Premium Structural Solutions for Industrial & Architectural Applications

​Product Specifications

​Mechanical Properties

• ​Tensile Strength:

  • ​304: 505 MPa (73,200 psi) | ​316L: 485 MPa (70,300 psi) | ​201: 860 MPa (124,700 psi)
  • Superior resistance to deformation under load, ideal for load-bearing structures like ​stainless steel angle brackets and beams.

• ​Yield Strength:

  • ​304: 215 MPa (31,200 psi) | ​316L: 170 MPa (24,600 psi) | ​201: 310 MPa (45,000 psi)

• ​Elongation at Break:

  • ​304: 70% | ​316L: 60% | ​201: 45%

• ​Bending Strength:

  • Withstands up to 1.5× leg length without cracking (e.g., 140mm leg length supports 210mm bend radius).

​Key Features

1. ​Hot-Rolled Manufacturing Process:

   • Rolled at 1200°C to enhance grain structure uniformity and eliminate internal stress.
   • Acid-pickled surface removes oxide layers for improved corrosion resistance.

2. ​Corrosion Resistance:

   • Chromium (16–20%) and nickel (8–12%) form a self-healing passive oxide layer.
   • ​316L includes 2–3% molybdenum for chloride resistance (ideal for marine ​stainless steel angle steel).

3. ​Weight Calculation:

   • ​Equal-Leg Formula:
     $W=0.00785\times d\times (2b-d)$
     Example: 50×50×5mm → $W=0.00785\times 5\times (100-5)\approx 3.73\text{kg/m}$.
   • ​Unequal-Leg Formula:
     $W=0.00785\times d\times (B+b-d)$
     Example: 63×40×4mm → $W\approx 3.11\text{kg/m}$.

4. ​Marking & Identification:

   • Laser-etched labels include grade (e.g., ​304), thickness, heat number, and TISCO logo.

​Why Stainless Steel Angle Iron May Rust?

While ​stainless steel angle iron is corrosion-resistant, improper handling or environmental factors can cause localized rust:

1. ​Chloride Exposure:
   • Coastal environments or de-icing salts penetrate the passive layer, triggering pitting corrosion.
2. ​Mechanical Damage:
   • Scratches or welding defects expose the base metal to oxidation.
3. ​Galvanic Corrosion:
   • Contact with carbon steel or copper in humid conditions accelerates rusting.
4. ​High-Temperature Oxidation:
   • Prolonged exposure >300°C degrades chromium oxide film.

Prevention Tips:

• Clean surfaces regularly with pH-neutral detergents.
• Apply passivation treatments post-welding.
