Stainless Steel CNC Machining for 304, 316L and Precision Components
Stainless steel is the material of choice for demanding environments: corrosive media, high temperatures, food contact and high-pressure fluid systems. SCreate has deep expertise in machining 304, 316L, 440C, 17-4PH and other stainless grades. From engine intake valves and high-pressure hydrogen fittings to pharmaceutical equipment and precision camshafts, our CNC turning, milling and grinding capabilities deliver the dimensional accuracy and surface quality that stainless steel applications demand.
Capabilities
What We Deliver
304 Stainless Steel
The most widely used grade — excellent corrosion resistance, good machinability. Used for camshafts, support columns, flanges and structural components.
316L Stainless Steel
Superior corrosion resistance in chloride and acidic environments. Preferred for hydrogen fittings, medical components and chemical processing parts.
440C & 17-4PH Stainless
Martensitic and precipitation-hardened grades for high hardness and strength — indexing discs, precision bearings and cutting tools.
High-Pressure Components
Flanges, fittings and valve bodies tested to 10MPa+ gas/liquid pressure. Sealing surface finish Ra ≤0.8 for leak-free performance.
Passivation & Surface Treatment
Electropolishing, passivation (ASTM A967), vibratory finishing and mirror polishing (Ra 0.1–0.4).
Thread & Sealing Expertise
Metric, G (BSP), NPT and JIC threads machined to gauge tolerance with full thread gauging inspection.

FAQ
Frequently Asked Questions
Why is stainless steel more difficult to machine than aluminum?
Stainless steel has lower thermal conductivity and work-hardens during machining. This increases cutting forces and accelerates tool wear. We use optimised cutting parameters, sharp carbide tooling and flood coolant to maintain accuracy.
What surface finish can you achieve on stainless steel parts?
Standard CNC turning achieves Ra 0.8–1.6. With fine finishing passes we achieve Ra 0.4. Electropolishing can reach Ra 0.1–0.2 for medical or optical applications.
Can you machine high-pressure stainless steel fittings and valves?
Yes. We manufacture 316L high-pressure fittings for hydrogen storage systems rated to 10MPa and above. Parts are pressure-tested and dimensional reports are provided.
