Hastelloy B-3 Forged Bar

Chemical Composition

Chromium sits deliberately between 1.0 and 3.0% in this forged bar, and that addition is what separates the UNS N10675 window from the earlier nickel-molybdenum grades. Consequently, molybdenum holds 27.0–32.0% while carbon stops at 0.01%, so the nickel-plus-molybdenum total of this forged bar lands between 94.0 and 98.0%.

Mechanical Properties

Minimum room-temperature values below come from the rod table of ASTM B335 for UNS N10675. Consequently, the ordered state and the section size govern final acceptance of Hastelloy B-3 forged bar.

• ASTM B335 carries this grade inside a scope that reaches five nickel-molybdenum numbers, and its rod title means the table speaks in diameters from 7.94 mm through 88.9 mm. Besides, the hardness cell printed beside N10675 in Table 2 stands empty, so no hardness acceptance figure exists for us to quote. Consequently, work above that diameter window moves onto the ASTM B564 forging route, and we agree the test position there instead of assuming it.

Physical Properties

Reference data places the density of this forged bar at 9.22 g/cm³, with a melting range that closes near 1418 °C. Moreover, the annealed matrix leaves this forged bar essentially non-magnetic, and its elastic modulus settles near 216 GPa.

Meanwhile, the physical properties table on the Hastelloy B-3 material page holds the conductivity and expansion figures behind this forged bar.

Heat Treatment

The water-quenched anneal is the specification-defining step behind this Hastelloy B-3 forged bar, because Ni3Mo forms close to 650 °C and only a rapid quench after 1066 °C restores the corrosion resistance. Moreover, a section strained past roughly 7% at the outer fibre returns to that anneal before it can go back into a weld.

Standards

Sections above the rod ceiling of this forged bar run to ASTM B564 from ASTM International, because the Ni-Mo row of that document's alloy-type table names N10675 for forgings. Moreover, ASTM B462 reaches flanges and forged valve parts of this forged bar for acid-plant duty. Besides, ISO 9725 and DIN 17754 carry the international and European forging routes, while no aerospace document reaches this grade in any product form.

Finally, the full standards list on the Hastelloy B-3 material page adds the plate, tube, fitting and flange documents plus the Chinese designation behind this forged bar.

Dimensions

Dimensions of Hastelloy B-3 forged bar follow the route, the document and the order quantity. Therefore, typical supply ranges sit in the table below, so please confirm your sizes in the inquiry.

Available sizes of this Hastelloy B-3 forged bar depend on the route, the document, the state and the lot size. Please confirm the size, section and length you need for this forged bar in the inquiry.

Forged sections of this grade are quoted to ASTM B564, whose Ni-Mo alloy row names N10675 for forgings, alongside ASTM B462 for flanges, forged fittings and valve parts. Moreover, ISO 9725 and DIN 17754 carry the international and European routes, and the reduction plan is agreed before the ingot is worked.

Surface Finishes

The surface you order decides how this forged bar behaves once it reaches a hydrogen chloride synthesis unit, an absorption tower or an acid regeneration loop. Moreover, most stock of this forged bar leaves the yard solution annealed and pickled. Therefore, we confirm the finish and the straightness band on this Hastelloy B-3 forged bar before we write the offer.

In addition, the surface finishes table recorded on the Hastelloy B-3 material page lists the remaining conditions quoted for this forged bar.
