TZM--a high temperature molybdenum alloy
TZM--a high temperature molybdenum alloy
TZM is the commercial designation for the most important of the high-temperature molybdenum alloys. It contains approx. 0.5%Ti, 0.08%Zr and 0.01-0.04%C.
Storage
TZM may superficially oxidize when stored in humid rooms or in regions with high atmospheric humidity. It should always be stored in dry rooms where temperature variations are at a minimum. Oxidized TZM can be cleaned chemically as described in the chapter on pickling.
TZM sheets
Cold-rolled TZM sheets are produced in thicknesses from 0.1 to 0.5mm and hot-rolled TZM sheets are produced in thicknesses from 0.5 to 4.0 mm. Cold-rolled sheets have a bright surface. Cold-rolled sheets which have the optimum surface finish are produced in the following qualities:
1.Standard quality, 2.Stamping quality, 3.Deep-drawing quality, 4.Etching quality;
Molybdenum sheets can be supplied as-rolled or stress-free annealed.
