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.
