Introducing our high-performance 310 Stainless Steel, engineered to deliver exceptional strength and reliability even under extreme conditions. Ideal for demanding industrial and high-temperature applications, this grade offers a blend of durability, weldability, and long service life — making it a premium choice when ordinary stainless steels won’t perform.

Outstanding High-Temperature & Corrosion Resistance

One of the most remarkable attributes of 310 stainless steel plate is its ability to withstand elevated temperatures with ease. Thanks to its high chromium (24-26%) and nickel (19-22%) content, this alloy resists oxidation in dry air up to roughly 1100 °C to 1150 °C in continuous service.

It also retains excellent toughness at extremely low temperatures and provides superior resistance to scaling, sulfidation, and hot-corrosion compared to many standard austenitic steels.

Superior Mechanical & Fabrication Performance

310s stainless steel sheet is fully austenitic, which ensures good ductility and weldability. It cannot be hardened by conventional heat treatment but responds well to cold working when required.

It exhibits mechanical properties such as minimum tensile strength around 520 MPa and elongation of at least 40% in the annealed condition.

Moreover, its thermal conductivity and diffusivity remain stable at high temperatures, making it ideal for components exposed to high thermal stress.

Wide-Range Applications

When you select 310 Stainless Steel, you’re opting for a material ready to meet the challenges of:

Furnace parts, radiant tubes, muffle, and retort covers for thermal treatment.

Kilns, petroleum refining tube hangers, steam boiler components, and other chemical-processing gear.

Oven linings, conveyor rollers, high-temperature structural supports, cryogenic structures, etc.

Chemical Composition

Typical composition of 310 / 310S grades includes:
Chromium (Cr): ~ 24.0 %–26.0 %

Nickel (Ni): ~ 19.0 %–22.0 %

Carbon (C): max ~ 0.25 % (310) and max ~ 0.08 % (310S, the low-carbon version)

Manganese (Mn): up to ~ 2.00 %

Silicon (Si): up to ~ 1.50 % (for 310)

Phosphorus (P): ≤ 0.045 % and Sulfur (S): ≤ 0.030 %

Iron (Fe): Balance of the alloy.

Mechanical & Thermal Properties

Minimum tensile strength: around ~ 520 MPa for the annealed 310 grade.

Minimum elongation: ~ 40 %

Excellent high temperature strength — ability to resist creep and deformation at elevated service temperatures.

Thermal conductivity and other temperature‐related properties: for example, at 0 °C ~ 12.1 W/mK, rising to ~ 27.7 W/mK at 1000 °C in data for 310 grade.

Physical properties: density ~ 7.89 g/cm³ (0.285 lb/in³) for 310/310S.

High Temperature & Corrosion Resistance

310 Stainless Steel is specifically engineered for high‐temperature environments. It can handle continuous service in oxidizing atmospheres up to ~ 1150 °C and intermittent use even beyond, thanks to its high chromium and nickel contents.
It also exhibits strong resistance to oxidation, sulfidation, and scaling under moderate cyclic high‐temperature exposure.
Moreover, in cryogenic or very low temperature conditions, it maintains toughness and non-magnetic behavior when annealed.

Fabrication & Welding

310 Stainless Steel can be fabricated with standard shop practices: forming, bending, welding, and machining. It is weldable via conventional techniques, though, as with all high‐alloy materials, proper procedures must be followed to preserve corrosion resistance (e.g., avoid contamination, remove heat-tint or slag, clean seams)
It cannot be significantly hardened by heat treatment; instead, it gains strength via cold work when needed.

Applications

Typical applications for 310/310S include:
Furnace and heat‐treatment parts (retorts, muffle tubes, radiant tubes)

Kilns, combustion chambers, high‐temperature piping

Petrochemical components in moderately carburizing or sulfidizing atmospheres

Food processing equipment where high temperature and corrosion resistance are required

Cryogenic structures where toughness at low temperature is beneficial
