Railroad fastener Carbon Steel Rail Cast Iron Shoulders Weld On Shoulders
Specifications:
The iron shoulder is cast in the concrete ties for fixation of elastic rail clips. Our rail cast iron shoulders include M.C.I. shoulder manufactured from pearlitic malleable iron and S.G.C.I. shoulder manufactured from spheroid graphite iron. We offer two types of iron shoulders. One is Single Stem Iron Shoulder used in pre-stressed concrete ties and the other is Twin Stem Iron Shoulder used in Bi-Block or Twin Block concrete ties.
Casting shoulders are pressed in concrete sleeper and assembled with E clip in order to fasten the rail. The material we use is cast iron and the mechanical property and chemical composition of the rail cast iron shoulder are shown below:
Material | Tensile Strength(Mpa) | Yield Strength(Mpa) | Elongation(%) |
QT400-15(GGG40) | 400 | 250 | 15 |
QT450-10(GGG45) | 450 | 310 | 10 |
QT500-7 (GGG50) | 500 | 320 | 7 |
| C | Si | Mn | P | S |
QT400-15 | 3.6-.36 | 3.0-3.2 | 0.5 | 0.07 | 0.02 |
Qt450-10 | 3.4-3.9 | 3.7-3.0 | 0.5 | 0.07 | 0.03 |
QT500-7 | 3.4-3.8 | 2.5-2.9 | 0.6 | 0.08 | 0.025 |
Weld-on shoulder is used for the typical position of rail. This rail cast iron shoulder is welded on flat steel plate instead of the standard tie plate and is produced according to AREA standard. Designed for use with E style elastic rail clips, the weld on shoulder fastening allows customers to fabricate rail retaining units on both steel sleepers and steel base plates.
The rail cast iron shoulders can also be welded on to longer length steel sleeper sections or bearers for use in the fabrication of switch and crossing layouts where vertical rail geometry is employed. The railway shoulder's ability to be welded in the specific position as dictated by the layout design makes it particularly useful and cost effective in this role.
