Alloy steel

Alloy steel is the steel alloyed which has high or improved mechanical properties because of the presence of other elements. The other elements are present in amounts between 1 and 50% by weight. Alloy steels are defined in two groups :-

• Low alloy steels
• High alloy steels.

Low alloy steels are the steels having an alloy contents between 1 to 4%, Whereas on the other hand, High alloy steel are the steels having the alloy content between 4 to 50%. However, Generally alloy steels are defined as low alloy steel.
The basic properties of the alloy steels are:-

• Greater strength,
• Hardness,
• Hot hardness,
• Wear resistance,
• Harden ability or toughness compared to carbon steel

However, In order to achieve such properties, some heat treatment is required.
Some common alloying elements are :-

• Molybdenum
• Manganese
• Nickel
• Chromium
• Vanadium
• Silicon
• Boron

P20 steel is defined as a chrome-moly steel, with having a carbon content of approximately 0.35 to 0.40. With the time, many new variations of basic p20 steel having different chemical composition have been introduced in the marketplace. Each modification has an effect on the various processes used in the fabrication of a mold.
P20 Steel Description:
P20 steel is normally pre-hardened to 29 t0 33 HRC. It has good mirror polish-ability and has less texture making finishing easier. It distribute uniform hardness level even across large blocks. Its Excellent weld-ability with grate toughness and nitriding properties makes it a primary choice for plastic mould maker.

Die steel is the steel for hot work tool steel, The steel having chromium, tungsten in its composition. This hot die steel is best used for:-

• Die casting dies
• Extrusion dies
• Hot forging dies
• Hot gripper & heading dies
• Hot work punches
• Hot shear knives

Stavax ESR Steel is a high-quality electro-slag remelted (ESR) stainless steel. The stavax esr steel is well designed for plastic moulds, which requires following basic properties:-

• good corrosion resistance,
• excellent wear resistance,
• and high degree of polish ability.

More important point is this Stavax ESR Steel provides high internal cleanliness and homogeneity.

C45 carbon steel is a low alloy steel. At common strength level, it has enough toughness, This C45 carbon steel refers to a variety of carbon content. It is good for making tools and also for plastic mould. This c45 carbon steel is prepared through special technique.
