Materials
SUS304 and SUS316 — picking the right grade.
We offer 304 and 316 series stainless steel materials with various coating options to meet the requirements of industrial, architectural, marine, and other demanding applications.
| Grade | Main characteristics | Corrosion resistance | Typical environment | Recommended applications |
|---|---|---|---|---|
| SUS304 | Standard stainless steel grade for general wire rope and cable applications. Good corrosion resistance and strong mechanical performance for indoor, outdoor, and general industrial use. | Good | Indoor, outdoor, general industrial | General wire rope, architectural cable, industrial cable |
| SUS316 | Higher corrosion-resistant stainless steel grade with molybdenum. Recommended for marine, saltwater, chemical, and harsh environments. | High | Marine, saltwater, chemical, harsh | Marine rigging, coastal architecture, chemical industry |
Tip
For coastal architecture and exposed exterior applications, default to SUS316 unless the environment is fully sheltered. The cost difference is small relative to long-term performance.
Tip
For internal control cable, light industrial, and standard architectural runs, SUS304 typically provides the right balance of cost and performance.
