As a result of the trial phase in partnership with S+C, the dry furnace rollers made of Centralloy® 60 HT R have proven particular successful.
Centrifugally cast furnace/construction tubes for economic advantages.
Higher working temperature. Longer service life.
At S+C, we base our activities on decades of experience in the production of tubes for the usage in industrial furnaces. We are continuously working to expand our wide range of in-house developed materials and to broaden our product portfolio to meet industrial requiremets.
Industrial furnaces exist for diverse applications and many industries. In the heat treatment of steels and other metals, construction tubes like supports and charging fixtures are often used in the furnaces, which have to withstand very high temperatures, weights and possibly temperature changes over a long period of time.
For this purpose,S+C supplies centrifugally cast tubes made of heat-resistant cast steel and nickel-based alloys, either in the as-cast condition, pre-turned or finish-machined, or as welded constructions, also in combination with steel parts from other manufacturing processes.
We will be pleased to advise you on the most suitable material.

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*
* Model calculation. Furnace-specific benefits must be considered specifically.
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
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.
