Our comprehensive database includes tool steel brand names – specifications and grades old and new. These magnetic and heat-treatable steels are used in knives, cutting tools, as well as dental and surgical equipment. 5 Classification of tool steels 17 5.1 Water-hardening steels 17 5.2 Low-alloy special purpose steels 17 5.3 Mould steels 18 5.4 Shock-resistant steels 18 5.5 Hot-work steels 18 5.6 Cold-work steels 19 5.7 High-speed steels (HSSs) 20 Appendix 1 - Variation limits in composition of each tool steel group. W.M. Ordinary steel ( P≤0.045% , S≤0.050% ) Tool steels are yet another classification or type of metal you can find on the market. Tool Steel H11 is a chromium-based steel alloy from the “H” family of steels according to the AISI classification system. The classification methods of steel are varied, and the main methods are as follows: Classification by quality. These characteristics have made A-2 a very popular and widely used material. The H Grade Tool Steels were developed for strength and hardness during prolonged exposure to elevated temperatures. Martensitic: Martensitic steels contain 11-17% chromium, less than 0.4% nickel, and up to 1.2% carbon. 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 is an air hardening (cold work) tool steel with wear properties between 0-1 oil hardening and 0-2 air hardening. H11 is one of the most commonly used alloys from this group, thanks to the outstanding impact toughness. A-2 Tool Steel. Several grades have additional resistance to corrosion due to … 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. Some people just use the colours while others will use the various codes associated with each product. 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. Garrison Jr, in Encyclopedia of Materials: Science and Technology, 2001. –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. Classification of … For mass production use Recommended YSS steel. Tool steel is typically used in a heat treated condition which provides increased hardness. Tool steel to standards including BS4659, BS EN ISO 4957, Werkstoff, AISI, DIN 17350, ASTM A681 and EN10027-2 are stocked as well as other designated standards. 1020 AISI/SAE steel numbers are indicated below. All of these tool steels use a substantial amount of carbide forming alloys. Stainless steels are a iron-based alloy containing at between 10.5% to 30% Cr. For example, most commercial steels are classified into one of three groups: plain carbon, low-alloy, and high-alloy. Steel framing classifications mostly come from ASTM. This steel is unique in this respect. Tool steel equivalent chart, compare difference maker and standard. 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. German Specifications Similarly British Standard 4659 is an endorsement of the AISI classification. 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. The selection of a material for a particular application will depend upon design, service conditions, and desired properties. Our tool steel is supplied in accordance with our ISO 9001:2008 registration. In manufacturing, both cold-rolled and hot-rolled steel are used in a variety of alloys. 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. AISI H-10, H-11, H-12, H-13 AISI H-19, H-21 H-13 is the most common hot working tool steel. Tool steels are groups into six types: high speed, hot work, cold work, shock resisting, special purpose and water hardening. Please request with our sales team if placing any orders. Example AISI/SAE No. YSS Cold Work Tool Steels. Its hardness, resistance to abrasion and ability to retain shape at increased temperatures are the key properties of this material. A-2 offers good toughness with medium wear resistance along with relatively easy machining. All our tool steel specifications and grades are available with a cast and analysis certificate, 3.1 mill certificate or a certificate of conformity. High-speed steels are very efficient with heavy cuts and high speeds they are incapable, at slow speeds and lighter cuts, of holding the keen edge necessary for obtaining a very smooth finish on certain articles.
