After annealing there will be about 0.20% carbon present as free graphite. Ordinary steel ( P≤0.045% , S≤0.050% ) Tool steels are available in a wide range of grades, based on their composition, the temperature range in which they were forged or rolled, and the type of hardening they have undergone. For example, most commercial steels are classified into one of three groups: plain carbon, low-alloy, and high-alloy. According to the use, the classification of steel can be divided into: Structural steel; Tool steel; Die steel; Spring steel; Bearing steel; Abrasion resistant steel (Wear-resistant steel) Valve steel; Cold heading steel; Free cutting steel; Bridge steel; Marine steel; Boiler steel; Pressure vessel steel; Electrical steel, etc. Classification of … Tool steel is typically used in a heat treated condition which provides increased hardness. A-2 Tool Steel. SLD, SLD-MAGIC, ARK1 DAC, DM SLD, SLD-MAGIC SLD, YXM1 SLD, SLD-MAGIC, ARK1 SLD, SLD-MAGIC, ARK1, ACD8 DM, ACD8 SLD, SLD-MAGIC, ARK1 DM, ACD8 DAC, DM, ACD8 SGT, ACD37, YCS3. Steel framing classifications mostly come from ASTM. Example AISI/SAE No. A2 Tool Steel is a versatile, air-hardening tool steel that is characterized by good toughness and excellent dimensional stability in heat treatment.A2 is intermediate in wear resistance between O1 oil-hardening tool steel and D2 high-carbon, high-chromium tool steel. Rod and Plate Tool Steels. A-2 is an air hardening (cold work) tool steel with wear properties between 0-1 oil hardening and 0-2 air hardening. The code starts with the letter A, followed by a number ranging anywhere from 1 to 1000. Table 1: Cold work tool steel types, according to the US UNS, AISI and SAE classification. If alloying elements is less than 8 %, they are called low alloy steels and if alloying elements is more than 8 %, they are called high alloy steels. German Specifications 1020 As a result, tool steels are suited for use in the shaping of other materials. Similarly British Standard 4659 is an endorsement of the AISI classification. Grades of Hot Working Tool Steel. Tool steels are covered in Australian Standard AS1239 and with some minor modifications in grouping it is an endorsement of the American AISI tool steel classification. This is the most common group of metals used in engineering today. Tool steels are yet another classification or type of metal you can find on the market. An alloy is defined as a separate element or compound added to the base metal, like nickel or chromium. FERROUS MATERIAL - STEELS . The H Grade Tool Steels were developed for strength and hardness during prolonged exposure to elevated temperatures. Tool steels are groups into six types: high speed, hot work, cold work, shock resisting, special purpose and water hardening. –Low Carbon (<0.25 wt% C) –Medium Carbon (0.25 to 0.60 wt% C) –High Carbon (0.6 to 1.4 wt% C) • Steels - alloys of iron-carbon. W.M. Applications in cold work dies. Tool steels As per name tool steels are used for manufacturing different tools. M2: DIN 1.3343 AISI M2: 0.90: 4.00: 1.90: 6.40 W: Well known standrad high speed steel with high wear resistance. A-2 offers good toughness with medium wear resistance along with relatively easy machining. Tool steel equivalent chart, compare difference maker and standard. Stainless steels are a iron-based alloy containing at between 10.5% to 30% Cr. Several grades have additional resistance to corrosion due to … Table of Steel Equivalent Grades (EN, SAE/AISI, UNS, DIN, BS, UNI, JIS) The table below compares steel equivalent grades of materials from various international specifications. These tool steels, which include hot or cold finished bar, plate, sheet, strip, rod, wire, or forgings, are normally fabricated into tools, dies, or fixtures. - May contain other alloying elements. H11 is one of the most commonly used alloys from this group, thanks to the outstanding impact toughness. To help cut through the confusion, our handy colour chart gives you quick and easy way to identify grades by colour or code. AISI - American Iron and Steel Institute; SAE - Society of Automotive Engineers; Alloy steels and carbon steels can be designated with specific grades by a four-digit AISE/SAE numerical index system. Please request with our sales team if placing any orders. Tool steels, along with stainless steels, are a sub-group of alloy steels. CLASSIFICATION. These characteristics have made A-2 a very popular and widely used material. Garrison Jr, in Encyclopedia of Materials: Science and Technology, 2001. All our tool steel specifications and grades are available with a cast and analysis certificate, 3.1 mill certificate or a certificate of conformity. GENERAL CHARACTERISTICS: CORODUR WZ 55 is a flux cored wire which deposits an air hardening and wear resistant alloy and can be applied to reclaim hot-forging dies and to overlay the edges and flat areas of low alloyed high density steel tools. Note that materials compared are the nearest available grade and may have slight variations in actual chemistry. Steel classification is important in understanding what types are used in certain applications and which are used for others. Some people just use the colours while others will use the various codes associated with each product. YSS Cold Work Tool Steels. For manufacturing different tools different properties are required such as hardness, resistance to abrasion, wear and deformation and ability to hold a cutting edge at high temperatures. In manufacturing, both cold-rolled and hot-rolled steel are used in a variety of alloys. Engineering steel grades can be confusing! Our comprehensive database includes tool steel brand names – specifications and grades old and new. It is easy to derive from the name that tool steels are part of the steels group. A-2 also has excellent non-deforming properties. A2 Tool Steel. Quality Assured Supply. Our tool steel is supplied in accordance with our ISO 9001:2008 registration. CLASSIFICATION OF STEELS 5. Tool steel refers to a variety of carbon steel and alloy steel that are particularly well-suited to be made into tools.Their suitability comes from their distinctive hardness, resistance to abrasion and deformation, and their ability to hold a cutting edge at elevated temperatures.
