Properties of Hastelloy B2 alloy

Hastelloy B2 Cold Forming

Cold forming process plays a very important role in the desired product formation.The process involves rolling, pressing forging of the metal with desired procedure. Cold forming is always done with precaution and under expertise with a clean environment. It increases the strength of the metal and gives hardness a new level.

Hastelloy B2 Hot Forming

While performing hot forming process in a Hastelloy, the temperature should be maintained with the furnace.The preheating of the furnace should be done so as to make the shape of the metal proper.The size and thickness of the metal play a very important role while hot forming so the metal can have the proper size.Re-heating is necessary to maintain the correct hot forming temperature, and dies of the metal should be heated to avoid extreme chilling of the surfaces.

Hastelloy B2 Machining

When Machining Hastelloy B2 the material gets work-harden quickly, produce high heat during cutting weld to the cutting tool surface and offer high resistance to metal removal because of their high shear strengths. The machine should be rigid and overpowered as much as possible.The workpiece and tool should be held rigid. The tools used should be sharp while machining. The machine used, should be heavy, constant, feeds to maintain the positive cutting action. If feed slows and the tool dwells in the cut, work hardening occurs, tool life deteriorates and close tolerances are impossible.

Hastelloy B2 Welding

Hastelloy B2 has a good welding property. The welding process is done by methods such as common arc welding process, plasma arc welding (PAW), resistance spot welding (RSW), laser beam welding (LBW), and electron beam welding (EBW) are used. The pitting corrosion resistance of the metal can be welded to be reduced due to micro-segregation of main molybdenum during solidification.

Hastelloy B2 Heat Treatment

Before heat treatment, make absolutely sure that grease, graphite, and other foreign materials are removed from all surfaces. The annealing procedure has been designed to place the material in the optimum condition with respect to mechanical properties and corrosion resistance. Annealing is often performed after cold working operations to restore ductility and lower the yield and ultimate tensile properties. In general, the only heat treatment that is acceptable for these alloys is a full solution anneal.
