Precision alloys

This page contains the description of these alloys: physical and mechanical properties, applications, grades and types of products.

Main information

A large group of metal high alloys with a precise chemical composition and set physico-mechanical properties.

Classification

Grades

In compliance with GOST 10994-74, the alloy grade (except thermostatic bimetals) includes a two-digit number that designates the average weight percent of the element and the letter of the element after the number. Iron is not stated in the alloy grade. In the thermostatic bimetal grade the weight percent is stated after the element number (so as for ordinary steel). Letter “A” at the end of the grade means strict requirements towards metal purity. Letter “E” means that the alloy is hard-magnetic.

Designation Element
Mn Manganese
Si Silicon
Cr Chromium
Ni Nickel
Cu Copper
N Nitrogen
V Vanadium
Nb Niobium
W Tungsten
Se Selenium
Co Cobalt
Be Beryllium
Mo Molybdenum
B Boron
Ti Titanium
Al Aluminum
Zr Zirconium
P Phosphorus
Ch Rare-earth metals


Additional alloy cleaning methods are applied for reaching high-purity:
  • vacuum-induction melting;
  • electron-beam smelting;
  • plasma remelting;
  • electroslag remelting;
  • vacuum-arc remelting.

The grades of such alloys contain the following letters: VI, EB, P, ES and VA correspondingly.
