ISCOR 57 South African steel rail is a type of railway rail that conforms to the specifications set by the South African Bureau of Standards (SABS) and was previously manufactured by ISCOR, a South African state-owned steel company.

The “57” in the name refers to the weight of the rail in kilograms per meter. Thus, the ISCOR 57 rail weighs 57 kilograms per meter. This rail is commonly used in mainline railway networks in South Africa and other countries where it has been exported.

ISCOR 57 South African steel rail typically has a height (also known as the rail head) of around 132-140 millimeters, a base width of approximately 140-150 millimeters, and a web thickness of around 8-10 millimeters. It is made from high-quality carbon steel and may be heat-treated or quenched and tempered to provide the necessary strength and durability for railway operations.

ISCOR 57 South African steel rail is designed to withstand heavy axle loads and high traffic volumes typical of mainline railway networks. It is also suitable for use in curved tracks and can be welded or joined using fishplates to create continuous rail lines.

While ISCOR is no longer in operation, ISCOR 57 South African steel rail remains a widely used standard in South Africa and other countries where it has been adopted. Proper installation, maintenance, and inspection of the ISCOR 57 rail are essential to ensure its continued safe and efficient operation in railway networks.

Why the quality of our steel rail is very good?

1. Because we control the producing process since steel melting.

(1) Rail was produced by very specialized process.
(2) Liquid iron will be desulfurization before steel marking.
(3) Slag stoppers are used in tapping operation to eliminate or minimize the carryover of slag into the steel ladle.
(4) The steel ladle will be stirred by argon in the bottom for liquid steel temperature homogenized, steel composition uniformed and removal of nonmetallic inclusions.
(5) On the top of ladle add insulating slag as precaution after tapping.
(6) Steel temperatures, chemical compositions and deoxidation practices can be controlled more precisely by second refining.
Vacuum degassing is used for removing gases such as hydrogen, oxygen and nitrogen. Improve the purity of steel through removing oxygen and removing nonmetallic inclusions by flotation.
(7) Avoid second oxidation in continuous casting through in-ladle slag carryover predication, protective casting, tundish metallurgy and mould level automatic control.
(8) Improve the surface quality and segregation through control the constant casting speed, in-mould electromagnetic stirring, dynamic control of secondary cooling and soft reduction in final stage.
(9) Rolling by Universal mill and right designing to ensure the better profile and tolerance.
(10) Two times descaling will be used to improve rail surface quality.
(11) The independent drive prebend device is used to prebend the rail reliably and remove the bending rail safely during the cooling process to reduce the residual stress.
(12) All rail shall be straightened and ultrasonically tested by a continuous process to ensure whole of rails length and specified cross sectional area are inspected fully.

2. Arrange quality control plan according to technical specification and contract before production.
3. Inspection and Test Plan shall be arranged as per the technical specification and contract before production.
4. Mill’s Certificate: Products can’t be sold and dispatched from the factory if it is not qualified.
5. Shipment: The rail will be delivered by railway or truck according to different length.
6. Loading and unloading shall use special rail clamp, to avoid the head of rail damage.
7. Loading plan shall be arranged before loading according to different vessel to ensure quality and safety of the goods.
