Product Description
| Grade | Key Composition | Corrosion Resistance | Typical Applications | Suitable Environment |
|---|---|---|---|---|
| 304 (06Cr19Ni10, S30400) | Cr 18-20%, Ni 8-10.5%, C≤0.08% | Excellent (atmosphere, fresh water, weak acid & alkali) | Construction, food equipment, chemical pipelines, general machinery | Inland, neutral environment |
| 316L (022Cr17Ni12Mo2, S31603) | Mo 2-3%, C≤0.03% | Outstanding (pitting resistance, crevice corrosion, seawater) | Marine engineering, coastal curtain walls, pharmacy, desalination | Coastal, chemical, high-corrosion |
| 321 (06Cr18Ni11Ti) | Stabilized with Ti | High temperature resistance, anti-sensitization | Boilers, heat exchangers, high-temperature pipelines | High-temperature & welded conditions |
| 430 (1Cr17) | Ferritic, nickel-free | Good, low cost | Decoration, home appliances, kitchenware | Low corrosion, cost-sensitive projects |
- Raw material: stainless steel billet (continuous casting / forged billet)
- Hot rolling: heating → rough rolling → finish rolling → cooling → cutting → pickling & passivation
- Cold rolling / cold drawing: hot rolled flat bar → pickling → cold rolling / cold drawing → straightening → solution/annealing → fine cutting
- Inspection: spectral composition analysis, dimensional inspection, surface quality, mechanical properties (tensile, hardness), third-party inspection, MTC, NDT (if required)
- Construction: curtain wall frames, steel structure supports, railings and handrails
- Machinery: equipment bases, guide rails, flanges, connectors
- Chemical & food: pipeline supports, reactor supports, clean room components
- Ship & marine: hull structures, seawater pipeline fixtures, offshore platforms
- Power: power station boilers, condensers, electrical equipment frames
- General environment: choose 304
- Coastal / chemical / high-corrosion: choose 316L
- Welded structures: choose 316L / 321
- Cost-sensitive & low corrosion: choose 430
- Precision machinery: use cold drawn flat bar (tight tolerance, high surface quality)
