Alloy ХН57КВЮТМБЛ used: for the production of cast bars in a vacuum-induction remelting for the manufacture method of equiaxed casting of shaped castings of parts of power engineering, operating at temperatures up to 1150 °C.
High-temperature Nickel-based alloy with hafnium.
|Bars and shapes||В32||TU 14-1-4828-90|
According to TU 14-1-4828-90, the chemical composition is given for the alloy grade KhN57KVYUTMBL-VI (Chs88-VI). Boron, zirconium, yttrium and cerium are introduced into the metal by calculation and chemical analysis are not determined. It is possible to estimate the mass fraction of arsenic in points on the scale of spectral analysis - the mass fraction of arsenic should be no more than 1 point.
|Particularities of production of goods||Cast bars on the other 14-1-4828-90 are supplied with a diameter of 95 mm with a solid abrasive Stripping. On the surface of bars allowed in: oxide films, contamination, inclusion of foreign metal as well as afloat, increasing the size of bars. Quality control of the surface subjected to each rod according to agreed standards.|
