Key Features & Advantages
- Full ASTM A480/A480M Compliance: Every sheet, coil, and plate is produced under rigorous quality control to meet the general requirements for flat-rolled stainless and heat-resisting steel.
- Comprehensive Grade Coverage: From austenitic 304/316/321 series to ferritic 430/441/444/446 and martensitic 410/420 series, we cover the full spectrum of application needs.
- Dual Rolling Process: Cold rolled (0.3mm-6mm) with premium surface finishes and hot rolled (3mm-100mm) for heavy-duty structural and industrial use.
- Versatile Formats: Available as sheets, coils, and plates with custom dimensions to accommodate varying fabrication requirements.
- Premium Surface Options: Standard finishes including 2B, 2D, HL (Hairline), BA (Bright Annealed), No.4, plus decorative colored options in gold, sapphire, rose, black, and bronze — available in both mirror and brushed textures.
- Trusted Mill Sources: Sourced from TISCO, BAOSTEEL, POSCO, JISCO, LISCO, and other leading mills.
Grade Highlight: 444 Ferritic Stainless Steel
The Grade 444 ferritic stainless steel stands out for its exceptional corrosion resistance approaching austenitic levels — at a more competitive cost.
- Superior Chloride SCC Resistance: In chlorine-containing environments, 444 outperforms even 316 stainless steel.
- High Thermal Conductivity: 130%-150% of chromium-nickel austenitic stainless steel.
- Low Thermal Expansion: 60%-70% of chromium-nickel austenitic stainless steel.
- Ideal for Heat Exchangers: Perfect for heat exchangers, water heating systems, and thermal cycling equipment.
