Longer service life.


At S+C, we offer you decades of experience in the field of high-quality stainless steel products for usage in strip coating lines. We are continuously working to expand our range of in-house developed materials to widen our product portfolio for you in a practical way.

Surface coating plays a particularly important role in the automotive industry. Thin steel strip is coated with zinc or aluminum/silicon in specialized strip coating lines.

Two main processes are used in continuous strip coating:

• Coating in a molten zinc or aluminum/silicon dip bath
• Coating by using the the electro galvanizing process.

For the rolls used in both processes, S+C has appropriate materials in its portfolio to meet the requirements. Our specialists will be at hand to advise you in detail.

Dip coating.

High temperature corrosion and extreme stress.

Various materials made of Centralloy® centrifugally cast alloys are available for the manufacture of sink and stabilization rolls, some of which are subjected to massive high-temperature corrosion, or for guide and furnace rolls, which are also subjected to extreme stress.

Galvanic strip galvanizing.

High current load and the high aggressive environment of the electrolyte.

Similarly, the conductor rolls used in electrolytic strip galvanizing lines represent a product developed at S+C to a high level of technical maturity. A conductor roll of this type consists, e.g. of a cylindrical mantle made of a centrifugal casting with two lateral journals made of forged material. The purpose of these journals is both: to support the roll and to take up the current and transmit it to the roll via the collector seats, which can also be provided with a copper buildup weld for better conductivity. Both, the current load and the aggressiveness of the electrolyte frequently cause problems at the journals and roller mantle, which S+C solves individually from case to case, thanks to a wide range of available materials.

Required material properties of current roller mantles:

• Best corrosion resistance
• High homogeneity and density of the material structure

Special Cr / Ni / Mo alloyed materials are available for current roller mantles, such as:

• Märker® G4446, W. No. 1. 4446
• Märker® Alloy G45Mo
• Märker® Alloy 59 (̴W. No. 2.4605)
• Euzonit® G60 (W. No. 2.4697)

*The corrosion resistance of G4446 can be further optimized by adjusting the chemical analysis, within its specified limits. (With ferrite content or ferrite-free)

Heat-resistant nickel/aluminum alloys made by S+C

Together with S+C and our patented heat resistant nickel/aluminum alloys, Centralloy® HTE and Centralloy® 60 HT R, you will take your next step forward towards "Green Manufacturing". The proprietary high-performance material Centralloy® 60 HT R, with which application temperatures of up to 1,250 °C are possible, convinces with its exceptional properties compared to conventional materials.

This optimum material is the industry's most temperature-resistant metallic material for furnace rollers. It is particularly creep resistant and retains its shape even at highest temperatures. Customers who previously used water-cooled furnace rollers in their furnaces switched over to "dry" furnace rollers made of Centralloy® 60 HT R after getting detailed advice of S+C.

35% lower energy costs.
Up to $2.3 million savings per year*

Heat-resistant alloys made by S+C.

The optimization of heat-resistant components for a longer service life and better sustainability is now one of the main topics in the equipping of new and existing furnaces. Important aspects in our consulting are operating temperatures, furnace atmospheres, heating, heating curves, product quality, service life expectancy, material selection, etc.

The optimum price-performance ratio is achieved above all by solutions tailored to the individual application.

In the field of heat resistant alloys S+C supplies the following materials:

  • Nickel/chromium alloys
  • Nickel-chromium-tungsten alloys
  • Microalloyed nickel-chromium-tungsten alloys
  • Nickel-chromium-tungsten-cobalt alloys

Heat-resistant stainless steel castings made by S+C.

Whether corrosion resistant, heat resistant or wear resistant, our experts will always find the right solution to ensure that your products perform best. In addition, S+C is certified according to ISO 50001:2018 for energy management systems. This means that energy-saving potentials are identified and leveraged in the manufacturing plant, all in the spirit for a more sustainable production, which includes also recycling.

Customers can offer S+C used stainless steel components so that they can be directly returned to the material cycle or can be professionally recycled.

In the area of heat-resistant stainless steels, S+C supplies the following materials:

  • Ferritic-austenitic cast steel (duplex)
  • Austenitic cast steel (chromium/nickel steels)
  • Microalloyed austenitic cast steel

Economic added value

Example calculation:
furnace rollers in a heat equlization furnace.

A customer who had previously used water-cooled furnace rollers in his furnaces switched to "dry" furnace rollers made of Centralloy® 60 HT R ,after detailed advice from S+C. The higher initial cost compared to conventional water-cooled rollers paid off in lower operating costs and other benefits: By switching to dry furnace rollers made of Centralloy® 60 HT R (360 mm or 425 mm), energy consumption and thus energy costs were reduced by up to 35% annually.

Based on our customer's entire furnace (capacity 4 million tons/year) and taking the longer service life of our furnace rollers into account (50 to 125%), this results in savings of between USD 1.8 and 2.5 million per year.


The lower energy consumption and the lower raw material requirements for the production of the furnace rollers also have another advantage: both protect the environment, which is of increasing importance for companies that are operating sustainably.

Furnace rollers made of Centralloy® 60 HT R in the trial phase at our customer
SMST Deutschland GmbH.

Specialty: The high-temperature range

Challange: Particular challenging are the different temperatures, in a range from 560 - 1,230°C ,in the furnace of our customer SMST Deutschland GmbH.

Solution: In 2006 we started the joint trial phase with the use of our dry furnace rollers. The furnace rollers made of the high-performance material Centralloy® 60 HT R were in use for up to nine years and impressed with their particularly long service life and good dimensional stability. Based on the positive results during the joint trial phase, SMST Deutschland GmbH decided to use additional furnace rollers from S+C since 2012, namely in the high-temperature range up to 1,230 °C. To date, the high-performance material Centralloy® 60 HT R has proven to be particularly suitable for the extreme requirements of our customer's furnaces.
