ASTM B564 / ASME SB564 Hastelloy C276 Flange With Welded Tube

ASTM B564 / ASME SB564 HASTELLOY C276 FLANGE WITH WELDED TUBE

The Corrosion-Resistant hastelloy alloys are widely used by the chemical processing industries. The need for reliable performance leads to their acceptance and growth in the areas of energy, health and environmental, oil and gas, pharmaceutical and flue gas desulfurization industries.

Hastelloy Alloy possesses outstanding resistance to non-oxidizing acids, such as hydrochloric acid and sulfuric acid. The advantages of Hastelloy B-3 alloy over previous B-family alloys are enhanced thermal stability and improved fabrication characteristics.

The attributes of Hastelloy alloys include

1. High resistance to uniform attack
2. Outstanding localized corrosion resistance
3. Excellent stress corrosion cracking resistance
4. Ease of welding and fabrication

The most versatile of the Hastelloy alloys are the "C-type". Hastelloy c alloys include

1. C-276 A Versatile, corrosion resistant alloy. It has very good resistance to reducing, and mildly oxidizing corrosives. Excellent stress corrosion cracking resistance with very good resistance to localized attack.
2. C-2000 Like all Hastelloy grade, the C-2000 alloy combines outstanding resistance to oxidizing media with superior resistance to non-oxidizing environments and represents a true performance breakthrough for chemical process equipment applications.
3. C-22 The Hastelloy C-22 properties make it particularly resistant to pitting and crevice corrosion. Moreover, it has been used extensively to protect against the most corrosive FGD systems and the most sophisticated pharmaceutical reaction vessels.
