ASTM B564 Monel K500 Forged Fittings are premium nickel-copper alloy components designed for high- pressure and highly corrosive environments. At Solitaire Fittings, we manufacture and supply precision- engineered Monel K500 Forged Fittings that comply with international standards and are widely used in oil & gas, offshore, marine, power generation, and chemical industries.
Manufactured from Monel Alloy 400 (UNS N04400), these forged fittings are produced according to ASTM B564 (also known as ASME SB564), ensuring strict compliance with international quality and performance standards
As a reliable Monel 400 Forged Fittings Manufacturer and Supplier, we provide precision-engineered solutions for critical industrial piping systems across India and global markets.
Understanding ASTM B564 Monel K500 (UNS N05500)
ASTM B564 covers nickel alloy forgings including Monel K500 (UNS N05500). The equivalent ASME specification is ASME SB564. Monel K500 is a precipitation-hardened nickel-copper alloy with added aluminum and titanium. Compared to Monel 400, it provides:
- Significantly higher tensile and yield strength
- Excellent resistance to seawater and marine corrosion
- Superior resistance to stress corrosion cracking
- Excellent fatigue and wear resistance
- Non-magnetic behavior even at low temperatures
Because of these properties, Monel K500 is frequently selected for offshore and subsea applications where failure is not an option.
Understanding ASTM B366 and ASME SB366 Standards
The ASTM B366 specification is issued by ASTM International and covers factory-made wrought nickel alloy fittings, including Monel 400. The equivalent ASME SB366 standard is published by ASME. These standards make sure that:
- The chemical composition of the alloy is correct
- The mechanical properties meet required strength levels
- The fittings are manufactured and tested properly
- The products are suitable for pressure and critical service piping
So, when you choose ASTM B366 Monel 400 Buttweld Fittings, you’re choosing components that meet globally accepted quality and safety requirements.
