The special characteristic of stainless steels is that they have a resistance to corrosion that is significantly higher with respect to other steels; some of them also have an excellent resistance to high temperatures.

These characteristics of stainless steels are obtained thanks to the addition of chromium and other alloy elements, and allow use even in particularly aggressive environments such as chemical plants, marine environments and offshore platforms. These qualities of resistance to assaults makes them perfect materials to be used also in architecture to increase the durability of the objects created.

Some of these steels, thanks to a chemical composition that is particularly rich in nickel and chromium, are called “refractory steels” and can withstand high temperatures with a limited loss of the mechanical characteristics.

Stainless steels can be provided in their natural rolling state or annealed, normalized, quenched and tempered, or heat-treated. Bars, coils, and wires are available with a wide variety of packaging.

Rodinox^® is a complete range of reinforcing products for concrete, in bars and coils, available in all the most important stainless steel types and it is the solution when the environment is aggressive.

In these situations the usual carbon steel reinforcing bars may corrode, with destructive results on the structure. Actually, stainless steel reinforcing bars are resistant to corrosion, a real problem for carbon steel bars, that can be accelerated by chemical processes such as carbonation due to atmospheric attacks or infiltration of chlorides into the concrete.

The use of Rodinox^® enhance durability on the concret structures, making possible to calculate the duration of the reinforcement for all the life of the artifact: moreover, designing with Rodinox^® does not require special modification of the criteria comparing to the usual carbon rebar. Rodinox^® can be processed in the same way as carbon steel bars, with the only caution of avoid contamination of stainless surface by using clean machines.

The Roda Custom Line^® is born, it contains different types of products, each with its own characteristics and certificates, identifiable each one with its own brand name.

The aim is to make products of high quality and performance available on the market, not only on stainless steels, but also for the alloy and free-cutting steels, offering to our customers a wide range of possibilities that can be customized « ad hoc » for every single customer according to his needs.

With the aim of proposing a range of tailor - made steel solutions, Rodacciai presents on the market Roda RTM^®.

Steel bars ready to be used and machined, to provide innovations and solutions with the maximum yield and more & more oriented to the needs of its customers. The new concept of Roda RTM^® « ready to machine » fully describes the improvement strategy adopted by Rodacciai, based on experience and continuous study.

The cold-drawn wire used for cold-heading included in the Rodacciai production range are divided into 3 main categories:

• Low carbon steels
• Boron-alloyed steels
• Alloyed steels, without Boron added

The standard reference for the supply of intended products to cold deformation is EN 10263:2017.

supplies the steel grades mentioned in the various parts of the Norm (ref. parts 1 - 4), in different supply conditions and according to the requirements provided for the different features of the product: mechanical properties, decarburization, surface finishing, surface quality, etc. Rodacciai can also evaluate specific requirements from customers that go beyond the requisites of EN 10263 : 2017, studying a customized product.

Rodacciai’s production range is completed by different types of special steels intended for multiple uses, which can satisfy the particular and niche needs of many users.

The steels reported in this section are those most commonly produced by Rodacciai, but several other types, not included in this site, are produced upon request.

The heat treatments available for this type of steel - to be checked on a case-by-case basis according to the different qualities - are: rolled natural, workable annealed, isothermal annealed, globular annealed, normalized, and quenched and tempered.

The steels for high-speed machining, commonly called free-cutting steels, have been specially designed to be machined by chip removal with high productivity.

Free-cutting steels - which are commonly used in many mass production fields such as the automobile industry and household appliances - contain sulfur and some other elements, including tellurium, bismuth and lead, which promote machinability.

In particular, the sulfur ensures the fragmentation of the chip, lead reduces the friction between the tool and piece, extending the life of the tools, and the tellurium and bismuth further accentuate these characteristics.

Free-cutting steels are usually supplied in bars or rolls without heat treatment; some of these can however be tempered, normalized or annealed before finishing.

Wires and bars of stainless steel of various types are used as filler materials in electrode, MIG, TIG, and submerged arc welding: according to requirements, austenitic, martensitic, ferritic or austenitic-ferritic, also called duplex steels are used for welding.

The use of selected wire rods with controlled impurities guarantees optimal welding from both the mechanical strength and resistance to corrosion points of view. Furthermore, the chemical composition of the proposed welding steels is defined in such a way as to be compatible with all of the international standards, including the European and American ones.

Thanks to the quality of its welding steels, Rodacciai has supplied all of the major producers of electrodes in Europe, the United States, and throughout the world over the years, passing even the most demanding tests: the product certifications issued by TÜV (Germany), Controlas (Holland), ABS (U.S.A.) and CWB (Canada) bear witness to this fact, without counting the approval by the major international car manufacturers.

A recent study conducted by the Earth Energy Center at Columbia University shows the enormous potential of modern technologies that convert waste to energy, improve energy security, reduce greenhouse gas emissions and waste to energy, improve energy security, reduce greenhouse gas emissions, and reduce pollution and landfill waste generation. To this end, they must act on the control of corrosion caused by combustion technologies used in this sector.

With a view to sustainability, Rodacciai, with its R&D and in-house lab, has developed a steel solution focused on the waste-to-energy industry,proposing a consumable alloy for high temperature welding, RODA ALLOY 625 (ERNiCrMo - 3).
With its extremely high corrosion resistance and customizable characteristics, this product is the perfect solution for critical environments.
