What Are Stainless Steel 310S Butt Weld Fittings?
Stainless Steel 310S Butt weld Fittings are specialized pipe connectors designed for extreme temperature environments. They are joined to piping systems using a butt-welding process, creating a robust, continuous, and leak-proof connection that is as strong as the pipe itself.
The "S" in Grade 310S (UNS S31008) signifies its lower carbon content (0.08% maximum) compared to standard Grade 310. While sharing the excellent high-temperature oxidation resistance of its parent grade, the lower carbon content provides Grade 310S Buttweld Fittings with distinct advantages:
- Improved Weldability: The reduced carbon content minimizes the formation of chromium carbides during welding. This significantly lowers the risk of intergranular corrosion in the heat-affected zone, making these 310S Weldable Pipe Fittings easier to fabricate without requiring post-weld heat treatment in many cases.
- Enhanced Ductility: The low-carbon formulation makes the material more ductile and less susceptible to embrittlement after prolonged exposure to high temperatures. This is crucial for applications involving thermal cycling.
- Superior Resistance to Hot Corrosion: Like standard 310, these High Temperature 310S Fittings offer excellent resistance to sulfidation and other forms of hot corrosion, making them ideal for aggressive furnace atmospheres.
As an expert manufacturer, Amardeep Steel produces a full range of 310S Stainless Steel Piping Components that deliver reliable, long-lasting performance in the most challenging thermal applications.

Heat Treatment & Tolerances of Stainless Steel 310S Butt weld Fittings
Our manufacturing protocol includes essential heat treatment and rigorous dimensional verification to ensure every fitting meets the highest quality standards.
Heat Treatment Requirements
All ASTM A403 WP310S Fittings are provided in a fully solution-annealed condition. This heat treatment involves heating the material to a temperature range of 1040-1150°C (1900-2100°F), followed by a rapid quench. This process ensures the material has a uniform austenitic microstructure, optimal ductility, and maximum corrosion resistance for its intended service environment.
Dimensional Tolerances
We manufacture ASME B16.9 Stainless Steel 310S Fittings to the exact dimensional tolerances outlined in the standard. Our commitment to precision ensures:
- Correct center-to-face and end-to-end dimensions for easy system design and assembly.
- Accurate angularity for perfect pipe alignment.
- Consistent wall thickness for uniform pressure containment.
- Properly formed end bevels to facilitate high-integrity welds.
This focus on accuracy simplifies installation and reduces labor costs for our clients.

Frequently Asked Questions (FAQ's)
1. What is the main benefit of 310S over standard 310 fittings?
The primary benefit is improved weldability and ductility. The lower carbon content in 310S minimizes carbide precipitation during welding, which reduces the risk of intergranular corrosion and embrittlement, making it a more forgiving material for fabrication, especially in heavy sections.
2. What are the service temperature limits for Grade 310S Buttweld Fittings?
Grade 310S Buttweld Fittings provide excellent oxidation resistance for continuous service up to 1040°C (1900°F) and for intermittent service up to 1150°C (2100°F).
3. Is Stainless Steel 310S magnetic?
No. In its annealed state, SS 310S is fully austenitic and non-magnetic. It can become slightly magnetic through severe cold working, but this is not a typical characteristic for fittings.
4. Can 310S be used for applications involving thermal shock?
While 310S has good thermal fatigue resistance, it is not recommended for applications involving severe, repetitive thermal shock, such as liquid quenching. In such cases, other alloys may be more suitable.
5. What information is needed for an accurate price quote?
To get the most accurate price and lead time for your Stainless Steel 310S Butt weld Fittings, please provide the following: the type of fitting (e.g., 90° LR elbow), nominal pipe size, wall thickness (schedule), required quantity, and any specific testing or certification needs.
