Material Specification

Choosing the Right Grade

304 Stainless

Standard grade for indoor machinery, automation, and dry or mildly humid environments. Good resistance to cleaning chemicals. Cost-effective for high-volume orders. Not suitable for continuous salt spray or chloride-heavy process environments.

Food · Automation · Indoor

316 / 316L

Marine and food-grade standard. 2–3% molybdenum addition raises chloride pitting resistance significantly above 304. Required for outdoor, marine, offshore, and food equipment with CIP chemical cleaning. Especially 316 stainless steel has excellent resistance to corrosive saltwater effects.

Marine · Chemical · Pumps

17-4PH

Precipitation-hardened martensitic grade. ≥ 1,310 MPa tensile strength in H900 condition — significantly stronger than 316 at equivalent cross-section. Specified for ball joints in motorsport, aerospace, and high-cycle fatigue applications where load ratings are the primary constraint.
