1) Mild Steel (C-45)
This steel is relatively cheap. The steel is soft and cannot be fully hardened. It is extensively used to manufacture plates like top plate, bottom plate, ejector plate, core and cavity housings, spacers etc. It has high tensile strength. This steel has good shock resisting and machining properties.
2) Case hardening Steel (17MnCr95)
Initially these steels do not have sufficient carbon content essential for heat treatment process. Carbon is induced into the outer layer of the steel to convert into high carbon steels with carbon content ranging from 0.9 to 1.2%. When heat-treated achieve a hardness up to 50 – 55 HRC on the surface and retains a soft tough core. This is used for finger cam, guide pillars, guide bushes, ejector guide pillars and bushes and push back pins, as they require adequate strength as well as wear and resistance properties.
Composition:
Carbon-0.17%, Silicon-0.25%, Manganese- 1.25%, Chromium-1.15%, Sulphur-0.035%
3) Hot Die Steel (T35Cr5MoV1)
This steel has alloying element like carbon, which increases strength, elasticity and hardness. Chromium improves corrosion resistance, toughness and hardenability. Molybdenum improves creep strength and vanadium, which oxidizes and promotes fine-grained structures which is very helpful in manufacturing core and cavity of the mould. This material is hardened up to 48 – 50 HRC. This type of steel is used for core and cavity inserts, core and cavity sub inserts and side core pins.
Composition:
Carbon-0.37%, Silicon-0.25%, Molybdenum-1.2%, Vanadium- 1.0%, Chromium-5.0%
4. Oil Hardened Non Shrinkable Steel (T110W2CR5)
These steels tend to have good hardening properties and have less dimensional changes during heat treatment. They are relatively inexpensive, readily available, have good machinability, good resistance to decarburization and have a high carbon content to provide good wear resistance. The depth of hardness is homogeneous. This material is hardened up to 48 – 50 HRC. This steel is used for guide rails, wear plates, wedges, side core holder, sprue and sprue puller bushes.
Composition:
Carbon-0.95%, Silicon-0.35%, Tungsten-0.5%, Manganese- 1.20%, Chromium-0.5%
