One of the most important category of bolting alloys exhibit high durability and resisting corrosion and erosion caused to drastic year round weather changes and thus promoting longer product life cycle and reducing the cost. Atmospheric conditions corrodes the surface and forms an adherent protective rust or patina, that inhibits further atmospheric corrosion. Weathering steel is well used in manufacturing fasteners that supports bridges, industrial roofing, open framed buildings and other structural and architectural constructions.

Weathering Steel Fastener Specifications
- ASTM A242/A242MThis specification covers high-strength low-alloy structural steel shapes, plates, and bars for welded, riveted, or bolted construction with atmospheric corrosion resistance intended primarily for use as structural members.
- ASTM A588/A588MThis specification covers high-strength low-alloy structural steel shapes, plates, and bars for welded, riveted, or bolted construction with atmospheric corrosion resistance but intended primarily for use in welded bridges and buildings.
- ASTM A606/A606MThis specification covers standards for high-strength, low-alloy, hot-rolled and cold-rolled steel sheets and strips cut in lengths or coils for structural and miscellaneous purposes. The material shall come in Types 2 and 4 steels having enhanced atmospheric corrosion resistance.
- ASTM A709/A709MThis specification covers carbon and high-strength low alloy steel structural shapes, plates and bars, and quenched and tempered alloy steel for structural plates intended for use in bridges. Atmospheric corrosion resistance shall also be determined.
- ASTM A847/A847MThis specification covers standard requirements for cold-formed welded and seamless high-strength, low-alloy round, square, rectangular, or special shaped structural tubing for welded, riveted, or bolted construction of bridges and buildings and for general structural purposes where high strength and enhanced atmospheric corrosion resistance are required.
- ASTM A852/A852MThis specification covers quenched and tempered high-strength low-alloy structural steel plates for welded, riveted, or bolted construction. The atmospheric corrosion resistance of this steel in most environments is substantially better than that of carbon structural steels with or without copper addition.
- ASTM A871/A871MThis specification covers high-strength low-alloy structural steel plate used for tubular structures and poles. This steel has atmospheric corrosion resistance so it can be used bare or unpainted for many applications.
Other Reference Specifications
- ASTM A6/A6MThis specification deals with the general requirements that apply to rolled structural steel bars, plates, shapes, and sheet piling.
- ASTM A370This specification covers procedures and definitions for the mechanical testing of steels, stainless steels, and related alloys
- ASTM A673/A673MThis specification covers the procedure for Charpy V-notch testing of structural steel and contains two frequencies of testing.
- ASTM G101This guide presents two methods for estimating the atmospheric corrosion resistance of low-alloy weathering steels, such as those described in Specifications A242/A242M, A588/A588M, A606 Type 4, A709/A709M grades 50W, HPS 70W, and 100W, A852/A852M, and A871/A871M.
