FAQ

Why 316L over 304 for marine?

316L stainless steel includes molybdenum, a key alloying element not present in 304. This addition significantly boosts its resistance to pitting and crevice corrosion, common and severe in chloride-rich marine environments.

The lower carbon content in 316L also reduces the risk of sensitization and intergranular corrosion after welding. This makes it a far more reliable choice for long-term exposure to seawater and harsh offshore conditions.

What tolerances can be achieved?

With advanced CNC machining capabilities and skilled operators, we consistently achieve very tight tolerances for 316L stainless steel parts. Depending on part geometry and size, tolerances typically reach ±0.005mm to ±0.01mm.

These precise tolerances are crucial for the proper fit, function, and sealing of critical marine equipment. Our stringent quality control measures ensure these specifications are met and maintained throughout production.

How is corrosion resistance ensured?

Ensuring corrosion resistance starts with using certified 316L raw material with the correct chemical composition. During CNC machining, we manage process parameters to minimize work hardening and achieve optimal surface finishes.

After machining, comprehensive quality checks, including visual inspection, dimensional verification, and non-destructive testing, confirm part integrity. This holistic approach guarantees maximum resistance to marine corrosion.
