Hastelloy B3 Round Bar
Hastelloy B3 Rod is a nickel-molybdenum alloy known for its excellent corrosion resistance, especially in reducing environments such as hydrochloric and sulfuric acids. It is widely used in various industrial fields where high performance and corrosion resistance are essential.
What is the difference between Hastelloy B2 and B3 alloy rods?
The main difference between Hastelloy B3 and B2 rods is corrosion resistance. Hastelloy B3 has excellent corrosion resistance in hydrochloric acid at all concentrations and temperatures, while Hastelloy B2 has a moderate corrosion resistance.
What is Hastelloy B3 Alloy Rod used for?
Hastelloy B3 Rod is a nickel-molybdenum alloy that is particularly suitable for equipment that handles reducing chemical environments. It is widely used in chemical process industries involving sulfuric acid, phosphoric acid, hydrochloric acid and acetic acid.
What is the chemical composition of B3 alloy rod?
B-3 alloy rod is a nickel-molybdenum solid solution strengthened high temperature alloy with a nominal chemical composition of 65% nickel and 28% molybdenum, with additions of iron, manganese, tungsten and cobalt. It is usually sold under the trade name Hastelloy B-3 and the common name is UNS N10675.
