What tempers of Monel 400 spring wire are available?

Monel 400 spring wire ships in five cold-worked tempers under ASTM B164 Table 2: annealed (soft), quarter hard, half hard, hard and spring. Annealed wire holds about 70 ksi tensile and 35 percent elongation for forming and weld-rod stock. Spring temper runs about 130 to 145 ksi tensile with much lower elongation, used for stressed springs in HF acid valves, brackish water mesh and marine instrument coils. TorqBolt stocks 0.5 mm to 10 mm diameter on standard coil weights.

What is ERNiCu-7 welding wire?

ERNiCu-7 is the AWS A5.14 grade designation for the Monel 400 nickel-copper welding filler wire used for GTAW and GMAW of UNS N04400 plate, pipe, forgings and bolting. Chemistry mirrors ASTM B164: nickel plus cobalt 62 to 69 percent, copper 26 to 32 percent, with controlled titanium and aluminium for weld-pool deoxidation. Common dimensions are 1.6 mm, 2.0 mm, 2.4 mm and 3.2 mm bare rod cut to 914 mm for TIG and 0.9 mm, 1.0 mm, 1.2 mm spool for MIG.

What spool weights are stocked for Monel 400 welding wire?

Monel 400 ERNiCu-7 spool weights: 4.5 kg, 11.3 kg and 22.7 kg metal spools for MIG sub-arc, plus 5 kg cardboard cartons for 914 mm cut TIG rods. Standard packing is moisture-sealed polythene with desiccant, ASTM A604 vacuum-fusion hydrogen control where required for high-restraint root passes. Each spool is heat-numbered and ships with EN 10204 type 3.1 mill certificate; type 3.2 with third-party witness for NORSOK and sour-service repair work.

What is the chemistry of Monel 400 wire per ASTM B164?

ASTM B164 sets UNS N04400 wire chemistry at nickel plus cobalt 63 percent minimum, copper 28 to 34 percent, iron 2.5 percent maximum, manganese 2.0 percent maximum, carbon 0.3 percent maximum, silicon 0.5 percent maximum and sulphur 0.024 percent maximum. ERNiCu-7 welding wire follows the same envelope with tightened titanium and aluminium for weld-pool deoxidation. Free-machining Monel R-405 (N04405) at 0.025 to 0.060 percent sulphur is bar stock only and is not used for wire.
