Description

Alloy AT3 is used: for the manufacture of semi-finished products (sheets, strips, foils, strips, plates, bars, rods, profiles, tubes, forgings and forged blanks) by the method of deformation, and also ingots; vessels and equipment chemical industry, working under cyclic loads and temperatures up to +350 °C; pins and tool in medicine.

Note

The alloy possesses in comparison with other commercial alloys (including VT1−0) higher corrosion resistance (environment-pharmaceutical, food industry, sea water). The advantages of the alloy should be attributed to its higher (compared to VT1−0) antifriction properties.
