Nickel Alloy Steel Bolting June 2000

BROAD PARTICIPATION from the steel, nonferrous metals, and alloys fields is needed to produce a specification of basic requirements for alloy precipitation-hardening bolting materials for high temperature service. Steel industry consultants, academicians, bolting materials producers, and users are invited to develop this specification with a task group of ASTM Bolting Section A01.22.01. The group functions in Subcommittee A01.22 on Steel Forgings and Wrought Fittings for Piping Applications and Bolting Materials for Piping and Special Purpose Applications, part of Committee A01 on Steel, Stainless Steel and Related Alloys.

The activity recently received approval from both A01 and Committee B02 on Nonferrous Metals and Alloys. The proposed specification will be based on Committee B02’s Standard Specification B 637 for Precipitation-Hardening Nickel Alloy Bars, Forgings, and Forging Stock for High-Temperature Service. Fastener-specific criteria will be added.

For further information, contact Section A01.22.02 Chairman Lester Burgess, U.S. Bolt Manufacturing, 12895 S. Main St., Houston, TX 77035 (713/726-1000).

Committee A01 meets Nov. 13-16 in Orlando, Fla. For meeting or membership information, contact Committee A01 manager George Luciw, ASTM (610/832-9710). //
