Alloy ХН70 (ЭИ442)
Designation
Description
Alloy ХН70 used: for the manufacture of ribbons with thickness of 0.12 and 0.40 mm and a width of 380 and 400 mm used for parts of the pipeline systems operating under moderate stress conditions of very high temperatures (up to 1100−1200 °C) and other branches of engineering.
Note
Heat-resistant Nickel-based alloy.
The alloy is practically homogeneous structure of the solid solution after heat treatment (heating up to 1000−1200 °C With cooling in water or air).
Besides a sufficient manufacturability (prokativaet, stonemont, weldability) and high resistance to gas corrosion (okalinolomatel) alloy has good thermal fatigue resistance (thermal stability).
Standards
Chemical composition
Ni is the basis.
According to TU 14-1-2861-79 the content of residual elements is regulated in accordance with GOST 5632.
