Cold Work Tool Steel Suppliers in Mumbai
Cold Work Tool Steel is primarily high carbon steels comprising comparatively low tungsten, chromium, manganese, and molybdenum additives to alloys. These improvements to alloy make it hardenable, making oil tempering with little deformity than with the W sequence. Such are comparatively affordable steels, and their high carbon composition provides sufficient strength to use for short-term implementations.
Over high temperatures these has minimal resistance to softening. Most manufacturers supply compositional steels in this category of steels, formulated to fulfill particular requirements. Unquestionably, this category of steels can be counted as the highest tonnage used during the production of tools, the purpose being that this is the lowest expensive; this is not really possible to match a high level of non-distortion in thermal treatment and short-term implementation. Cold Work Tool Steel are used at processing temperatures of about 200 ° C, and are distinguished from high wear resistance rates.

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. These are relatively cheap steel, high carbon content they will produce sufficient wear resistance, used for short-term operations. 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: W1, W2, W5 tool Steel; O-1, O-2, O6, O7 Oil Steel; A2, A4, A6, A7, A8, A9, A10, A11 Cold work Steel; D2, D3, D4, D5, D7 Steel; etc.

In cutting operations the toughness of AISI A2 steel gives excellent resistance to chipping of the cutting edge. In many cases, tools made of A2 steel have given better tooling economy than high-carbon, high-chromium steels of the D3/ W.-Nr. 2080 type. AISI steel A2 has much better machining and grinding properties.
A-2 is an air hardening (cold-work) tool steel with wear properties between O-1 oil hardening and O-2 air hardening.
This offers good toughness with medium wear resistance along with relatively easy machining. A-2 also has excellent non-deforming properties. These characteristics have made this steel a very popular and widely used material.
A-2 has a machinability rating of 65% of a 1% carbon tool steel and it is sold in the annealed condition. Typical annealed hardness is BHN 197/241 Rc 12/22.
With a maximum working hardness is BHN 698 Rc 62, A-2 is capable of meeting ASTM-A681.
