ASTM Standard List: Forgings, Welding and Filler Materials and Powder Metallurgy

Sommario:

ASTM specifications represent a consensus among producers, specifiers, fabricators, and users of steel mill products. ASTM’s designation system for metals consists of a letter (A for ferrous materials) followed by an arbitrary sequentially assigned number. These designations often apply to specific products, for example A548 is applicable to cold-heading quality carbon steel wire for tapping or sheet metal screws.

This article contains a list of standards that covers among other things:

  • Carbon Steel Forgings for General Industrial Use
  • Vacuum-Treated Carbon and Alloy Steel Forgings for Turbine Rotors and Shafts
  • Alloy Steel Forgings for High-Strength Pressure Component Application
  • Standard Specification for Sintered Ceramic Ferrite Permanent Magnets
