SLD-i Advanced Cold Work Tool Steel

SLD-i

Advanced Cold Work Tool Steel


Another exclusive Hitachi metal, SLD-i is an advanced cold work tool steel improving upon AISI D2 steel. Through extensive research and development, Hitachi’s expert metallurgist team brings a superior product to the tool steel array.

Product Summary

SLD-i’s unique composition features small, dense, homogenous carbide distribution, which provide it with the following unique features:

  • Small and isotropic heat treatment deformation
  • Good galling and wear resistance characteristics
  • Higher hardness ratings than that of D2/1.2379

In addition, SLD-i offers minimal dimensional change under heat, as well as shorter lead times and improved production times over standard D2 steel. When the project calls for only the best in cold work tool steel, look no further than SLD-i.

DAC-Magic

DAC-Magic

Advanced Die Casting


This die steel is used in manufacturing highly precise castings in large volumes quickly.
It combines the ability to withstand high temperatures during heating and quenching in the heat treatment cycle with toughness, and minimal cracking in cooling channels contributes to improvements that mean longer-lasting dies.

Features

  • High strength at elevated temperature and excellent heat crack resistance
  • High toughness prevents gross crack of die
  • Improved stress corrosion cracking resistance reduces crack problem from cooling channel
  • Better machinability than conventional SKD61 improved steel (high toughness type) possible to reduce manufacturing time and total cost

Heat Crack Resistance

Compared with conventional steels, DAC-MAGIC contributes to longer die life due to better heat crack resistance.

Tool Steel

Tool steels are varieties of steel, that because of their hardness, grindability, ability to hold an edge, and wear resistance, are excellent for tool making. These tool steels are often used in applications such as stamping dies, metal cutting tools, shear blades, punches, etc.

There are six general categories of tool steel:

  • Water hardening – also referred to as W-type steel because they are water quenched.
  • Cold-work – further divided into these groups:
    • Oil hardening – also referred to as O-type steel because they are oil quenched.
    • Medium alloy air hardening – also referred to as A-type steel because they are air hardened.
    • High carbon-chromium – also referred to as D-type steel, typically containing 12% chromium and more than 1.5% carbon.
  • Shock resisting – also referred to as S-type steel because of their ability to withstand shock.
  • High speed – also referred to as T-type and M-type steels,  including CPM powder metal, are used in high-speed applications.
  • Hot-working  – also referred to as H-type steel because they are able to resist softening and heat checking at high heat for extended periods of time.
  • Special purpose – include these and others:
    • Plastic mold steels – also referred to as P-type steel
    • Low alloy special purpose – also referred to as L-type steel
