Nickel Alloy Wires Inconel 625 Air Pollution Control UNS NO6625 Waste Treatment

Welding wires are slim metallic wires that are usually coiled up in spools. These spools are loaded on a wire feeder and the welding wire is continuously fed through a welding gun into the molten weld pool. As a result, arc welding processes that use a welding wire tend to offer higher deposition rates and faster travel speeds, as compared to TIG and Stick welding where the welder must manually feed the filler metal into the weld puddle.

Nickel Alloy 625 (UNS NO6625) is a material withexcellent resistance to pitting, crevice, and corrosioncracking. This alloy is highly resistant in a wide range oforganic and mineral acids, and it exhibits good hightemperature strength. Excellent mechanical properties at both extremely lowand extremely high temperatures. Outstanding resistance to pitting, crevice corrosion, and intercrysta ine corrosion. Almost complete freedom from chloride induced stress corrosion cracking. High resistance to oxidation at elevated temperaturesup to 1050°C. Good resistance to acids, such as nitric, phosphoricsulfuric, and hydrochloric, as wel as to alkalis makespossible the construction of thin structura parts ofhigh heat transfer.

Applications

• Components where exposure to sea water and higrmechanical stresses are required.
• Oil and gas production where hydrogen sulfide anoelementary sulfur exist at temperature in excess of150°C.
• Components exposed to flue gas or in flue gasdesufurization pants.
• Flare stacks on offshore oil platforms.
• Hydrocarbon processing from tar-sand and oil-shale
• Recovery projects.

Fabrication Data:

Alloy 625 can be easily welded and processed by standard shop fabrication practices, however because the high strength of the alloy, it resists deformation at hotworking temperatures.

• Hot Forming. The hot-working temperature range for Alloy 625 is 1650–2150°F (900–1177°C). Heavy working needs to occur as close to 2150°F (1177°C) as possible, while lighter working can take place down to 1700°F (927°C). Hot-working should occur in uniform reductions to prevent duplex grain structure
• Cold Forming. Alloy 625 can be cold-formed by the standard shop fabrication practices. The alloy should be in the annealed condition. Work hardening rates are higher than the austenitic stainless steels.
• Welding. Alloy 625 can be readily welded by most standard processes including GTAW (TIG), PLASMA, GMAW (MIG/MAG), SAW and SMAW (MMA). A post weld heat treatment is not necessary. Brushing with a stainless steel wire brush after welding will remove the heat tint and produce a surface area that does not require additional pickling.
• Machining. Alloy 625 should preferably be machined in the annealed condition. Since Alloy 625 is prone to workhardening, only low cutting speeds should be used and the cutting tool should be engaged at all times. Adequate cut depth is necessary to assure avoiding contact with the previously formed work-hardened zone.
