What is the difference between Hastelloy B and C?

Hastelloy B is known for its resistance to HCl (hydrogen chloride) and for its creep and rupture strength at temperatures around 1,400°F. Hastelloy C also resists oxidizing and reducing atmospheres at temperatures up to 2,000°F, and can still carry loads at temperatures to 1,600°F.

What is Hastelloy B?

Hastelloy B covers a range of different highly corrosion-resistant alloys with the primary alloy metal being nickel. Hastelloy survives under high temperature services to severe service. It can handle hydrochloric acids at all concentrations and temperatures.

What kind of metal is Hastelloy?

Hastelloy X is a solid-solution-strengthened nickel-chromium-iron-molybdenum alloy that combines good oxidation resistance, high-temperature strength and exceptional stress-corrosion resistance which makes this alloy also interesting for petrochemical applications.

What is the composition of Hastelloy?

The Hastelloy alloy composition includes molybdenum, chromium, iron, tungsten, cobolt, manganese, copper, vanadium, phosphorus, silicon and sulfur. Depending on the grade and standards of the alloy, the composition differs. Each of these classes and grades has specific characteristics and applications.

What is Hastelloy C used for?

Hastelloy C-276 Welding Material Alloy C276 welding products are used as matching composition filler material for welding C276 alloy wrought and cast products, for dissimilar welding applications including other nickel-chromium-molybdenum alloys and stainless steels, and for weld overlay or cladding of steels.

Does Monel 400 rust?

Although Monel-400 is known for its ability to stand up to tough corrosive elements, pitting corrosion of Monel-400 occurs when it is exposed to stagnant salt water such as seawater [5]. The corrosion rate of this alloy decreases sharply with increasing nickel content in the alloy.

What kind of steel is Hastelloy B3 alloy?

B-3 alloy has excellent resistance to pitting corrosion, to stress-corrosion cracking and to knife-line and heat-affected zone attack. HASTELLOY B-3 alloy is available in the form of plate, sheet, strip, billet, bar, wire, pipe and tubing. Bar: ASTM B 335, ASME SB335, (DUAL CERTIFIED TO ASTM B564, ASME SB564 ON 3-1/2 DIA.

Which is the best grade of Hastelloy alloy?

Excellent stress corrosion cracking resistance with very good resistance to localized attack. C-2000 Like all Hastelloy grades, 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.

What are the properties of Hastelloy C-2000 alloy?

C-2000 Like all Hastelloy grades, 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. C-22 The Hastelloy C-22 properties make it particularly resistant to pitting and crevice corrosion.
