What Are 310/310S Pipe Fittings?
310/310S Pipe Fittings are specialized components designed to connect, control, and direct piping systems operating under intense heat and corrosive conditions. What makes them so special is their high-chromium (around 25%) and high-nickel (around 20%) austenitic stainless steel composition. This powerful alloy gives them exceptional resistance to oxidation and corrosion at continuous service temperatures up to 1150°C (2100°F).
While often grouped together, the 310 family has distinct grades for specific applications:
- Stainless Steel 310 Pipe Fittings (SS 310 Pipe Fittings): This is the standard grade, offering a fantastic combination of high-temperature strength and corrosion resistance.
- Stainless Steel 310S Pipe Fittings (SS 310S Pipe Fittings): The 'S' denotes a lower carbon content. This is crucial for applications involving welding. The reduced carbon in 310S stainless steel fittings minimizes carbide precipitation, which prevents intergranular corrosion at the weld seams and improves overall weldability. This makes it the preferred choice for fabricated high temperature 310S fittings.
- Stainless Steel 310H Pipe Fittings: This grade has a higher carbon content, which provides superior creep strength, making it ideal for structural applications at very high temperatures.
All these grades fall under the ASTM A403 WP310S fittings specification, which guarantees they are manufactured to the chemical and mechanical standards required for high-stress, high-temperature pressure piping.

Heat Treatment & Tolerances of 310/310S Pipe Fittings
Quality isn't just about the material; it's about how it's processed. Proper heat treatment and tight dimensional control are fundamental to creating a reliable fitting.
Heat Treatment Requirements of 310/310S Pipe Fittings
All our 310/310S Pipe Fittings are supplied in a solution-annealed condition. This heat treatment involves heating the fittings to a specific temperature range (typically 1040-1150°C) and then rapidly cooling them. This process accomplishes several critical goals:
- It relieves any internal stresses created during the manufacturing process.
- It dissolves chromium carbides, maximizing the material's corrosion resistance.
- It creates a stable and uniform austenitic microstructure, ensuring consistent performance.
Dimensional Tolerances of 310/310S Pipe Fittings
A fitting is only as good as its fit. We manufacture our products to the strict dimensional tolerances outlined in ASME B16.9 (for buttweld fittings) and ASME B16.11 (for forged fittings). This guarantees that every angle, every diameter, and every end-finish is precise, allowing for seamless installation and leak-proof, reliable joints.

Frequently Asked Questions (FAQ's)
1. What is the main advantage of using 310S over 310?
The primary advantage of 310S is its lower carbon content, which significantly improves its weldability. It reduces the risk of sensitization (intergranular corrosion) at the weld joints, making it the superior choice for fabricated equipment that will operate in corrosive, high-temperature environments.
2. What is the maximum temperature these fittings can withstand?
Grade 310/310S stainless steel offers excellent oxidation resistance in continuous service up to 1150°C (2100°F) and in intermittent service up to 1040°C (1900°F), provided that reducing sulfur gases are not present.
3. Is 310S magnetic?
No. Like other austenitic stainless steels, 310S is non-magnetic in the annealed condition. It may become slightly magnetic after extensive cold working, but this is uncommon for pipe fittings.
4. Can I get a material test certificate with my order?
Absolutely. We supply a Mill Test Certificate (MTC) in accordance with EN 10204 3.1 with every order. This certificate provides full traceability and documents the chemical and mechanical properties of the material, ensuring it meets all required specifications
