Special product
Saarstahl Rail produce other types of rail more "special".
Examples of special products :
Sogenox rails
In order to limit electrical contact defects on the track due to rusty rails and thus increase safety, Saarstahl Rail has developed special rails with a stainless steel coating on the running surface: The Sogenox. This special rail can be rolled for all types of profiles (vignole and tongue rails) in standard and non-standard grades. It offers better advantages than reloaded rails (excellent straightness, better profiles, less costly, no delamination, ...)
Bainitic Rails
The B360 rails approved by the SNCF the on the points and counterpoints for movable point crossings of the SNCF high-speed network (new and maintenance) allow to reach lifetimes up to 300 MGT without contact fatigue defects and without grinding.
B320 rails have achieved cumulative tonnages of over 1000 MGT in the Channel Tunnel. The grade is currently performing well at various sites where it is regularly monitored (Switzerland, Germany, France). The bainitic grade B320 has the right balance between wear speed and the appearance of contact fatigue defects. The particular microstructure of the bainitic grade delays the initiation of fatigue cracks and slows their propagation, while the natural wear of the rail helps to eliminate incipient cracks.
Anti-corrosion rails
Corrosion remains a major problem for railway infrastructure, especially in certain specific operating areas (level crossings, tunnels, coastal tracks). Saarstahl Rail offers a wide range of anti-corrosion treatment solutions :
- Hot galvanisation of rails
- Paints (Polyurethane, epoxy)
- Metallization
Metallization provides cathodic protection for the rails, enabling them to withstand severe corrosion environments. These are high performance sacrificial coatings that can be applied to products up to 108m in length.
Hot galvanisation of rails
Galvanised rails are now used to solve very severe corrosion problems, especially in level crossings where they are now installed since 2018 in the most sensitive areas of the SNCF network. Galvanised rails can be offered in lengths of up to 15 m.
Paints (Polyurethane, epoxy)
Paints act as a barrier to limit corrosion in areas subject to moderate corrosion.
The definition of the paints is adaptable to the customers' specifications.
Wear-resistant grooved rails that can be repaired by welding
These are rails that offer the best compromise between wear resistance and fully weld-able for easy restoration by weld deposition of the profile of the worn surfaces (gauge corner and upper surface of the rail head).
The grades offered by Saarstahl Rail are Vanadium-enriched ferrito-perlitic grades. These are:
• The R200V Grade
This is a predominantly ferritic grade with a wear rate identical to that of the R200 grade. It is the most easily rechargeable grade. The use of these rails makes it possible to significantly reduce the costs and risks associated with track reloading.
• The R220V Grade
A grade with a balanced ferrito-pearlitic structure, it has a wear rate between that of R200 and R260. This grade thus makes it possible to combat wear and to significantly reduce the costs and risks associated with track reloading.
• The R260V grade
This is a predominantly pearlitic grade with good wear resistance (comparable to that of R260). It thus contributes to increasing the life of the rail. The track coating of this grade is very robust.
• The R320V Grade
This is a grade with a pearlitic structure that has excellent wear resistance which greatly increases the life of the rail.
