44NKHTJU ribbon, round, wire
All materials are precision type are of high quality and stringent requirements for a fixed chemical composition, which fully determines the basic performance of the raw materials. Properties and operational parameters of such alloys are divided into several basic types. Each type has its own unique features and individual applications.
Features alloy 44 NHTU
Alloy 44NKHTJU is strictly regulated parameters of elasticity and hardness. This feature is achieved thanks to the successful combination of the elements included in the composition of the material. And of equal importance here is not only the existence of one or another component, but the proportion of a combination of important substances. Like all other precision alloy type, such raw material is of incidental impurities and additions, and high surface quality is another added advantage when used. The main scope of alloys of this type is the manufacture of elastic elements of high sensitivity, operating at temperatures up to two hundred degrees.

Indicators of weldability
The alloy has limitations in terms of weldability | The welding process requires some advance preparation (preheating contacting surfaces to one hundred or one hundred and twenty degrees, and subsequent heat treatment suture zone) |
The welded alloy has no restrictions | Not require additional surgery |
Difficult weldable material | The necessary heating of the contact surfaces up to a few hundred degrees, the subsequent annealing and heat treatment after welding process |
