Stainless alloy 08Cr17T (EI 645) is designed for the manufacture of products that work in oxidizing environments of chemical synthesis. The alloy is also used where there is a risk of pitting, in atmospheric humidity, sea water, as well as in the manufacture of heat exchangers and welded structures that are not subject to shock loads and operated at temperatures not below -20 ° C, in the manufacture of equipment, soap, brewing, food processing and light industry. It is used as a cladding layer in the production of hot-rolled two-layer stainless steel sheets.

Technological properties of 08Cr17T grade alloy

Tendency to temper embrittlement 08Cr17T has a tendency to temper embrittlement at temp.+475 °C.
Peculiarities of heat treatment Welded products made of 08Cr17T must be annealed at 720-780°C for 2 hours, air cooling. Parts belonging to the ferrite class should be subjected to heating to. 760-780 ° C, air cooling and ageing on the calculation - 1 mm of maximum alloy thickness 30 min + 1 min to achieve maximum ductility, and eliminate the tendency to IBC. tempering of products to 450-555 ° C is not allowed - this will lead to brittleness.
Weldability For automatic submerged-arc welding of ANF-14, AN-26 wires Sv-05Kh25N12Tu and 08Kh20N9G7T are used. Limited weldable steel. Mechanical satisfactory qualities are obtained during welding of products with insignificant thickness up to 3 mm.
Forging temperature. Air-cooled at a cross-section not exceeding 350 mm. The beginning - 1220 °C, the end - 900 °C.
