Product Description

Density: 9.7g/cm3Min.

Chemical composition: Mo-1 99.95%Min.

This product is made of molybdenum powder FMo-1 with the addition of trace element.

The surface have no defects, such as superfusion, blister, divided layer, crackle,etc.

Characteristic:

The high temperature molybdenum mandrels have been developed by our company and the materials science & engineer Institute.The R&D crafts include selecting and mixing raw materials which are compressed into embryos material,sintering in the intermediate frequency furnace in 1850-1950°C and then turning and molding.The average density of the products is more than 9.7g/cm³.Compared with the common molybdenum mandrels,the density improves 2%-6%,the Vickers hardness reaches above 350kg/mm² and the abrasion resistance increase 60%-80%

Additional composition

Ti(1.0~2.0)%, Zr:(0.1~0.5)%, C: (0.1~0.5)% and other trace element. Chemical composition

Main applications:

Mainly used for piercing steel tubes, such as stainless steel tubes, high-temperature alloy steel and seamless steel tube, etc.
