ASTM / JIS / EN Standard 436L Stainless Steel Sheet – Enhanced Formability and Weldability for Manufacturing
In modern precision manufacturing—spanning automotive, appliance, HVAC, and industrial equipment sectors—material performance directly influences production efficiency, part quality, and lifecycle cost. 436L stainless steel sheet, manufactured to ASTM, JIS, and EN international standards, delivers a rare combination of enhanced formability, superior weldability, and robust corrosion resistance, making it a strategic choice for high-volume, high-reliability fabrication processes.
As a low-carbon, titanium-stabilized ferritic stainless steel, 436L overcomes the traditional limitations of ferritic grades (such as poor ductility and weld decay) while avoiding the high cost and supply volatility of nickel-containing austenitic steels like 304 or 316. Its standardized chemistry and mechanical properties ensure seamless integration into global supply chains and automated production lines.
Global Standardization: ASTM, JIS, and EN Compliance
436L is recognized across major international material specifications, ensuring consistency and interoperability:
| Standard System | Designation | Key Requirements |
|---|---|---|
| ASTM (USA) | ASTM A240 / A666 Type 436L | Low C, Ti stabilization, Mo addition, min. elongation ≥22% |
| JIS (Japan) | JIS G 4304 / G 4305 SUS436L | Cr: 16–18%, Mo: 0.75–1.25%, Ti ≥ 4×(C+N) |
| EN (Europe) | EN 10088-2 1.4513 (X6CrMoTi17-1) | Matches JIS/ASTM; widely accepted in EU automotive & appliance sectors |
This multi-standard alignment allows manufacturers to source 436L globally without redesigning components or requalifying processes—critical for multinational OEMs and Tier suppliers.
Why 436L Excels in Manufacturing: Formability & Weldability
✅ Enhanced Formability
Cold-rolled 436L exhibits excellent deep-drawing and stretch-forming capabilities due to:
- Refined grain structure from controlled annealing
- Low yield-to-tensile strength ratio (～0.5)
- High elongation (25–30%) and r-value (plastic strain ratio)
This enables complex geometries—such as exhaust flanges, heat exchanger fins, and appliance housings—to be stamped without edge cracking or surface wrinkling.
✅ Superior Weldability
Unlike unstabilized ferritics (e.g., 430), 436L’s titanium stabilization prevents chromium carbide precipitation at grain boundaries during welding or high-temperature exposure. This eliminates intergranular corrosion in heat-affected zones (HAZ), allowing:
- Reliable TIG, MIG, and resistance spot welding
- No post-weld annealing required in most applications
- Strong, crack-free joints even in thin-gauge sheets (0.5–2.0 mm)
These traits reduce scrap rates, lower rework costs, and support high-speed automated assembly.
Chemical Composition (Typical – Harmonized Across Standards)
| Element | ASTM / JIS / EN Range (%) | Function |
|---|---|---|
| Carbon (C) | ≤ 0.03 | Prevents sensitization |
| Chromium (Cr) | 16.0–18.0 | Corrosion/oxidation resistance |
| Molybdenum (Mo) | 0.75–1.25 | Boosts pitting resistance |
| Titanium (Ti) | ≥ 4×(C + N) | Stabilizes C/N; enhances weld integrity |
| Manganese (Mn) | ≤ 1.0 | Deoxidizer; improves hot workability |
| Silicon (Si) | ≤ 1.0 | Enhances scale resistance |
| Phosphorus (P) | ≤ 0.04 | Minimized to avoid embrittlement |
| Sulfur (S) | ≤ 0.03 | Ensures clean surface and ductility |
| Iron (Fe) | Balance | Base metal |
Note: Minor variations exist between standards, but all maintain core stabilization and corrosion-resistance principles.
Mechanical Properties (Annealed Condition – Cold Rolled Sheet)
| Property | Typical Value | Relevance to Manufacturing |
|---|---|---|
| Tensile Strength | 450–600 MPa | Sufficient strength without brittleness |
| Yield Strength (0.2% offset) | 250–400 MPa | Allows controlled deformation during forming |
| Elongation | 25–30% | Enables deep drawing and bending |
| Hardness (HRB) | ≤ 85 | Compatible with standard tooling |
| n-value (Strain Hardening) | ～0.20 | Good uniform deformation |
| r-value (Plastic Anisotropy) | 1.0–1.4 | Balanced formability in all directions |
These properties support high-speed stamping, roll forming, and hydroforming with minimal springback or tearing.
Common Manufacturing Applications
| Industry | Components Made from 436L Sheet |
|---|---|
| Automotive | Exhaust manifolds, catalytic converter shells, mufflers, EGR tubes |
| Home Appliances | Oven liners, dishwasher tubs, washing machine drums, range hoods |
| HVAC | Heat exchanger plates, condenser housings, ducting |
| Industrial Equipment | Burner parts, furnace trays, chemical handling trays |
| Architectural | Interior panels, trim, decorative elements (in low-corrosion zones) |
Its magnetic nature also benefits sensor-based assembly systems and magnetic handling in robotic production lines.
Available Product Forms & Finishes
| Parameter | Options |
|---|---|
| Thickness | 0.4 mm – 3.0 mm (precision cold rolled) |
| Width | 600 – 1500 mm (standard); up to 2000 mm custom |
| Surface Finish | 2B (most common), BA (Bright Annealed), 2D, Hairline, No.4 |
| Edge Condition | Slit, deburred, or mill edge |
| Delivery Form | Coil, cut-to-length sheets, blanks |
| Tolerances | Thickness: ±0.02 mm; Flatness: <2 mm/m (per EN 10029 / ASTM A480) |
The 2B finish—smooth, semi-reflective, and oxide-free—is ideal for painting, powder coating, or direct use in visible parts.

Quality Assurance for Manufacturing Reliability
Leading mills (e.g., TISCO, Nippon Steel, Acerinox) provide:
- Mill Test Certificates (EN 10204 3.1)
- Chemical & mechanical validation per ASTM/JIS/EN
- Surface inspection reports (ISO 2178/2808)
- Formability testing (cupping, Erichsen, tensile)
- Weld simulation reports (HAZ corrosion testing per ASTM A262)
This documentation ensures traceability and compliance with IATF 16949 (automotive) and ISO 9001 quality systems.
Sustainability & Economic Advantages
- Nickel-free: Avoids price swings and ethical sourcing concerns
- High recycled content: Up to 70% post-consumer scrap
- Long service life: Reduces replacement frequency and waste
- Energy-efficient production: Ferritic steels require less melting energy than austenitics
For manufacturers targeting ESG goals and lean production, 436L offers both environmental and economic benefits.
