Residential & Commercial Indoor Scenario
Applicable Projects:Coastal walkways, pool decks, port buildings, coastal villas, offshore platforms
Coastal & Marine Environment Scenario
Applicable Projects:Airport corridors, cross-sea bridges, shopping mall escalators, stadiums, high-speed rail stations
Large-Scale Public Engineering Scenario
Core Specifications Comparison
| Application Scenario | Product Model | Material | Key Dimensions | Corrosion Resistance | Load-Bearing Capacity | Price Range |
| Residential & Commercial Indoor | Standard Type | 201/304 Stainless Steel | OD 50-89mm (Round)/40-50mm (Square), Thickness 1.2-2.5mm | Salt spray ≥2000h (NSS) | Meet general residential needs | USD 8-25 / Piece |
| Coastal & Marine Environment | Marine Grade | 316/316L Stainless Steel | OD 63-102mm (Round)/50-60mm (Square), Thickness 2.0-3.0mm | Salt spray ≥5000h (NSS), anti-chloride | Meet commercial project needs | USD 12-32 / Piece |
| Large-Scale Public Engineering | Heavy Duty | 304/316 Stainless Steel | OD 102-114mm (Round)/60-80mm (Square), Thickness 3.0-4.0mm | Salt spray ≥3000h (NSS) | ≥1.5kN/m, high-traffic safe | USD 18-45 / Piece |
304 vs 316: Key Differences & Selection Guide
| Comparison Item | 304 Stainless Steel | 316/316L Stainless Steel | Practical Suggestion |
| Chemical Composition | Cr 18-20%, Ni 8-10.5%, C ≤0.08% | Cr 16-18%, Ni 10-14%, Mo 2-3%, C ≤0.03% (316L) | Molybdenum is the core of corrosion resistance |
| Corrosion Resistance | Suitable for dry/indoor environments | Excellent for chloride environment (3-5x better than 304) | Choose 316 for areas within 5km of coastline |
| Cost | Cost-effective (40-50% lower than 316) | Higher cost (premium for molybdenum) | Balance cost and service life |
| Selection Suggestion | Indoor/dry outdoor, residential projects, budget-sensitive | Coastal/marine, pool, chemical area, long service life demand | Refer to project environment & service life |

FAQ
Request a spectral analysis report from the supplier—316 must contain ≥2% molybdenum. We provide free testing reports for all orders, and can also send a molybdenum testing solution for on-site verification.
