Use

Alloy stainless steel 08KH17T (PT 645) is designed for the manufacture of products that operate in oxidizing environments of chemical synthesis. The alloy is also used where there is a risk of pitting corrosion, in atmospheric moisture, sea water and also in the manufacture of heat exchangers and welded structures, not exposed to shock loads and is operated at a temperature not below -20°C, production equipment, soap-making, brewing, food industry and light industry. It is used as a cladding layer in the production of two-layer hot rolled stainless steel sheets.

Technological properties of grade 08KH17T

The tendency to temper brittleness 08KH17T has at the temperature.+475 °C inclination and long exposures to the fragility of the holiday.
Features of heat treatment Products welded 08KH17T should be subjected to at 720−780 °C annealing for 2 hours, air cool. Details relating to the ferritic class should be subjected to heating up to. 760−780 °C, air cooling and aging for the calculation is 1 mm, the maximum thickness of alloy 30 min + 1 min to reach the maximum ductility, as well as to eliminate the tendency to MKK. the release of products carried out at 450−555°C is not acceptable — it will lead to fragility.»
Weldability For automatic arc welding under flux ANF-14, an-26 used wire SV-05Х25Н12ТЮ and 08Х20Н9Г7Т. Limited-weldable steel. Mechanical satisfactory quality is produced during welding products, with negligible thickness up to 3 mm.
