ASTM B366 Hastelloy G30 Buttweld Fittings are engineered for demanding industrial environments where corrosion resistance, strength, and long-term reliability are critical. Manufactured from Hastelloy® G30 – a high-performance nickel alloy, these fittings perform exceptionally well in highly corrosive chemical processes, especially those involving phosphoric acid, sulfuric acid, and mixed acid environments.
We manufacture and supply a full range of ASTM B366 WPHG30 UNS N06030 Butt Weld Pipe Fittings that meet international quality standards and are trusted across chemical processing, fertilizer plants, petrochemical units, and power generation industries.
Our focus is always on quality, application-specific performance, and customer trust, not just selling a product.
What is Hastelloy® G30 – Nickel Alloy?
Hastelloy® G30 (UNS N06030 / WNR 2.4603) is a nickel-chromium-iron-molybdenum alloy with copper and tungsten additions. It was specifically developed to resist severe chemical corrosion, especially in environments where stainless steels and many other nickel alloys fail.
Key Characteristics of Alloy G30- Outstanding resistance to phosphoric acid
- Excellent protection against pitting and crevice corrosion
- Strong resistance to stress corrosion cracking
- Good mechanical strength at both ambient and elevated temperatures
- Suitable for fabrication and welding using standard methods
Because of these properties, ASTM B366 Hastelloy G30 Pipe Fittings are widely used where long service life and safety are non-negotiable.
