Composition, properties, application

Steel brand 42NKHTJU is a precision iron-Nickel alloy with given elastic parameters. The alloy used for the production of elastic sensing elements operating at temperatures up to 1000 C.

Chemical composition

Component Fe Ni Cr Ni Al Si, Mn C
The percentage 44,91…49,30 41,5 43,5… 5,3 5,9… 2,4…3,0 0,5…1,0 0,5…0,8 Not more than 0.05

In the alloy 42NKHTJU allowed the presence of such non-metallic impurities such as sulfur and phosphorus. Their percentage content in the final product cannot be more than 0,020%.

Physico-mechanical characteristics of the alloy

  • Tensile strength, MPa — 1200…15700 C;
  • The plastic limit, MPa — 800…1000;
  • Relative tensile elongation, % — 13;
  • The relative narrowing in the transverse secanim, % — 25;
  • Brinell hardness number — 320…350 HB.

Heat treatment

The alloy may be subjected to heat treatment — tempering (t° 910°C) and aging (t° of 600°C).

Assortment

The tape of this alloy produced according to technical standards GOST 14117−85, and the leaves are produced in accordance with the requirements of GOST 42082−78.
