Aesthetic 316L Stainless Steel Coil | Premium Hairline Finish

Product Overview

Key Technical Specifications

Tensile & Bend Strength

The 316L stainless steel coil achieves a tensile strength of ≥480 MPa and yield strength of ≥175 MPa, outperforming standard 304 grades due to its 2–3% molybdenum content. This alloy resists pitting corrosion in chloride-rich environments (e.g., marine or chemical plants) and maintains ductility (≥40% elongation) for complex forming processes like deep drawing. For applications requiring black stainless steel electric stove with coil burners, its thermal stability (up to 870°C) ensures structural integrity under prolonged heat exposure.

Bend strength is enhanced by its austenitic structure, which prevents cracking during fabrication. For architectural projects using bostitch stainless steel coil nails, the material’s hardness (≤200 HV) allows precise fastening without surface deformation.

Weight Calculation

Calculate coil weight using:

$$\text{Weight (kg)}=\text{Thickness (mm)}\times \text{Width (m)}\times \text{Length (m)}\times 7.98\times 0.001$$

Example: A hairline-finished coil (2mm thick, 1.5m wide, 50m long) weighs:

$$2\times 1.5\times 50\times 7.98\times 0.001=11.97\text{kg}$$

Identification Methods

• Chemical Analysis: Verify Cr (16–18%), Ni (10–14%), and Mo (2–3%) via XRF testing.
• Magnetic Testing: Non-magnetic in annealed state; slight magnetism may occur after cold working.
• Spark Testing: Produces short, reddish sparks with minimal branching due to molybdenum content.

Causes of Stainless Steel Corrosion

1. Chloride-Induced Pitting: Saltwater or de-icing salts penetrate passive oxide layers, forming micro-pits.
2. Galvanic Corrosion: Contact with carbon steel or copper in humid environments accelerates oxidation.
3. Mechanical Abrasion: Scratches from bostitch stainless steel coil nails or tools expose raw metal to oxygen.
4. High-Temperature Oxidation: Prolonged exposure above 843°C degrades chromium’s protective oxide film.
5. Organic Acid Accumulation: Food residues or industrial chemicals form corrosive films on surfaces.
