Technical Menu Posted on July 1st, 2015 by vapro

The ASTM F467 specification covers the chemical, mechanical, dimensional, and workmanship and finish requirements, and the corresponding test methods for commercial wrought nonferrous nuts in a variety of alloys in common use that are intended for general service applications. When tested, the nuts shall meet required values for hardness, proof stress, and tensile stress areas.

Typical Applications

  • Pulp and Paper Industry
  • Salt Water Equipment
  • Acid Processing Plants
  • Oil Refinery
  • Gas Scrubbing
