Stainless Steel Long Products

Description

1. Product Overview
This product range comprises high-integrity stainless steel long products—including round bars, hexagonal bars, angles, channels, and wire rods—engineered for structural and mechanical applications across corrosive and high-temperature environments. Primary industrial use spans oil & gas, chemical processing, automotive, and heavy construction. The key value proposition is a superior strength-to-corrosion resistance ratio, delivering extended service life and reduced lifecycle maintenance costs. Strategically, these products are critical for industries requiring asset reliability in aggressive conditions, making them a cornerstone of global supply chains for capital-intensive infrastructure.

2. Key Specifications & Technical Characteristics

• Chemical Composition (typical grade 304/316L):

  • Cr: 18.0–20.0% (304) / 16.0–18.5% (316L)

  • Ni: 8.0–10.5% (304) / 10.0–14.0% (316L)

  • Mo: – (304) / 2.0–3.0% (316L)

  • C: ≤0.03% (L-grade)

  • Fe: Balance

• Purity Level: Vacuum degassed, inclusion rating ≤1.5 per ASTM E45

• Physical Characteristics:

  • Form: Bright drawn, peeled, ground, or hot-rolled

  • Diameter: 5 mm – 300 mm (bars); wire rods: 5.5 – 25 mm

  • Surface finish: 1D, 2B, or peeled

  • Density: 7.93 g/cm³ (nominal)

• Packaging Options:

  • Hexagonal bundles (500–2000 kg) + moisture-barrier VCI paper

  • Steel coil carriers for wire rods

  • Custom color-coded end caps for grade traceability

• Shelf Life: Indefinite under dry, covered storage (no degradation); corrosion warranty 24 months from ship date if stored as specified

3. Core Industrial Applications

• Primary industries: Oil & gas downhole equipment, desalination plants, food processing, automotive fasteners, marine architecture

• Specific use cases:

  • Pump shafts and valve stems (316L): Outlasts carbon steel by 5–8x in saline environments

  • Structural angles in chemical plants (304L): Resists pitting from chlorides, eliminating need for coating replacement

  • High-strength fasteners (duplex grades): Provides 2x yield strength vs. 304, enabling lighter assemblies

• Why better: Homogenous microstructure via continuous casting + hot rolling eliminates center porosity, ensuring consistent machinability and fatigue resistance. Cost advantage: 15–20% longer tool life during CNC machining compared to conventionally cast long products.

4. Competitive Advantages
