AREAS OF APPLICATION

Areas of application

With a broad range of quality, high-grade, and free-cutting steel we have achieved an outstanding position in the European automotive, engineering and apparatus construction industry. Consistent quality, high delivery performance and efficient logistics are strengths which in turn ensure that our customers have a strong position in their own markets. Our production range includes steels for various purposes:– General structural steel– Heat treatable steel– Case hardening steel– Free-cutting steel– Steel with improved cold forming properties– Micro alloyed steel– Chain steel– Construction / Mining

General structural steelStructural steels usually find their application according to their tensile strength and yield point. Within a given set of tensile properties, we offer different grades according to our customers’ demands on e.g. fracture toughness, weldability, and chemical composition.

Heat treatable steelHeat treatable steels gain their application properties through the process of austenitization, quenching and tempering. In a quenched and tempered condi-tion, heat treatable steels have a minimum range of tensile strength of approx. 470 – 1250 N/mm². Besides a good tensile strength, heat treatable steels also possess a high yield strength and ductility. The properties of the end product should be as homogeneous as possible over the entire cross section. High-grade steels do not only have lower phosphorus and sulfur contents than quality steels, but also more consistent properties, e.g. after heat treatment.

Case hardening steelCase hardening steels are usually steels with low carbon contents, intended for carburisation or carbonitriding, followed by hardening. After hardening, case hardening steels exhibit a surface layer with a high level of hardness and a tough core. The resulting property gradients correspond to the varying stresses and strains imposed on the final parts. The most important steel parameter to be considered is hardenability which is influenced by the chemical composition. In this respect we also distinguish between quality steel and high-grade steel.

13

Free-cutting steelThe demand for automated machining has led to the development of free-cut-ting steels Good machinability and chip breaking properties are usually achieved by alloying with sulfur, manganese and lead. Depending on the material re-quirements steels are classified into soft free cutting steels, free-cutting case hardening steels and free cutting heat treatable steels – the latter with lower phosphorous and sulfur contents.

Steel with improved cold forming propertiesFor this purpose, steels with a low yield stress, low hardening during cold form-ing, and a high formability are required. Besides these characteristics, these steels should be free of internal and external defects, in order to provide an optimal cold heading product. Depending on the steel grade, a special anneal-ing treatment can be applied to achieve lower final tensile properties. Specialty product: Swissbain-7MnB8.

Micro-alloyed steelMicro-alloyed steels exploit the strengthening effect of adding micro-alloying el-ements, such as vanadium, titanium, niobium and aluminium. Ranging from 10-2 to some 10-1 weight %, these elements form precipitates within the steel matrix, which have an influence both on preheating and forming and on the microstruc-tural transformation of the steel.

14

Chain steelBesides strength, brittle fracture resistance and ductility are dominant factors for chain steels. Furthermore, aging and wear resistance, weldability, cold shearing properties and cold formability are very important. The weldability requirement limits the carbon content to about 0.25 %. To enhance the strength with such a low carbon content, manganese, chrome, nickel, and molybdenum are alloyed, resulting in strengths of up to 1500 N/mm² in the chain. Aluminium is alloyed for better aging resistance and grain refinement. Good ductility is achieved by a lowest possible content of accompanying elements, such as phosphorus and sulfur.

Construction / MiningSwiss Steel AG develops and produces special products for construction and mining applications. Our latest developments include the corrosion resistant reinforcing steel Top12, the micro-alloyed reinforcing steel for enhanced static requirements Top700, and the thread bar St900/1100.

The reinforcing steel Top12 is suitable for constructional elements exposed to splash water and stationary water (use of defrosting salt) and for areas suscep-tible to carbonatisation.

Top12 presents a reliable and economic solution for improving the corrosion resistance of reinforced concrete significantly and thus extending its lifetime. Top12 can be projected and handled according to the methods developed for black rebars, without requiring any special treatment on the construction site.

15

Top700 is a new micro-alloyed reinforcing steel exhibiting a yield stress exceed-ing 700 N/mm². The steel therefore meets high static requirements and opens up new options in reinforced concrete construction.

St900/1100 thread bars exhibit a yield stress exceeding 900 N/mm² and feature as-rolled screwable ribs.

All products meet the relevant standards and are being monitored by indepen-dent certifying bodies.

PRODUCTION

Production

Steel production at Swiss Steel is the beginning of a valuable recycling process, and therefore also an important factor of our economy and society from an ecological aspect.

Iron scrap of good quality – mainly of Swiss origin – is melted in our 80-ton electric arc furnace (EAF).

The secondary metallurgical processes are conducted in the ladle furnace (LF):– Alloying and micro-alloying – Temperature adjustment– Stirring

For particulary demanding steel grades, a further secondary refining treatment in the vacuum degassing unit (VD) follows the treatment in the ladle furnace. This treatment reduces the oxygen and nitrogen content of the steel through purging in vacuum.

The continuous casting machine (CCM) then produces the 11 m steel billets of 150 mm square, from which the steel is rolled into bars or wire rod, tested, and finished.

LABORATORY TESTING FACILITIES

Laboratory Testing FacilitiesAccredited testing laboratories for a consistent quality

We carry out chemical, mechanical and metallographic tests in our accredited test laboratories. Swiss Steel AG ensures a continual improvement in the indi-vidual departments due to the continuous feedback of process and test data to the process. Quality Assurance provides proof of the process quality through the accompanying inspections, which are mostly performed in the central test laboratories.

The key areas of our labs are accredited (STS0026) according to ISO/IEC 17025. The current scope of accreditation includes mechanical tests, metallography and spectrometry. The sample preparation department mechanically produces various types of samples in conformity with standards or customer specifica-tions. The test and measuring equipment monitoring department manages all the test and measuring equipment (gauges, micrometers, etc.) at the production site in Emmenbrücke as well as for various external customers.

Our laboratories with their modern facilities are available for analyses and tests commissioned by external customers.
