High-Strength 316/430 Stainless Steel Coil | Polished Precision

Product Overview

Key Technical Specifications

Tensile & Bend Strength

The 316 stainless steel coil delivers superior tensile strength (≥480 MPa) and yield strength (≥175–210 MPa), optimized for high-stress environments like marine equipment and chemical processing plants. Its austenitic structure, enhanced with 2–3% molybdenum, resists pitting corrosion in chloride-rich settings, making it ideal for how to bend stainless steel tubing into a coil applications requiring precision and durability.

The 430 stainless steel coil offers a tensile strength of ≥450 MPa and yield strength of ≥205 MPa, balancing cost and performance for automotive trim, kitchen appliances, and architectural accents. Its ferritic structure ensures magnetic properties, advantageous for components like jenn-air stainless steel coil cartridge jea7000adsa where magnetism aids functionality.

Weight Calculation

Calculate coil weight using:

$$\text{Weight (kg)}=\text{Thickness (mm)}\times \text{Width (m)}\times \text{Length (m)}\times \text{Density (g/cm³)}\times 0.001$$

Example: A 316 coil (2mm thick, 1.5m wide, 50m long) weighs:

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

This formula is critical for logistics planning, especially for kanthal coil vs stainless steel comparisons in industrial projects.

Identification Methods

• Chemical Analysis: Confirm Cr (16–18%), Mo (2–3%) for 316; Cr (16–18%), Mn (≤1.0%) for 430 via XRF testing.
• Spark Testing: 316 produces reddish sparks with minimal branching; 430 generates short, bright sparks due to low nickel.
• Magnetic Testing: 316 remains non-magnetic unless cold-worked; 430 is fully magnetic.

Causes of Stainless Steel Corrosion

1. Chloride Exposure: Coastal or de-icing environments trigger pitting in 430 and intergranular corrosion in 316 if improperly annealed.
2. Galvanic Corrosion: Contact with carbon steel or copper in humidity accelerates oxidation.
3. Mechanical Damage: Scratches from how to bend stainless steel tubing into a coil tools expose raw metal to oxygen.
4. High-Temperature Oxidation: Prolonged exposure above 843°C degrades chromium’s protective oxide layer.
5. Organic Acid Accumulation: Food residues or chemicals form corrosive films on unpolished surfaces.

Applications & Advantages

Versatile Industrial Use

• Marine & Energy: 316 excels in offshore platforms and desalination plants due to saltwater resistance.
• Automotive: 430’s magnetism suits fuel injectors and jenn-air stainless steel coil cartridge jea7000adsa components.
• Architecture: Mirror finishes enhance façades while resisting urban pollution.
