Cold Work Tool Steel. Cold work tool steel basically is high carbon steel. The alloy contains tungsten, manganese, chromium, and molybdenum relatively low alloy steel. These alloys added to improve hardenability, allowing less distortion than the W series of quenching oil. The first edition of this book appeared in , but it has been for some years out of print. Meanwhile the great stir about steel specifications caused by the war impressed new ideas about steel and its heat treatment on most engineering firms, much to their benefit in all respects, except, perhaps, in relation to case-hardening steels.
When carbon steel is used for punching dies or cold hobbing tools the dimensions of the tool are bound by a ruling section that is determined by the load on the tool. A punch or a die, made from carbon steel, having a diameter of, say, 50 mm, will show rather poor resistance to sinking on account of the shallow depth of hardening. Low carbon case hardening steel is made through one such process through which a metal’s outer crust is made very hard and tamper proof without disturbing its internal compositions. Case hardening of low carbon steel material is quite popular and is widely employed and finds varied applications in .

Case-hardening steel. A tough core and a hard case are the desired attributes of case-hardened steel components. This combination of properties provides wear resistance and fatigue strength at the surface, and impact strength in the core. It is achieved by carburizing the component’s surface, then quenching and tempering the part.

Cold work tool steels are essentially high carbon steels, which contain relatively low alloy additions of tungsten, manganese, chromium and molybdenum. These alloy additions increase hardenability, permitting oil quenching with less distortion than with the W series.

In Introduction to Aerospace Materials, High-strength low-alloy steels. High-strength low-alloy (HSLA) steels contain a small amount of carbon (under %) like mild steels, and also contain small amounts of alloying elements such as copper, nickel, niobium, vanadium, chromium, molybdenum and zirconium.

The low alloy steels include alloys with small additions of chrome and nickel up to the 11/13Cr steels with 4% nickel. The addition of these elements improves the high temperature performance and imparts some corrosion resistance. The addition of chrome and nickel improves the thermal stability of steel and makes these steels popular for applications which suffer wide temperature ranges.

It is a popular case hardening steel grade for general engineering, readily machinable and weldeable in its supply condition.
EN32 is a low tensile steel suited for lightly. The steels best suited for case hardening are the low-carbon and low-alloy series. When high-carbon steels are case-hardened, the hardness penetrates the core and causes brittleness. In case hardening, you change the surface of the metal chemically by introducing a high carbide or nitride content.
The core remains chemically unaffected.

This steel can achieve a high hardness, but it is rather brittle when compared to other tool steels. All W-Grade tool steels must be must be water quenched, which can lead to increased warping and cracking. Typical applications of W-Grade tool steel include Cold Heading,Cutting tools and knives, Embossing, Reamers and Cutlery.
Air Hardening.D2 steel shows little distortion on correct hardening. D2 steel’s high chromium content gives it mild corrosion resisting properties in the hardened condition. Cold-work tool steels include the high-carbon, high-chromium steels or group D steels.
These steels are designated as group D steels and consist of D2, D3, D4, D5, and D7 steels.
