LANCASTER ALLOYS COMPANY OFFERS A NON CONVENTIONAL SOLUTION TO A CONVENTIONAL PROBLEM IN THE MANUFACTURE OF NICKEL ALLOYS

Through the years, welding of nickel filler metals to parts of nickel based alloys has been somehow unpredictable. This is mostly due to the way commercially produced nickel alloys welding wires are drawn. The commercial type of drawing, using lubricants, grease or drawing compounds, imbeds them underneath the surface of the wire as it is being “pulled” through dies in the reduction process. This, in turn, causes sub-surface contamination which usually leads to an unstable weld with porosity, cracks and uneven uniformity. Lack of cleanliness and a wide variety of impurities in nickel alloys are the major reasons for rejection of the welds.

TECHNICAL DATA SHEET 4130 VM PER AMS6457

Nominal Chemistry for AMS6457: 0.95 Cr, 0.20Mo, 0.30 C, Balance Fe

SCOPE

The vacuum melted bare welding wire 4130 VM per AMS6457 – low alloys steel – is widely used in aerospace and many other critical applications to achieve lighter weight and improve weldability in highly stressed joints of low alloy steel structures,which are capable of being heat treated to a minimum tensile strength of 180,000 psi.

One of the many wires we manufacture includes 17-22A(S) per AMS6458 – vacuum melted (VM), bare (copper free surface), low alloy high strength welding wire.
