ASTM B335 Standards And Specifications

ASTM B335 specification covers Hastelloy B2 Round Bar and Rods.

ASTM B335 Round

Astm B335 Round Bar

ASTM B335 Round Bar is a solid solution strengthened, nickel-molybdenum material, with significant resistance to reducing environments like hydrogen chloride gas, and sulfuric, acetic and phosphoric acids. Molybdenum is the primary alloying element which provides significant corrosion resistance to reducing environments. This nickel steel alloy can be used in the as-welded condition because it resists the formation of grain-boundary carbide precipitates in the weld heat-affected zone. This nickel alloy provides excellent resistance to hydrochloric acid at all concentrations and temperatures. In additions, Hastelloy B2 has excellent resistance to pitting, stress corrosion cracking and to knife-line and heat-affected zone attack. Alloy B2 provides resistance to pure sulfuric acid and a number of non-oxidizing acids.

Scope And Manufacturing

ASTM B335 specification covers rod of nickel-molybdenum alloys of N10665 (Hastelloy B2) for use in general corrosive services. The material shall conform to the required chemical composition for nickel, molybdenum, iron, chromium, carbon, silicon, cobalt, manganese, phosphorus, sulfur, vanadium, nickel, molybdenum, aluminum, columbium, copper, tantalum, titanium, tungsten, zirconium, and magnesium. The alloys shall conform to the required mechanical properties such as tensile strength, yield strength, elongation, and Rockwell hardness.
