Invar 36(FeNi36,Nilo 36,Alloy 36,1.3912,NAS 36,UNS K93600) Seamless Pipes Tubes Welded Piping Tubings

We are professional Invar 36(FeNi36,Nilo 36,Alloy 36,1.3912,NAS 36,UNS K93600)Controlled Expansion Alloys  Seamless Pipes Tubes Welded Piping Tubings factory from china

Alloy 36 (NILO 36, INVAR 36) is a Nickel-Iron, low expansion alloy which contains 36% Nickel. Invar 36 has a low coefficient of expansion from cryogenic temperatures to about +500°F (260°C). Invar 36 also retains good strength and toughness at cryogenic temperatures. Common applications include tooling for aerospace composites, standards of length, measuring devices, thermostat rods, laser components and tanks and piping for the storage and transportation of liquefied gases.
FORGING: The principal precaution to observe in forging is to heat quickly and avoid soaking in the furnace. Long soaking may result in a checked surface due to absorption of sulfur from the furnace atmosphere and/or oxide penetration. A forging temperature of 2000/2150øF (1100/1180øC) is preferred.
Invar alloy 36 may also be swaged and cold upset.

GRINDING: A silicon carbide wheel is desirable, preferably a soft wheel which will wear without loading. For finish grinding, a satisfactory grade to start with is No. 80 grit.

WELDING: Alloy 36 can be welded by the conventional methods. Caution must be taken so as not to overheat the molten metal. This will avoid spattering of the molten metal and pits in the welded area. When filler rod is required, Invar rod has been used.
BRAZING: Silver and zinc-free alloys have been used for brazing Invar 36. This alloy should be annealed prior to brazing. Joints should be designed to avoid placing material in tension during brazing.

PLATING: Alloy 36 can be chromium, cadmium and nickel plated or zinc coated by the usual methods used for ferrous alloys.
