High quality steel that is used for cutting, shearing, forming and stamping of plastics and metals known as tool Steel. Typically this steel is used to manufacture the production of industrial cutting tools and tooling components. Electric melt furnaces are used for producing stringent quality standards Tool steels.
Tool steels are used for larger elements or parts that need to have minimal distortion during hardening. Using oil quenching and air hardening helps in reducing distortion. Advanced tool steels require high-pressure vacuum processing for maximum results.
Alloying components are widely-used within these metals along with water-hardening grades. These types of alloys require a less substantial quenching process to improve the hardenability of steels.
Low-alloy tool steels include H10-13, A2-6, A8-10, and A11O.
High-alloy tool steels include H14-43, D2-7, and A7.
These tool steels are usually used to make knife blades. The basic types of the tool steel are:
- Plastic mold
- Shock resisting
- Low Alloy Special Purpose
A—Types tool steels:
A—Types A2 to A10 cover a wide range of alloy contents and carbon that have high hardenability. This usually hardened in air. A8 and A9 are the low carbon Types that have less wear resistance. This offers greater toughness for Guillotine Blades than others. A—Type also gives exceptional wear resistance with high carbon and vanadium. Tool steels usually combine with the carbide forming elements with from 0.6% to 2.6% give hardness and wear resistance.
W—Types tool steels:
The W-type tool steels are increased toughness by alloying with manganese, silicon and molybdenum. Up to 0.20% of vanadium is used to retain fine grain sizes during heat treating.
Tool steels are manufactured under properly planned process with carbon content between 0.7% and 1.5% managed temperatures to generate the required quality. The manganese material is often kept low to reduce the possibility of cracking during water quenching. On the other hand, proper heat treating of these steels is essential for adequate functionality and there are many companies who offer tooling blanks designed for oil quenching.
Alloy content is used for welding tool steels that is differ from the low carbon machinery tool steels. To maximum hardness in and near the welded area, the welding temperatures will high. This type of localized hardening can cause severe cracking that’s why it is necessary to precautions being taken to prevent cracking.
