Strength, Corrosion Resistance,
Hygiene

Stainless steel is the material of choice when parts need to withstand harsh environments, maintain hygiene, or deliver high strength at elevated temperatures. It machines differently than aluminum — requiring lower speeds, more rigid setups, and specialized tooling.

At YEYUAN CNC, we have the rigid machine tools and carbide tooling required for clean, precise stainless steel machining. We understand the feeds, speeds, and coolant strategies that prevent work hardening, tool wear, and dimensional drift.

Precision CNC machined metal components

Stainless Steel Grades
We Machine

Stainless Steel 304

The most widely used stainless steel. Excellent corrosion resistance, good formability, and good machinability. The standard choice for general-purpose stainless parts.

Typical Applications: Food processing equipment, kitchen hardware, architectural panels, chemical containers, medical devices.

Stainless Steel 316L

Molybdenum-enhanced for superior corrosion resistance, especially against chlorides and acids. The low-carbon variant (316L) avoids carbide precipitation during welding.

Typical Applications: Marine hardware, pharmaceutical equipment, surgical implants, chemical processing, offshore oil & gas.

Stainless Steel 303

Free-machining grade with sulfur added for improved chip breaking. The best choice when extensive machining is required and corrosion resistance is secondary.

Typical Applications: Fittings, fasteners, bushings, shafts, and parts with threaded features requiring extensive machining.

Stainless Steel 17-4 PH

Precipitation-hardening martensitic stainless offering high strength (up to 1300 MPa) with good corrosion resistance after heat treatment.

Typical Applications: Aerospace components, pump shafts, valves, high-strength fasteners, nuclear waste processing.

Stainless Steel 420

Martensitic stainless that can be hardened to HRC 50+. Good corrosion resistance in hardened condition. Higher carbon content for wear resistance.

Typical Applications: Cutlery, surgical instruments, valve components, pump parts, molds, wear-resistant tooling.
