All the materials

The quality of materials and manufacturing techniques applied underlie mechanical, chemical, thermal and electric fastening features. Satinox Assemblage uses a full range of all available materials to find solutions for high-precision applications in terms of resistance to compression, traction, cutting, twisting, bending, rubbing, shock (resilience), deformation (ductility) and extremely high and extremely low temperatures in corrosive, abrasive, acid, basic or alkaline environments.

back to topSteel and stainless steel

Steel is an alloy made of iron (Fe) and carbon (C). The different grades of steel are the result of a defined production procedure (quenching, lamination, forging) plus the integration of appropriate quantities of additional elements: aluminium (Al), chromium (Cr), cobalt (Co), manganese (Mn), molybdenum (Mo), nickel (Ni), niobium (Nb), lead (Pb), silicon (Si), sulphur (S), titanium (Ti), tungsten (W), vanadium (V). Each grade of steel has its own particularity: elasticity, hardness, resilience, weldability, ductility, etc.

Steel can be graded according to several standards. The steel references given above as examples fall under the following standards: Afnor NF A 35573 (France), EN 10027 (Europe) or AISI (United States). For fastenings, there are specific standards. For example, ISO 3506-4:2003 specifies the mechanical characteristics of sheet metal screws made from austenitic, Martensitic and ferritic stainless steels which are corrosion-resistant when tested at room temperature (between 15°C and 25°C). The other standards classed E25-100 apply to other fastening elements: screws, pins and grub screws in other conditions.

limited welding resistance good weldability good weldability
Use For factory elements, limited corrosion and acid resistance Standard quality The highest level of corrosion resistance (+ molybdenum supplement) steel springs in chromium Martensitic C1, C2, C3 have limited corrosion resistance compared to A2, A4.

Regarding fastenings and assembly materials, the manufacturing techniques are also the basis of mechanical properties. With identical materials, items manufactured by hot forging (or heat stamping) offer far better performances than the cut versions. Hot forging produces a finishing of exceptional quality all the way through. Contrary to cutting, this hardening method respects the linear fibre structure to preserve and even improve the basic mechanical properties of the material.

back to topOther metals and alloys: copper, nickel, aluminium, titanium, chromium, vanadium

Copper and its alloys are generally used for their electric conductibility and amagnetistic properties, good corrosion and cryogenic temperature resistance. For fastenings, we mainly use:

  • brasses: copper-zinc
  • bronzes: copper-tin ( Arcap )
  • nickel silvers: copper-nickel-zinc ( ex. CuZn17Ni26 )
  • cupro nickels: copper-nickel ( Monel® )

For the materials, as for the rest, aeronautic fastenings have specific properties. We use:

  • Waspaloy : a nickel-chromium alloy
  • Nimonic 90 : a nickel-chromium-cobalt alloy for high temperatures (950°C)
  • A286 steel: an iron-carbon-chromium-nickel alloy for high temperatures (650°C)
  • Inconel 718 and Inconel X-750: nickel-cobalt-chromium alloys
  • Titanium TA6V: a titanium-aluminium-vanadium alloy
  • Beryllium copper: a copper-beryllium alloy (CuBe 1.9 / UBE2)
  • Hastelloy: a highly acid-resistant nickel-molybdenum-iron-chromium-cobalt alloy
  • Incoloy: a very strong and anti-oxidizing nickel-iron-chromium alloy
  • Aluminium and its alloys for welding (hot forging)
    • Aluminium bronze alloys: copper-aluminium (series 2000) AU4G can reach a hardness comparable to that of special steels
    • Magnesium-aluminium alloys (series 5000) AG3 AG5 which are easy to welder
    • Zinc-aluminium alloys (series 7000) such as AZ5GU or 7075 which have high mechanical resistance

back to topOther materials: plastic, ceramic, cardboard, etc

In certain particular cases, fastenings are made from non-metal materials. We use:

  • White and black nylon for electronic applications
  • PTFE Polytetrafluoroethylene ( Teflon® ) for chemically aggressive environments
  • Ceramics such as silicon nitride Si3N4 for hardness and high-temperature resistance
  • Bakelized cardboard or hard cardboard for washers
