Steel is an iron alloy containing between 0.02% and 2.06% carbon (C), free from all kinds of undesirable elements and compounds. It has become the most important material of modern life and industry thanks to its hardenability, ductility and shapeability. Steel with desired qualities can be obtained through different productions, alloying or appropriate heat treatment. In 2013, 1.6 billion tons of steel in approximately 2500 types were produced in the world. There are a total of about 2,000 steel types, with 1,500 types of steel classified as special steels in the European steel register, published in cooperation with the European Steel Registry Office. In addition to these standardized steels, there are also many non-standard steel types. The production of such special steels, which contain certain properties, requires extensive knowledge, which is mostly available in industrialized countries. The greatest potential for steel as a material to be open to continuous development lies in this type of steel. We provide services in these steel groups: Tool Steels, Stainless Steels, Nitriding Steels, Tempered and Carbon Steels. Cold Work Tool Steels, Hot Work Tool Steels, Plastic Mold Steels, High Speed Steels, Powder Metallurgy Steels, Nitriding Steels are produced by our partner, Germany's 300-year-old steel producer Dörrenberg Edelsthal. We offer New Generation Tool Steels, developed with unlimited knowledge and high technology, to the use of Turkish industry.
WHAT ARE THE TYPES OF STEEL?
Steel is divided into different classes according to its chemical composition, working conditions, production process, use and chemical or mechanical properties.
Steels are divided into 2 categories according to their chemical composition:
a) Carbon steels
b) Alloy steels
Carbon Steels
As the most important alloying element in steel production, carbon not only affects weldability and formability, but also closely affects mechanical characteristics such as tensile strength, yield strength, fracture extension, hardness and wear resistance. Rebars, profiles, wires and sheets are mostly referred to as St. Sulfur is lower in those with medium and high carbon. It has features such as easy processing, clean surface, availability in certain sizes, suitability for heat treatment, bending and deep drawing.
Alloyed Steels
They are high quality machine manufacturing and tool steels. Alloy steel is a non-separable compound consisting of two or more elements, at least one of which is metal. For example, iron is an element. When combined with carbon, it forms steel. Steel is an alloy. Alloying elements are elements added to metals to give them some properties. Carbon is an alloying element in steel. Changing the proportions changes the properties of the steel. Some elements should be as little as possible in the mixture. Elements such as oxygen, hydrogen and nitrogen create voids and defects in the steel. Other elements such as phosphorus, sulfur, selenium and arsenic reduce the good properties of steel. During the manufacture of steel, attempts are made to remove such elements.
WHAT IS TOOL STEEL?
Tool steels are high-quality steels used in shaping raw materials such as metal, plastic, ceramics and wood as all kinds of molds or tools. It accounts for 8% of the world's total steel production. It is divided into four main classes. The names of these classes also determine their usage areas.
Cold Work Steels
They are generally used in the production of molds and tools that operate at temperatures up to 250 °C and below. Good wear resistance, appropriate toughness, machinability and dimensional stability are among the features expected from these steels. They are alloyed to provide good wear resistance and toughness depending on the area of use. In addition, machinability and dimensional stability during heat treatment are among the characteristic features of these steels. However, resistance to high temperatures is not a sought-after feature. Cold work steels are divided into three types. These; are tough cold steels (Example: 1.2767-VNC, WP7V), hard cold steels (Example: 1.2842, 1.2510) and carbide-rich cold work steels (Example: 1.2379, 1.2436).
Hot Work Steels
It is generally used at temperatures of 250 °C and above, and in molds and tools that are constantly exposed to temperatures between 30-600 °C. Hot work steels are expected to maintain their mechanical properties at high temperatures and have high wear resistance and thermal conductivity. These properties are achieved by the appropriate addition of chromium, molybdenum, tungsten, vanadium, nickel and cobalt elements to hot work steels. The importance of choosing a suitable steel, appropriate machining, appropriate heat treatment and proper use is most evident in hot work steels. If one or more of these four stages are missing, the mold may crack, break, premature wear, etc. Such negativities are inevitable.
In recent years, the production of hot work steels produced by Electro Slag Remelting (ESR), has been increasing. Sulfur, which settles on grain boundaries at high temperatures and causes grain brittleness, is in minimal amounts in these steels. Warping during heat treatment is minimal. 1.2343 and 1.2344 steels are produced in large diameters by the EFS + ESR method.
Extra Fine Structure (EFS) are hot work steels with a very fine structure. The structure of these steels has been made extremely thin by applying some extra processes during production. In this way, mechanical properties are ensured to be the same at every point (isotropy). The advantages of these steels are;
The alloying elements are very well distributed.
Sulfur, which causes grain brittleness at high temperatures, is at a minimum level.
An extremely uniform structure prevails in the annealed structure.
It is the best pre-treatment as it has a shorter diffusion distance before the subsequent hardening process.
Examples of the most commonly used hot work steels are 1.2343, 1.2344, 1.2365, 1.2367, WP7 V, 1.2713 and 1.2714.
Plastic Mold Steels
These are steels that are exposed to abrasion, pressure and corrosion depending on the type of plastic raw materials used. Plastic mold steels are exposed to abrasion, pressure and corrosion depending on the type of plastic raw material used. Therefore, a wide variety of plastic mold steels have been developed. The most commonly used plastic mold steels include 1.1730, 1.2312, 1.2738, 1.2311, 1.2344, 1.2379, 1.2767, 1.2842, 1. 2083, 1. 2316, 1. 4112, 1.8519, 1.8550.
High Speed Steels
These are steels that can maintain their hardness at high temperatures caused by friction in tools that cut, twist and plaster at high speeds.
Apart from steels, there is a group of non-ferrous metal alloys used in tool and mold making, which are called "hard copper alloys". These copper alloys are alternatives or complements to steels in some applications. These alloys are divided into beryllium, zirconium, nickel alloys and bronzes.
WHERE IS STEEL USED?
Steel is a valuable alloy used in a wide range of industries, from the defense industry to white goods, from the food industry to the automotive industry. Since it does not cause any chemical changes in foods, it is frequently and safely used in the food industry.
Steel is used to produce products such as small household appliances, white goods, industrial kitchens, the automotive industry, leather, chemical and oil industry, aviation industry, nuclear engineering, communication equipment, heat-resistant parts and containers.
