Sheets and boats made from nickel alloy
JSC POLEMA manufactures precision-alloy products of the grade Ni67Mo28-PM (type NIMO-28):
- hot-rolled sheets for producing boats and other components for use in aggressive environments and at high temperatures;
- boats for reduction furnaces.
Alloy chemical composition (%, mass.):
- molybdenum 27-28;
- iron 6-7;
- remainder - nickel.
Sheets from Ni67Mo28-PM
Hot-rolled sheets from Ni67Mo28-PM grade alloy are produced with a thickness of between 2.0 and 6.0 mm, a width of between 200 and 400 mm and a length of between 300 and 900 mm. Actual dimensions and acceptable size deviations are established on an order-by-order basis.
The following mechanical characteristics are controlled for sheets with a thickness from 2.0 to 4.0 mm: tensile strength of at least 80 kg/mm2 and a relative elongation of at least 20%.
The sheets are delivered without surface etching.
Boats from Ni67Mo28-PM
The shape and dimensions of boats made from Ni67Mo28-PM (NIMO-28) grade allow are determined based on the client's drawings.
