In addition to standard, structural (carbon) steels, Euro-metals also offer the so-called special steels. Special steels differ in their characteristics from ordinary structural steels. In principle, these are iron alloys whose properties can be changed in three ways:
A change in processing A change in chemical composition A change in the production process
Special steels are generally alloy steels that contain several different chemical elements.
From our offer of special steels we single out:
- Improving steels can be carbon (non-alloy) and low-alloy, which by the process of heat treatment (hardening and tempering) achieve the appropriate strength properties, but also the required toughness. These steels are most often used in the machine industry (production of axles and shafts), automotive industry, special-purpose industry, shipbuilding, metal processing (production of screws, wedges, levers, etc.).
- Improved steels - The main characteristic of improved steels is that they are hardened in water from the forming temperature, and additionally tempered at a temperature of 680-710 ° C, while achieving the appropriate strength properties, but also the required toughness. They have the same, or similar application as hardening steels.
- Cementing steels are a group of steels, which after processing, by separating the particles, carburize the outer (surface) layer. After carburization of the outer layer, hardening is carried out in order to achieve high resistance of the outer layer to wear, and increased toughness of the non-carbonaceous core. Cementation steels generally contain 0.1-0.2% C before carburization, and the outer layer contains 0.8-0.9% C after carburization. The carburization process is called cementation. These steels are used in the machine industry (production of gears and other transmissions), special-purpose industry (production of weapons), shipbuilding, metal processing, etc.
- Steels for vending machines are intended for the production of parts on high-performance automatic machines. Their main characteristic is better machinability, compared to other steels. The machinability of these steels is achieved by means of a modified chemical composition which promotes the formation of inclusions, which enable the formation of brittle and short sawdust.
- Tool steels are stainless carbon or alloy steels with a carbon content of 0.6% to 2.06% or alloyed (mainly with Cr, W, V, Mo, Co), and are used for tool making. The basic properties that tool steels must possess are wear resistance and high impact resistance. Production (economic) requirements and properties according to tool steels are: possibility of tool processing by particle separation, high hardenability, high hardenability, slight change of dimensions during work, possibility of processing, corrosion resistance, possibility of polishing, economy, etc.
We offer our customers the service of cutting these steels to measure on 3 automatic CNC saws.
