TEMPER TYPES
Alloy QQ-A-250/8, 5052 is supplied in a wide range of tempers:
  • O - Soft
  • H34 - Stabilised - A low temperature thermal treatment or heat introduced during manufacture which stabilises the mechanical properties and relieves residual internal stress, plus usually improves ductility
  • H112 - Alloys that have some tempering from shaping but do not have special control over the amount of work-hardening or thermal treatment.
  • H24 - Work hardened by rolling then annealed to half hard
  • H26 - Work hardened by rolling then annealed to three-quarter hard
  • H32 - Work hardened by rolling then stabilised by low-temperature heat treatment to quarter hard
  • T36 - Solution heat treated then cold worked by a reduction of 6%
