Cold Rolled and Hot Rolled 416 Stainless Steel Plate & Sheet – Magnetic, Heat-Treatable Alloy for Precision Parts
Product Overview
416 stainless steel is a martensitic, free-machining stainless alloy renowned for its exceptional machinability, magnetic properties, and ability to be heat-treated for enhanced strength. Available in both cold-rolled and hot-rolled forms, this versatile material serves as the backbone for high-precision components across automotive, aerospace, fluid control, instrumentation, and industrial machinery sectors.
The key differentiator of 416 stainless steel lies in its controlled sulfur content (≥0.15%), which significantly improves chip-breaking behavior during machining—making it the most machinable stainless steel in the martensitic family. Whether you require the tight tolerances and smooth finish of cold-rolled sheet or the cost-effective robustness of hot-rolled plate, 416 delivers consistent performance for demanding mechanical applications.
Crucially, 416 is magnetic and heat-treatable, enabling hardening to 25–45 HRC—ideal for wear-resistant shafts, gears, valve stems, and fasteners where dimensional stability and surface integrity are critical.
⚠️ Note: Due to sulfur-induced weldability limitations and moderate corrosion resistance, 416 is not recommended for welded structures or aggressive environments (e.g., marine, acidic, or high-chloride). For such cases, consider 316L or 17-4PH.
Cold-Rolled vs. Hot-Rolled: Key Differences
| Feature | Cold-Rolled 416 | Hot-Rolled 416 |
|---|---|---|
| Surface Finish | Smooth, uniform (Ra 0.4–1.0 µm); often 2B/BA | Scaled, rougher; may require pickling |
| Dimensional Tolerance | Tight (±0.05 mm typical) | Looser (±1% thickness or more) |
| Flatness | Excellent | Moderate (may have slight bow/warp) |
| Mechanical Strength | Higher (due to strain hardening) | Lower (annealed structure) |
| Typical Thickness Range | 0.5 mm – 6.0 mm | 3.0 mm – 50.0+ mm |
| Best For | Precision parts, CNC machining, thin components | Structural blanks, forgings, heavy-duty parts |
Both forms are fully heat-treatable and share identical chemical composition per ASTM A276/A240.
Chemical Composition (AISI 416 / UNS S41600)
| Element | Content (%) |
|---|---|
| Carbon (C) | ≤ 0.15 |
| Manganese (Mn) | ≤ 1.00 |
| Phosphorus (P) | ≤ 0.040 |
| Sulfur (S) | ≥ 0.15 |
| Silicon (Si) | ≤ 1.00 |
| Chromium (Cr) | 12.0 – 14.0 |
| Nickel (Ni) | ≤ 0.60 |
| Iron (Fe) | Balance |
The elevated sulfur content enables superior machinability but reduces ductility and weldability.
Mechanical Properties Comparison
| Condition | Tensile Strength | Yield Strength | Elongation | Hardness (HB) |
|---|---|---|---|---|
| Cold-Rolled (Annealed) | 585–760 MPa | 310–450 MPa | 18–22% | 190–220 |
| Hot-Rolled (Annealed) | 515–725 MPa | 275–415 MPa | 20–25% | ≤183 |
| Heat-Treated (H&T) | Up to 1,000 MPa | Up to 850 MPa | 10–15% | 25–45 HRC |
Heat treatment: Austenitize at 980–1,010°C → oil quench → temper at 150–650°C.
Physical & Thermal Properties
| Property | Value |
|---|---|
| Density | 7.74 g/cm³ |
| Melting Range | 1,450–1,510°C (2,642–2,750°F) |
| Thermal Conductivity @ 100°C | 24.9 W/m·K |
| Specific Heat | 460 J/kg·K |
| Coefficient of Thermal Expansion | 10.0 µm/m·°C (20–100°C) |
| Magnetic? | Yes – ferromagnetic |
Its magnetic nature supports use in sensors, solenoids, and electromagnetic actuators—unlike non-magnetic 300-series grades.
Machinability Advantage
416 stainless steel offers ～85% machinability relative to B1112 carbon steel, far surpassing common austenitic grades:
| Grade | Relative Machinability | Tool Wear vs. 304 |
|---|---|---|
| 416 | 85% | 40–50% less |
| 303 | 78% | 30% less |
| 304 | 45% | Baseline |
| 316 | 40% | Higher |
Benefits include:
- Faster cutting speeds
- Reduced power consumption
- Superior surface finish on turned/milled parts
- Extended insert life in high-volume production
Typical Applications by Form
✅ Cold-Rolled 416 Sheet (0.5–6.0 mm)
- Valve stems and spindles
- Instrumentation housings
- Automotive sensor brackets
- Precision gears and bushings
- Electrical contact carriers
✅ Hot-Rolled 416 Plate (3–50+ mm)
- Pump shaft blanks
- Forging stock for fasteners
- Jig and fixture bases
- Industrial knife blades
- Custom machined flanges
Corrosion Resistance Profile
Resists:
- Atmospheric oxidation (urban/industrial)
- Freshwater exposure
- Mild organic acids (short-term)
- Steam and dry gases
Avoid in:
- Saltwater or coastal environments
- Hydrochloric/sulfuric acid service
- Chloride-rich process fluids
- Welded assemblies
Passivation or electropolishing can enhance surface oxide layer and improve mild corrosion performance.
