DIN 1652-4: 1990 / Bright steel made from steel for quenching and tempering; technical delivery conditions

Heat Treatments

  • End quench test: Quench from 850°C Carburizing: 880 to 980°C; NOTE: If steels are direct hardened, in general, a carburizing temperature of 950°C is not exceeded. For special procedures, for example under vacuum, higher temperatures (for example 1020 to 1050°C) are not unusual. Core hardening: 860 to 900°C; Case hardening: 780 to 820°C; Tempering: 150 to 200°C (as a guide, for 1 hour minimum).
  • Hardness, Brinell, HB 30 < 217; Hot working 1050-850; Normalizing 860-900; Operation of hardening - Oil 850-880; Soft annealing 680-720; Temper 540-680; Operation of hardening - Water 840-870
