Hastelloy W

Hastelloy W is a solution-reinforced, super heat-resistant nickel-based alloy that is used primarily as a filler metal for welding different alloy materials. Alloy W has a wide variety of excellent welding properties and is used extensively in the gas turbine, aerospace and chemical industries. The different welds welded with alloy W are determined by the properties of the base material and are commonly used in most welding combinations.

Hastelloy W corresponding grades: Hastelloy W, UNS N10004 - A very good choice of filler metal for welding different alloys - Resistant to cracking when welding precipitation hardening alloys - Resistant to oxidation temperatures up to 760°C - Low coefficient of thermal expansion Main applications for Hastelloy W - Welding of precipitation-hardening alloys that are sensitive to fracture - Rings for gas turbine engines
