Smooth Edge 316L/316H/316Ti Stainless Steel Strips and Coils Width 5 - 1500mm

The 316-series austenitic stainless steels are renowned for their corrosion resistance, especially in aggressive environments. While sharing a base composition (chromium, nickel, molybdenum), variants like 316L, 316H, and 316Ti differ in carbon content and alloying elements, leading to distinct mechanical properties, corrosion behaviors, and applications. Below is a detailed technical comparison.

1. 316L Stainless Steel Strip

Key Features:

• Low Carbon Content (≤0.03%): Minimizes carbide precipitation during welding, enhancing corrosion resistance in welded structures17.

• Enhanced Corrosion Resistance: Superior to 304/316 in chloride-rich environments (e.g., marine, chemical processing) and resistant to sulfuric, acetic, and phosphoric acids1410.

• Temperature Limits: Continuous use up to 870°C (intermittent to 925°C). Avoid prolonged exposure at 450–850°C to prevent carbide sensitization17.

Standards & Dimensions:

• Standards: ASTM A240 (U.S.), EN 1.4404 (EU), JIS G4303 (Japan)16.

• Dimensions:

  • Thickness: 0.025–5.0 mm (precision strips down to ±0.01 mm tolerance)148.

  • Width: 3–1,219 mm (custom slitting available)410.

• Surface Finishes: 2B (matt), BA (bright annealed), 6K–9K mirror, brushed, satin168.

• Hardness: Ranges from soft (HV 160) to extra-hard (HV 600), achievable via cold rolling45.

Applications:

• Marine hardware, medical implants, pharmaceutical equipment, and food processing conveyors due to non-reactivity and hygiene410.

• Architectural components in coastal areas (resists salt-induced pitting)17.

2. 316H Stainless Steel Strip

Key Features:

• High Carbon Content (0.04–0.10%): Boosts high-temperature strength via carbide strengthening39.

• Elevated Temperature Performance: Suitable for continuous service up to 815°C (e.g., furnace parts)29.

• Corrosion Resistance: Similar to 316L but prone to sensitization in welds; post-weld annealing is critical3.

Standards & Dimensions:

• Standards: ASTM A240 (316H), ASME SA24069.

• Dimensions: Aligns with 316L (thickness: 0.1–6.0 mm; width: up to 1,500 mm)310.

• Hardness: Typically supplied in annealed condition (HV 150–200); high-temp stability prioritizes over hardness3.

Applications:

• High-temperature systems: Heat exchangers, boiler components, and exhaust manifolds9.

• Chemical processing equipment where creep resistance is essential3.

3. 316Ti Stainless Steel Strip

Key Features:

• Titanium Stabilization (Ti ≥5×C content): Forms Ti carbides, suppressing chromium carbide precipitation and preventing intergranular corrosion in welds369.

• Acid Resistance: Excels against sulfuric, phosphoric, and acetic acids39.

• Mechanical Properties: Higher yield strength (≥205 MPa) vs. 316L, with elongation ≥40%3.

Standards & Dimensions:

• Standards: UNS S31635, EN 1.4571, JIS SUS316Ti36.

• Dimensions: Thickness: 0.03–6.0 mm; Width: 5–1,219 mm (hot-rolled up to 2,000 mm)39.

• Surface/Finish: Mirror (8K), brushed, No.1 industrial finish69.

Applications:

• Chemical tank linings, heat exchangers, and sulfuric acid reactors39.

• Aerospace components requiring combined corrosion resistance and strength6.
