Cold Rolled 436L Stainless Steel Sheet (0.5–3.0mm Thickness) – Engineered for High-Temperature Environments
In industries where performance under thermal stress is non-negotiable—such as automotive exhaust systems, industrial heat exchangers, and energy-efficient appliances—material selection directly impacts safety, longevity, and operational efficiency. Cold rolled 436L stainless steel sheet, with a precision thickness range of 0.5 mm to 3.0 mm, offers an optimal balance of high-temperature stability, corrosion resistance, formability, and cost-effectiveness. This advanced ferritic stainless steel is specifically engineered for components exposed to prolonged elevated temperatures and aggressive environmental conditions.
Manufactured to meet global standards including ASTM A240, JIS G 4305 (SUS436L), and GB/T 4239, cold rolled 436L delivers superior surface finish, tight dimensional tolerances, and consistent mechanical properties—making it ideal for high-precision industrial and automotive applications.
Why Cold Rolled 436L Excels in High-Temperature Service
436L is a low-carbon, titanium-stabilized ferritic stainless steel enhanced with molybdenum (Mo) to boost resistance against oxidation and localized corrosion. The “L” denotes ultra-low carbon content (≤0.03%), which—combined with titanium stabilization—prevents chromium carbide precipitation during welding or exposure to temperatures between 425°C and 815°C, a range where many stainless steels suffer from sensitization and intergranular corrosion.
The cold rolling process further refines the grain structure, resulting in:
- Improved surface smoothness and reflectivity
- Higher strength and hardness compared to hot-rolled counterparts
- Enhanced flatness and uniform thickness (critical for stamping and deep-drawing)
- Better control over final mechanical properties
These attributes make cold rolled 436L particularly suited for thin-gauge components that must endure repeated thermal cycling without warping, cracking, or degrading.
Key Performance Advantages
| Feature | Benefit in High-Temperature Applications |
|---|---|
| Continuous Use up to 700°C (1292°F) | Maintains structural integrity in exhaust manifolds, catalytic converters, and boiler housings |
| Molybdenum (0.75–1.25%) | Resists pitting from road salts, acidic condensates, and sulfur compounds |
| Titanium Stabilization | Eliminates weld decay; ensures corrosion resistance in heat-affected zones |
| Low Thermal Expansion | Reduces thermal stress and distortion during heating/cooling cycles |
| High Thermal Conductivity (～26 W/m·K) | Promotes efficient heat dissipation in heat exchangers and mufflers |
| Nickel-Free Composition | Cost-stable alternative to austenitic grades like 304/316 |
Typical Industrial Applications
- Automotive: Exhaust pipes, resonators, EGR tubes, catalytic converter shells
- HVAC & Appliances: Oven liners, dishwasher interiors, dryer drums
- Energy: Flue gas ducts, solar thermal collectors, biomass boiler components
- Industrial Equipment: Heat shields, furnace parts, chemical processing trays
Its combination of thin-gauge manufacturability and high-temperature resilience allows engineers to design lighter, more compact, and fuel-efficient systems without compromising durability.
Chemical Composition (Weight % – Typical for Cold Rolled 436L)
| Element | Content (%) | Role |
|---|---|---|
| Carbon (C) | ≤ 0.03 | Prevents sensitization during welding |
| Chromium (Cr) | 16.0–18.0 | Forms protective Cr₂O₃ oxide layer |
| Molybdenum (Mo) | 0.75–1.25 | Enhances pitting/crevice corrosion resistance |
| Titanium (Ti) | ≥ 4×(C + N) | Stabilizes carbon/nitrogen; improves weld integrity |
| Manganese (Mn) | ≤ 1.0 | Aids hot workability |
| Silicon (Si) | ≤ 1.0 | Improves scale resistance at high temps |
| Phosphorus (P) | ≤ 0.04 | Controlled to avoid embrittlement |
| Sulfur (S) | ≤ 0.03 | Ensures good surface quality and ductility |
| Iron (Fe) | Balance | Base metal |
Note: Exact composition may vary slightly per specification (e.g., JIS vs. ASTM).
