ASTM B366 Hastelloy C4 Buttweld Fittings are widely used in industries where extreme corrosion resistance, high temperature stability, and long service life are essential. These fittings are manufactured from Hastelloy C4 (UNS N06455), a nickel-chromium-molybdenum alloy known for its exceptional resistance to aggressive chemicals, including strong acids and oxidizing environments.
We manufacture and supply ASTM B366 WPHC4 UNS N06455 Butt Weld Pipe Fittings that meet international quality standards and are trusted by engineers across chemical processing, petrochemical, and power generation industries. Every fitting is designed for leak-proof performance, high mechanical strength, and long-term reliability.
What Are ASTM B366 Hastelloy C4 Buttweld Fittings?
ASTM B366 Hastelloy C4 Buttweld Fittings are pipe fittings produced according to ASTM B366 / ASME SB366 specifications. These standards cover wrought nickel alloy fittings used for pressure piping and pressure vessel applications.
Hastelloy C4 is specially developed to handle severe corrosion, especially in environments containing:
- Hot hydrochloric acid
- Sulfuric acid
- Chlorinated solvents
- Oxidizing chemicals
Because of its low carbon content, Hastelloy C4 also resists intergranular corrosion even after welding, making it an ideal material for buttweld pipe fittings.

Types of Hastelloy C4 Buttweld Fittings We Offer
We manufacture a complete range of Hastelloy C4 Buttweld Fittings suitable for all industrial piping layouts.
➤ Hastelloy C4 90 Degree Elbow
The Hastelloy C4 90 Degree Elbow is used to change the flow direction by 90°. It ensures smooth flow while maintaining corrosion resistance and pressure integrity.
➤ Hastelloy C4 3D Elbow
A Hastelloy C4 3D Elbow has a longer radius, reducing pressure loss and turbulence. It is commonly used in high-velocity and high-pressure pipelines.
➤ ASME SB366 Hastelloy C4 Buttweld Reducer
The ASME SB366 Hastelloy C4 Buttweld Reducer connects pipes of different diameters. It helps maintain flow efficiency while minimizing stress concentration.
➤ C4 Hastelloy Eccentric Reducer
A C4 Hastelloy Eccentric Reducer is designed for horizontal pipelines where air pockets must be avoided. We are also a trusted C4 Hastelloy Eccentric Reducer Exporter, supplying projects worldwide.
➤ Concentric Reducer
Used mainly in vertical piping systems, concentric reducers ensure smooth and balanced flow transitions.
➤ WNR 2.4610 End Cap
The WNR 2.4610 End Cap is used to close pipe ends securely. It offers excellent pressure handling and corrosion resistance.
➤ Alloy C4 Buttweld End Pipe Cap Fittings
Alloy C4 Buttweld End Pipe Cap Fittings are ideal for sealing pipeline terminations in aggressive chemical environments.
