Alloy Steel Fasteners

Corrosion resistance-
• Great level of resistance to carburization and oxidation
• Offer hardness to scale creation up to 2000 degree F
• The functional content of nickel (34 to 37 degree) offers good resistance to embrittlement and chloride stress oxidation crevice
• Resistance from repeating quenching to thermal shock
• Capacity to manage thermal cycling
Alloy steel fasteners are available in many forms such as washers, threaded rods, studs, screws, bolts.

About grade alloy 20-
Alloy 20 grade provides a combination of copper, molybdenum, chromium, and nickel, which offers excellent oxidation resistance. These fasteners are suitable for average range oxidation usage. Alloy grade 20 contains a nickel alloy that is precisely developed to resist the tough environment like warm sulfuric acid. These are another Grade using which alloy steel fasteners are made: B 6, B 7/ B 7M, B 16, 2, 2HM, 2H, GR 6, B 7, B 7M.

Alloy Steel Fasteners Applications-
The performance of these alloy fasteners in high-temperature, high-pressure make them suitable for applications in process industries, such as chemicals and petroleum where they are broadly used in flanges, pressure vessels, fittings, and valves.

Documents and test certificates-
The documentation of Cr-Mo Fasteners include Fumigation certification, heat treatment chart, QAP, packaging list, raw material test report, material traceability report, lab test report, and certificate of origin are the documents offered. The MTC as per EN 10204/3.1B, raw material certificate, radiography test report and the third-party test report is provided to the buyers.
