Hastelloy B-2 (Tech Center of Shanghai HY Industry Co., Ltd)
Outline of Hastelloy B-2 properties and applications.
Nickel-molybdenum amalgam hastelloy B2 has an exceptionally low carbon and silicon content, which decreases the precipitation of carbon and other pollution gradually works in the weld heat impacted zone, and in this way the weld crease has adequate consumption obstruction. It additionally has great protection from consumption in decently focused sulfuric corrosive arrangements (or those containing a specific measure of chloride particles). They can likewise be utilized in acidic and phosphoric corrosive conditions. Combinations have the best erosion opposition just when they are in a reasonable metallurgical state and have an unadulterated precious stone design. It has a wide scope of uses in the synthetic, petrochemical, energy assembling and contamination control fields, particularly in the sulfuric, hydrochloric, phosphoric and acidic corrosive businesses.
Hastelloy B-2 Alloy minimum mechanical properties in the room temperature:
Tensile strength Rm N/mm2
Yield strength RP0.2N/mm2
Elongation A5 %
Hastelloy B-2 metallographic structure
Hastelloy B2 is a face-focused cubic grid structure. By controlling the iron and chromium content to a base, the interaction weakness is decreased and the precipitation of the Ni4Mo stage somewhere in the range of 700 and 870°C is forestalled.
ought to be warmed as fast as conceivable to the necessary temperature. Hot handling temperature range 1160 ℃ ~ 900 ℃.
Normal size of the grain size of the composite is firmly connected with the level of deformity of the forgings and the last producing temperature.
Grip of the compound surface oxide, oxide tone and weld slag around the weld is more grounded than hardened steel, it is prescribed to utilize fine grain grating belt or fine grain rough wheel for crushing.
Composite ought to be machined subsequent to toughening, because of the great pace of work solidifying of the material, so it is prudent to utilize a lower cutting pace and weighty feeder than the handling of low-amalgam standard austenitic treated steel for handling, to cut into the virus work solidifying of the surface layer underneath.
