AISI D6 / DIN 1.2436 Cool Work Tool Steel Bar / Rod Dia 20-1000mm
INTRODUCTION
DIN 1.2436 is a kind of cold work tool steel with excellent wear resistance and edge holding ability. High surface hardness after heat treatment. Medium toughness, but high compressive strength, and good through hardening properties and dimensional stability.
APPLICATIONS
Tool steel round bar DIN 1.2436 is for making cutting and drawing tools for high wear resistance, rolls with high dimensional stability, deep drawing tools, tools of wire, bar and tube production, cold shear blades for thin sheets.

PROCESSING
Heat Treatment
Annealing
-800-850℃
-Slow controlled cooling in furnace at a rate of 10-20℃/hr down to approx.600℃, further cooling in air.
-Hardness after annealing: max. 250 HB
Stress relieving
-650 to 700℃
-Slow cooling in furnace; intended to relieve stresses set up by extensive machining, or in-complex shapes.
-After through heating, hold in neutral atmosphere for 1 to 2 hours.
Hardening
-950 to 980℃
-Oil, salt bath (220 to 250℃ or 500 to 550℃), air plast, still air.
-Holding time after temperature equalization: 15 to 30 minutes.
-Obtainable hardness: 64 -66 HRC. Approx. 61 HRC if followed by nit-riding.
-Special treatment: Hardening 1020℃ and tempering at 500℃.
Tempering
-Slow heating to tempering temperature immediately after hardening/time in furnace 1 hour for each 20 mm of work piece thickness but at least 2 hours/cooling in air.
-For average hardness figures to be obtained please refer to the tempering chart.
-For certain cases we recommend to reduce tempering temperature and increase holding time.
