Products Charecteristics
1.2436 Cold Work Forged Alloy Tool Steel Bar is an excellent choice for those who demand high wear resistance and exceptional edge holding ability.
1. A kind of cold work tool steel with excellent wear resistance and edge holding ability
This kind of tool steel has a high surface hardness after heat treatment, which makes it perfect for use in applications where durability and longevity are key factors.
2. High surface hardness after heat treatment.
This steel also possesses good toughness, high compressive strength, and impressive through hardening properties. This means that it can withstand heavy use and maintain its edge even under challenging conditions.
3. Medium toughness, but high compressive strength, and good through hardening properties and dimensional stability
Thanks to its excellent dimensional stability, 1.2436 Cold Work Forged Alloy Tool Steel Bar is a reliable option for use in precision applications where accuracy and consistency are vital.
Heat Treatment
Annealing
800 to 850°C
Slow con trolled cooling in furnace at a rate of 10 to 20°C/hr down to approx. 600°C, further cooling in air.
Hardness after annealing: max. 250 HB
Stress relieving
650 to 700°C
Slow cooling in furnace; intended to relieve stresses set up by extensive machining, or incomplex shapes.
After through heating, hold in neutral atmosphere for 1 to 2 hours.
Hardening
950 to 980°C
Oil,
salt bath (220 to 250°C or 500 to 550°C), air plast, still air. Holding
time after temperature equalization: 15 to 30 minutes. Obtainable
hardness: 64 - 66 HRC.
Special treatment: Hardening 1020°C and tempering at 500°C.
Obtainable hardness approx. 61 HRC (e.g. if followed by nitriding).
Tempering
Slow
heating to tempering temperature immediately after hardening/time in
furnace 1 hour for each 20 mm of workpiece thickness but at least 2
hours/cooling in air. For certain cases we recommend to reduce tempering
temperature and increase holding time.
