Industrial-Grade 316H Stainless Steel Plate – Superior Creep Resistance & Durability for Demanding High-Temperature Environments

Product Overview

Industrial-grade 316H stainless steel plate is a premium austenitic alloy engineered specifically for long-term structural integrity in high-temperature, high-stress industrial applications. Designated by the “H” suffix (per ASTM A240/ASME SA-240), this grade features a controlled carbon content of 0.04–0.10%, which dramatically enhances creep strength, stress-rupture resistance, and microstructural stability at operating temperatures between 550°C and 750°C (1022°F–1382°F).

Widely specified in power generation, petrochemical refining, nuclear energy, and industrial furnace systems, 316H delivers unmatched durability where standard 316 or 316L would rapidly degrade under thermal creep or corrosive attack.

Manufactured to stringent industrial standards and supplied in hot-rolled, solution-annealed condition, this plate ensures consistent performance, weldability, and compliance with global pressure equipment codes.

Why 316H? The Industrial Advantage

Superior creep resistance—critical for components under constant load at high temps
Excellent corrosion protection—thanks to 2–3% molybdenum and 16–18% chromium
Code-approved material—fully compliant with ASME BPVC, ASTM A240, and PED
Enhanced mechanical strength at elevated temperatures vs. low-carbon grades
Proven in extreme service—from nuclear reactors to sulfur recovery units

Unlike general-purpose stainless steels, industrial-grade 316H is purpose-built for mission-critical infrastructure where failure is not an option.

Chemical Composition (UNS S31609 / ASTM A240)

Element	Weight % (Typical Range)
Carbon (C)	0.04 – 0.10
Chromium (Cr)	16.0 – 18.0
Nickel (Ni)	10.0 – 14.0
Molybdenum (Mo)	2.0 – 3.0
Manganese (Mn)	≤ 2.00
Silicon (Si)	≤ 0.75
Phosphorus (P)	≤ 0.045
Sulfur (S)	≤ 0.030
Iron (Fe)	Balance

Mechanical Properties (Solution Annealed Condition)

Property	Minimum Requirement
Tensile Strength	515 MPa (75,000 psi)
Yield Strength (0.2% offset)	205 MPa (30,000 psi)
Elongation	≥ 40% (in 50 mm)
Hardness	≤ 95 HRB
Density	8.0 g/cm³
Modulus of Elasticity (RT)	～193 GPa

All plates are supplied with EN 10204 3.1 Mill Test Reports, including certified chemistry and mechanical test data.

Creep & Rupture Performance – The Core Strength

The defining feature of 316H is its exceptional resistance to time-dependent deformation (creep) under load at high temperatures—a critical factor in pressure vessels, headers, and piping systems.

Approximate 10,000-Hour Rupture Strength

Temperature	Stress to Cause Rupture
600°C	～80 MPa
650°C	～55 MPa
700°C	～35 MPa
750°C	～20 MPa

Source: ASME Boiler & Pressure Vessel Code, Section II, Part D

This performance enables safe, long-life operation in:

Superheater outlet headers
Steam generator tubesheets
Reactor vessel internals
High-pressure reformer tubes

Corrosion Resistance in Harsh Industrial Media

316H’s alloying elements provide robust defense against:

Chloride-induced pitting (e.g., coastal plants, desalination)
Sulfidic corrosion in sour crude oil and gas processing
Organic acids (acetic, formic) in chemical synthesis
Oxidizing flue gases in waste incineration and power boilers

While not a super-austenitic grade, 316H significantly outperforms 304H and carbon steel in aggressive environments—offering a cost-effective balance of performance and longevity.

Key Industrial Applications

Sector	Typical Components
Thermal Power	Main steam piping supports, boiler drum baffles, reheater headers
Nuclear Energy	Intermediate heat exchangers, sodium circuit components (fast reactors)
Oil & Gas Refining	Hydrocracker reactors, coker drums, sulfur recovery unit (SRU) ducting
Chemical Processing	High-temp reactor shells, acid condenser plates, distillation column trays
Industrial Furnaces	Radiant tubes, retort fixtures, burner nozzles

Fabrication & Welding Best Practices

Forming: Excellent ductility allows cold bending; anneal after severe deformation.
Machining: Moderate difficulty—use sharp tools, low speeds, and ample coolant to counter work hardening.
Welding:
- Use matching filler (e.g., ER316H) or low-carbon (ER316L) for thin sections.
- Maintain interpass temperature <150°C (300°F).
- Avoid prolonged exposure in 425–860°C (800–1600°F) to prevent sensitization.
Heat Treatment: Solution anneal at 1040–1150°C (1900–2100°F), followed by rapid quenching

316H vs. Common Industrial Alternatives

Grade	Carbon (%)	Creep Strength	Corrosion Resistance	Best Use Case
316H	0.04–0.10	★★★★☆	★★★★☆	High-temp + moderate corrosion
316L	≤0.03	★★☆☆☆	★★★★☆	Welded corrosion service (<400°C)
304H	0.04–0.10	★★★☆☆	★★☆☆☆	Non-chloride high-temp service
321H	～0.08	★★★★☆	★★★☆☆	Stabilized welding service
347H	～0.08	★★★★☆	★★★★☆	High-temp stabilized (niobium)

316H remains the optimal choice when both elevated-temperature strength and chloride resistance are required.
