New superalloy for pipelines of high temperature heat exchangers in high temperature helium reactors

Description

A new superalloy of Ni-20Cr-20W type was developed to be used as a material for heat exchangers operating at 950<de<C in high temperature helium cooled nuclear reactors. The alloy has high short-term mechanical properties and stable properties up to 1000<de<C. Long-term rupture strength (10000 h) at 950 deg C constitutes 250 MPa. The alloy metallurgy includes vacuum-induction melting, tube pressing, welding, cold working. Welded joints tests within the range of 900 to 1000 deg C show that their mechanical properties are similar to those of basic metal. 2 refs.; 3 tabs
