Alloy Steel S42900 45 Degree Elbow Pipe Fittings Connection
This is a nickel-base alloy that was originally developed as a container material for molten fluoride salts, to which it has good resistance in the
temperature range 1300 to 1600ºF (705 to 870ºC).

Application
As previously mentioned, the alloy is mainly used as a container material for molten fluoride salts.
MACHINABILITY
The alloy work hardens rapidly, generates high heat during cutting, welds to cutting tool surface and offers high resistance to metal removal because of its high shear strength.
Machines should be rigid and overpowered as much as possible
Workpieces and tools should be held rigid.
Tools must be sharp: carbide tipped should be used for most applications but high-speed steel tools may be used for short production runs.
Heavy, constant feeds should be used.
WELDABILITY
This alloy may be welded by the gas-metal-arc, gas-tungsten-arc and shielded-metal-arc processes. Parts may normally be used in the as-welded condition, but a post-weld anneal will result in optimum corrosion resistance.
