01Н17К12М5Т-YL, ЭП845-IL tape, sheet, round, wire


Accessory alloy 01Н17К12М5Т-IL (ЭП845-YL) to a group of structural steel special purpose Maraging class allows you to use it for the manufacture of parts operating under the most severe conditions. Thanks to the optimal technological and operational parameters such material to cope with the heavy work and actively oppose the influence of the most extreme industrial factors, providing reliability and durability of the equipment.


The percentage of Nickel in the alloy can range from 17 to 18 percent, and the proportion of cobalt is 11.5 to 12.5%. To increase the operating parameters material legarrette additives of molybdenum, titanium, silicon, and some others.

The percentage 01Н17К12М5Т-IL (ЭП845-YL) GOST 5632−72.
