKUs, say so — we can price both paths. Tool wear, blank strategy, and secondary operations differ from carbon, so we re-validate the process when a program switches metals mid-life.

Export packing includes protection against contamination and transit damage. Request photo packing or labeled kits when your warehouse needs kit-level traceability.
