Good Hardenability 1.2344 Tool Steel , Alloy Tool Steel For Die Casting Steel
Introduction:
Grade 1.2344 / H13 is the pressure resistant hot work die steel. After the electroslag remelting, the steel has the characteristic of good hardenability, excellent mechanical and polishing properties, high toughness and plasticity, good high and low temperature wear resistance, and high temperature fatigue and heat resistance.

Features:
Grade 1.2344 / H13 steel is one of the most widely used and representative hot work mold steel.
Its main features are:
(1) High hardenability and high toughness;
(2) Excellent thermal cracking ability, which can be water-cooled
in the workplace;
(3) Tt has moderate wear resistance and can be used to improve its
surface hardness with carburizing or nitriding technology, but it
is slightly reduced to reduce thermal cracking resistance.
(4) Because of its low carbon content, the secondary hardening
capacity is poor in tempering;
(5) Has the ability to resist softening under high temperature, but
using a temperature >540 ℃ (1000 ℉) hardness of rapid decline
(that is, the ability of working temperature is 540 ℃).
(6) Small deformation of heat treatment;
(7) Medium and high cutting processing;
(8) Medium resistance to decarbonization.
