China SPA-C steel for railway rolling stock price per kg

SPA-C steel for railway rolling stock, S355J2WP plate is a high phosphorus corrosion resistant structural steel, and P is the chemical element phosphorus. S355J2WP steel enhances the atmospheric corrosion resistance applied at ambient temperature. In order to achieve the corrosion resistance, some specific alloy elements, such as P, Cu, Cr, Ni, Mo, etc., are added to form a protective oxide layer on the metal surface under various climatic conditions.

The cold working performance of SPA-C steel for railway rolling stock and so on steel structure engineering steel is good, which can ensure that the steel will not crack or brittle fracture during high-temperature processing, and will not have a great impact on strength, plasticity and toughness due to processing. The durability of SPA-C steel for railway rolling stock and so on steel structure engineering steel is good. Durability refers to the service life of steel structure. The main factor affecting the service life of steel is the poor corrosion resistance of steel, followed by the deterioration of mechanical properties of steel under long-term load, repeated load and dynamic load.

Most common SPA-C steel for railway rolling stock steel plates are rolled by hot rolling or controlled rolling. Compared with the general hot rolling process, the advantages of controlled rolling are: the strength and low temperature toughness of steel plates are greatly improved by controlled rolling to refine grains. In addition, the controlled rolling process can give full play to the role of Microalloying Elements Nb, V and Ti, not only play a role of precipitation strengthening, but also refine the grains, and improve the toughness of the rolled SPA-C steel for railway rolling stock steel plates.

The company will also put Georgetown steelworks on "care and maintenance mode" and temporarily lay off or redeploy about 130 employees working at the steelworks and contractors while some SPA-C steel for railway rolling stock maintenance employees will be on staff during the closure. It is stated that unemployment insurance and state-based unemployment support will be available immediately to workers affected by these changes.
