Stainless steel with ideal magnetic properties


Ugitech expands its portfolio

From liquid metal to tested magnetic rod – Ugitech offers an extensive portfolio of stainless steel with ferromagnetic properties. The Swiss Steel Group company has many years of experience in steel production. Customers receive technical support when selecting materials and benefit from solutions that are individually adapted to the respective requirements. The ferritic and martensitic steels impress thanks to top quality and are continuously tested and proven in numerous certified processes.

Ferromagnetic material is often used in the automotive industry, food industry, electricity sector and industrial processes. For example, the role and functioning of solenoid valves, electric pumps, injectors, disconnectors and electromagnets is based on the magnetisability of the steel used. Depending on the application, materials with high corrosion resistance, great mechanical strength or special magnetic properties are required. In addition, other characteristics such as electrical resistance and machinability as well as weldability are important. In order to be able to offer the perfect stainless steel for a wide range of applications, Ugitech has a large steel range. The customer selects the appropriate material from a variety of products with different chemical compositions and different mechanical and magnetic properties. During this process, the specialist manufacturer offers comprehensive advice and uses its years of experience as well as the latest findings from its own research and development centre to provide technical support. 

A wide range of ferritic and martensitic steels

The ferritic materials developed by Ugitech are particularly suitable for electromagnetic actuators thanks to their soft magnetic properties. They differ in terms of their relative magnetic permeability and resistance to pitting corrosion. For example, the sulphurised steel grade UGI 4106 when non-magnetically annealed or IMRE when magnetically annealed exhibits a better corrosion resistance than the classical grade UGI 4105SI used in many applications. Staying in the family of sulphurised steel grades, when magnetic permeability of the reference grade UGI 4105SI is not high enough, Ugitech recommend to use UGIPERM 12FM which allows to enhance relative magnetic permeability for electromagnetic actuators from µr = 1600 to µr = 1800.

Ugitech’s steel grades are ideally suited for use in both sensors and actuators. The ferromagnetic material is available as a round bar, hexagonal steel or profile bar with different dimensions and can be processed by Ugitech if required, for example, ground or drawn.

Top-quality materials – guaranteed certified

Ugitech continuously tests the steel grades using standardised measuring instruments in certified procedures. For example, type A direct current permeameters and coercimeters are used to determine the magnetic behaviour of materials under static and dynamic conditions. The tests also include chemical analyses, metallographic examinations and non-destructive material tests. In this way, the specialist for long products made of stainless steel ensures that it fulfils customer requirements in the optimum way for the long term.

Article by Ugitech

Ugitech is one of the world's leading manufacturers of stainless steel long products.

The company's main products are: billets, bars, wire rod and drawn wire, which the company manufactures in its own steelworks and transforms in its hot rolling mills, finishing shops and wire drawing plants.

Stainless steels are characterized by their high mechanical properties and their corrosion resistance. They are used for the manufacture of a multitude of parts, including valves, turbine components, welding rods, automotive injectors or surgical devices.

With more than 110 years of experience in steel manufacturing and continuous research in the field of metallurgy, the company guarantees optimal steel solutions for the demanding applications of its customers from the automotive, construction, process industry as well as the aerospace, nuclear and medical sectors.


UGIMA® - Creating productivity

Easy Machining

The UGIMA® and UGIMA® HM or XL grades can:

  • increase productivity by between 10% and 50%, depending on the grades*
  • double tool life**
  • provide performance levels that can be repeated from one batch to another

All this, by improving chip breakability and the surface finish of the parts.
With UGIMA® grades, this real achievement (performance level) is accessible to all types of machines and tools.

*with a constant tool lifetime – **after optimising cutting conditions

More than 30 UGIMA® grades are available

Technical support

Experts available throughout the world to help you. They can provide you with information and help you optimise your back-office or in-situ cutting conditions.

The UGIMA® solution and Ugitech’s technical support are unsurpassed!


UGIGRIP®… Choosing durability

Sustainable management of our heritage is an ethical and ecological necessity. It is also an economic imperative, which requires achieving the lowest possible life-cycle cost over the structure's service life.

In the most exposed parts of the structure, stainless steel reinforcing bars are the most efficient solution to ensure the durability of concrete. Stainless steel rebars are used for repairs and for new works, partially or completely replacing carbon steels, both in precast products and for the execution of cast-in-situ structures.

The UGIGRIP® range provides a guarantee of:

In addition to their excellent corrosion resistance which ensures a long service life for structures over several decades, the UGIGRIP® range provides a guarantee of:

  • Higher mechanical properties than with conventional steel, which allows the use of smaller cross sections or a reduction in reinforcement (meaning weight and labour savings);
  • Mechanical properties – yield strength and elongation – meeting the requirements of Eurocode 8, class M for earthquake-resistant construction;
  • A selection of non-magnetic stainless steels for buildings where this property is required: hospitals, banks, airports, meteorological stations, etc.
  • Mechanical properties at high temperature – tensile and creep – exceeding those of conventional steels, giving improved fire resistance;
  • A very low thermal conductivity which gives this product exceptional properties for treating thermal bridges.

UGIGRIP® products can be delivered in various forms:

  • Indented wire coils
  • Indented bars
  • Wire ties dia. 0.8 mm or 1.2 mm
