O1 Tool Steel is a very good cold work steel and also makes very good knives and forks. 0000075905 00000 n Using motor oil is another way that you can harden mild steel. Angle Light a propane blow torch to use as a heat source. It is a superior quality steel which has excellent wear and abrasion resistance properties. Grade Summary: O1 Tool Steel is a general purpose oil-hardening tool and die steel. The main alloying element found in group W steels is carbon. Surface hardening, treatment of steel by heat or mechanical means to increase the hardness of the outer surface while the core remains relatively soft. The group … Cold-work tool steels are high carbon steels that are further classified into three subgroups such as oil-hardening steels, high-carbon, high-chromium steels, and air-hardening steels. Therefore, if you want to put a hard layer on steel, you need to make sure the carbon is fused at a molecular level on the top centimeter of the steel. striking punches are other examples of carbon tool steels that require What is oil hardening steel ? Figure 1. Tool Steel Grades Water Hardening (W-Grades) This is basically a high carbon steel. 0000006010 00000 n This group of tool steel is the most commonly used tool steel because of its low cost compared to others. We achieve increased hardness (and therefore the strength) of steels using the vacuum hardening and tempering processes. If your tool was hard after quenching, in all probability, the hardening part of the process was correct. equivalent chart 0000008637 00000 n somewhat larger amounts of alloying elements. angles the cooling effect must be very intensive at these areas. in Figure 1 shows how the hardening temperature affects the depth If the tool Hardening and Tempering of Tool Steels Abstract: The cost of the steel and its heat treatment amounts generally to less than a quarter of the total cost of the whole tool. Carbon Tool steel is designed to be resistant to wear and impact, with a hardness high enough to cut another steel. In order to put a hard layer on the steel, carbon must be fused at the molecular level into the top centimeter or so of the steel. steel starts to be coarse-grained when the hardening temperature The useful alloy content of most tool steels exists as carbide particles within the annealed steel. Hardening processes of tool steels in a vacuum furnace are highly dependent on alloy. To increase the wear resistance and hardenability of the W steels, a small amount of chromium can be added. Most widely used in the M series. 0000006839 00000 n For sections heavier than 20 mm Hardening steel with motor oil is a way of performing what is called the case hardening of steel. hardening comparison table, Carbide the depth of hardening, i.e. The steel has a high chromium content (11 to 13 percent) and relatively high amounts of molybdenum (.7 to 1.2 percent), vanadium (1.1 percent), cobalt (1 percent) and other elements.

The very considerable The exceptions to this are the prehardened steels such as P-20, Brake Die, Holder Block and Maxel Tooling Plate which are furnished at 28/32 HRC and used at that hardness. Other considerations during heat treatment include the type of furnace, quenching medium and work piece transfer facilities.

Almost all are hardened and tempered. tools, hardenability may be a crucial factor and under such circumstances It can be hardened to about 57-61 HRC. Analysis: C CO CR MN MO NI P S SI V W; 0.70 – 1.50: 0.15 Max. The combination of a hard surface and a soft interior is greatly valued in modern engineering because it can withstand very high stress and fatigue, a property that is required in such items as gears and anti-friction bearings. 0000082441 00000 n D2 tool steel is an air-hardening, cold work, high carbon, high chrome tool steel with exceptionally high wear resistance properties. Carbon Water-hardening tool steels are also known as group W steels. All W-Grade tool steels must be must be water quenched, which can lead to increased warping and cracking. The purpose of hardening is to enable the tool to resist wear and make it hard enough to cut other materials; tempering is carried out after hardening to reduce the brittleness which results from hardening the steel. temperatures. 0000007845 00000 n The prefix "A" in the name designates it as an air-hardening steel. alloy Depth of hardening for carbon steel, 25 mm in diameter, the distance from the surface to the This group of tool steel is the most commonly used tool steel because of its low cost compared to others. Hardening steels involves the basic process of heating the steel to organize the crystalline structure in a uniform way and then rapidly cooling it by quenching it to lock the molecular make-up of the steel. 0000075423 00000 n All come with a traceable lot number and test report.
