Length: Custom cutting available

Surface Finish: Bright, Black, Pickling, Polishing

Brand: DELTA

Services: Cutting, Polishing

Minimum Order: 2 Kgs

Other Forms: Bar, Strip, Coil, Pipe, Sheet, Plate, Wire

Material Properties & Advantages

Chemical Composition: Nickel (min 62%), Molybdenum (26-30%), Low Carbon (max 0.02%)

Hastelloy B-2 round bars excel due to their unique chemical composition and microstructural stability. Molybdenum forms a dense protective oxide layer that prevents oxidation and chemical attack, with self-healing properties that restore protection if damaged.

Key mechanical properties include:

Tensile Strength: 690 MPa (100 ksi) minimum
Yield Strength: 310 MPa (45 ksi) minimum
Elongation: 40% in annealed state
Temperature Resistance: Up to 1093°C (2000°F)
Cryogenic Performance: Excellent ductility and toughness

Available Sizes & Standards

Note: Diameters larger than 300 mm available on custom order. Surface finishes include hot-rolled (black) and cold-drawn (bright) options.

Key Applications

Chemical Processing: Heat exchangers, reaction vessels, and piping systems handling concentrated acids
Oil and Gas: Wellhead components, downhole tools, and offshore platforms resistant to sour gas and saltwater
Pharmaceutical & Food Processing: Reactors and processing equipment compliant with FDA regulations
Marine Engineering: Propeller shafts, seawater cooling systems, and offshore wind turbine components

Quality Assurance & Services

Our Hastelloy B-2 round bars are produced using advanced melting processes (vacuum induction melting and vacuum arc remelting) to ensure chemical homogeneity. Each batch includes material test reports certifying compliance with international standards.

Additional services include precision machining, heat treatment, surface coating, and custom fabrication to meet specific application requirements.
