Hastelloy B3 UNS N10675 Tube

Hastelloy B3 (N10675)

Hastelloy B3 (N10675) is a nickel-based superalloy composed of nickel, molybdenum, cobalt and other elements, with a nickel content of about 65%. Hastelloy B3 (N10675) nickel-based alloy material is a new material improved on the basis of Hastelloy B2, which improves the thermal stability of the material, thereby improving the corrosion resistance, and at the same time improving the hot forming and cold forming performance. In recent years, it has been increasingly used in the production and manufacture of chemical equipment.

The mechanical properties of Hastelloy B3 (N10675) Hastelloy plate in solid solution state: as the heating temperature rises, its tensile strength, yield strength and elastic modulus will decrease, while elongation, thermal expansion coefficient, thermal conductivity and specific heat will increase slightly High; and with the increase of the cold deformation rate, the hardness, tensile strength and yield strength increase, and the elongation decreases.

Chemical Composition

Heat Treatment

Hastelloy B3 (N10675) It is very important that the workpiece should always be kept clean and free from contamination before and during heat treatment. During the heating process, the workpiece cannot touch sulfur, phosphorus, aluminum and other low-melting point metals, otherwise it will damage the properties of the alloy and make the alloy brittle. The heating furnace is an electric furnace. If a gas or oil furnace is used, the lower the sulfur content in the fuel, the better. According to the data, the total sulfur content in natural gas and liquefied petroleum gas is not more than 0.1% (V), and the sulfur content in city gas The content of sulfur in fuel oil should not exceed 0.25g/m3, and the sulfur content in fuel oil should be less than 0.5% (W).
