Hastelloy B2 could be a solution strong, nickel-molybdenum alloy, with vital resistance to reducing environments like acid gas, and chemical element, carboxylic acid and phosphorous acids. Mo|metal} is that the primary alloying element that provides vital corrosion resistance to reducing environments. This alloy steel alloy will be utilized in the as-welded condition as a result of it resists the formation of grain-boundary inorganic compound precipitates within the weld heat-affected zone.
This alloy provides glorious resistance to acid the least bit concentrations and temperatures. additionallys, Hastelloy B2 has glorious resistance to corrosion, stress corrosion cracking and to knife-line and heat-affected zone attack. Alloy B2 provides resistance to pure acid and variety of non-oxidizing acids.
Limiting Factors of Hastelloy B2
Alloy B-2 has poor corrosion resistance to oxidizingenvironments, therefore, it's not counseled to be used in oxidizing media or within the presence of metallic element or metallic element salts as a result of they'll cause speedy premature corrosion failure. These salts could develop once acid comes involved with iron and copper. Therefore, if this alloy is employed in conjunction with iron or copper piping in an exceedingly system containing acid, the presence of those salts might cause the alloy to fail untimely. In addition, this alloy steel alloy mustn't be used at temperatures between 1000° F and 1600° F thanks to a discount within the malleability within the alloy.
