TU 6365-004-46594163-2000 Multilayer strips AlFeSi-St-AlFeSi.P and AlFeSi-St-Ni.P.

Technical Requirements 

Description

Multilayer bimetal strip, grade AlFeSi-St-Ni, made of low-carbon steel strip clad with aluminum alloy on one side and nickel on the other side.

Composition

ferrous-and-silicon-aluminum-steel-nickel-en
  • Base – low-carbon quality steel grade DC04 with chemical composition acc. to GOST 9045.
  • Coating – aluminum alloy AlSiFe with chemical composition acc. to TU 1811-019-00195592-2000 or aluminum alloy grade 8011 with chemical composition acc. to GOST 618.
  • Coating – nickel Ni99,6 with chemical composition acc. to GOST 492.

The thickness of cladding layers h1 and h2 is the same for both sides and varies from 5 to 8% of the finished strip thickness. Upon customer’s request, the thickness of the cladding layer can be up to 10% on each side.
