What is Cold Work Tool Steel? & What is Hot Work Tool Steel? Cold Work Tool Steel Cold work tool steel basically is high carbon steel, the alloy content 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. These are relatively cheap steel, high carbon content they will produce sufficient wear resistance, used for short-term operation. It is used for all types of blanking and forming dies, gauges, fixtures, etc. In ASTM Steel standard Cold Work Tool Steel main include the “W” (Water Hardening), “O”(Oil Hardening), “A” (Medium Alloy Air Hardening), “D” (High Carbon, High Chromium) Tool Steel Series. Typical Steel Grade like: W1, W2, W5 tool Steel; O1, O2, O6, O7 Oil Steel; A2, A4, A6,A7,A8, A9,A10, A11 Cold work Steel; D2,D3, D4,D5,D7 Steel; etc. Hot Work Tool Steel Hot working tool steel to make iron and nonferrous metals as well as hot for...

Many industries place strict requirements on the acceptable level of surface defects and imperfections that may appear on a plastic molded part. Such conditions often apply to critical components for the medical and pharmaceutical industries as well as for the manufacturers of lenses and other optical devices. However, for aesthetic reasons, many other consumer goods have similar restrictions. After all, any defect that appears on the surface of the mold steel is likely to be replicated onto the molded part. Problems associated with the texturing or polishability of a mold cavity can often be traced back to the mold steelmaking process. The material properties that have shown the greatest influence on obtaining a good surface finish are the microcleanliness level, the severity of chemical segregation and the appearance of primary carbides. The mold steel's chemical composition along with the manufacturing techniques used during its production, will determine its ability to p...

There are no shortcuts in producing good tooling. Lack of attention in any of the following areas can result in poor tool quality, poor part quality, low yield or worse – tool failure: Tooling design Material selection Tooling manufacturing process Heat treating and finishing Today, we are going to talk about tooling design. Careful consideration should always be given to the design, material and fabrication of tooling – let’s face it, finished parts are only as good as the tooling used to create them. There are several variables such as heat, pressure and speed that can contribute to excessive tool wear or tool failure. Managing these variables, sourcing the right tool steel and applying good tool design sensibility will help you avoid downtime and extend tool life.  Here are some common problems and solutions to consider when designing and fabricating tooling: At Otai Special Steel we work closely with customers to help them select the right tool steel for the...

Tool steels feature the increased amount of carbon and other alloying elements which give them enhanced physical properties, making them the ideal choice for a variety of applications. Cutting tools, cams, dies, chuck jaws, blocks, gages, and drill bits are just some examples of the many different tool steel applications. Along with many different applications, there are also many different tool steel grades available, including cold-working tool steels that encompass water-hardening tool steels, oil-hardening tool steels, and air-hardening tool steels. There are high-speed tool steels, hot-working tool steels, and shock-resisting tool steels as well. With so many different choices, it is necessary to be able to identify the correct tool steel for the job. Listed in this article are seven things to consider when selecting a tool steel grade. Will the tool steel be subjected to large impacts? Tool steels are generally hard and brittle. When impacts occur on materials like this, it...

What is oil  O1  Steel?  AISI /  ASTM A681  O1  tool steel  is a low alloy cold work tool steel that must be oil-quenched in heat treatment. Tools and dies made from O1 tool steel flat or rounds will have good wearing and abrasive qualities since the tungsten and higher chromium content gives improved wear resistance. ASTM O1 tool steel has deep hardening properties with fine grain structure with unusual toughness. AISI O1 tool steel offers good durability, gives excellent wear resistance and holds a good cutting edge. O1 cold work tool steels also have a good response to heat treatment with small dimensional changes. We are a better choice of O1 oil tool steel materials supplier with reliable quality and sales service. AISI Tool steel O1 is available in standard de-carb free rounds, flats, and squares, as well as the largest size selection in O1 oil steel ground flat stock and drill rod of all the tool steel grades, or as per customized requ...

D2 Tool Steel | 1.2379 | X153CrMo12 | SKD11 We are professional cold works  D2 tool steel  supplier for more than two decades. We supply AISI /  ASTM A681  cold works  D2 tool steels alloy steel materials in reliable quality and for attractive price for sale. We have deep knowledge of D2  tool steel ’s chemical composition and properties. Contact us for any D2 tool steel materials demands. Cold Works D2 tool steel is a high carbon, high chromium tool steel (12% chrome) with extremely high wear resisting properties, heat treatable to 60-62 Rc. D2 steel is very wear resistant but not as tough as lower alloyed steels. D2 tool steel hardens in air with a low order of movement and offers a measure of corrosion resistance when polished. The high percentage of chromium gives it mild corrosion-resisting properties in the hardened condition. The mechanical properties of D2 are very sensitive to heat treatment. D2 steel is available in de-carb free rounds, flats...
