METHODS OF CHECKING RESISTANCE TO CORROSION OF COPPER BEARING STEEL PLATE FOR GOODS WAGONS AND BASES FOR A SPECIFICATION FOR THIS TYPE OF STEEL
The problem confronting the Committee concerns the definition of a steel quality slightly liable to oxidation, which makes it possible to construct, for the wagon of the future, wagon bodies with the same duration of life as that envisaged for the whole wagon. The Committee was also requested to define a method for checking the resistance to corrosion of a type of steel. After having taken note of the numerous tests carried out by the Specialists, the Committee thinks it impossible to develop an accelerated laboratory method, the results of which would be in accordance with the corrosion in service. Contrary to this, the Committee is of the opinion that some Administrations have acquired such an experience that they can recommend a type of steel having proved its value in current use for twenty-five years. This concerns a semi-stainless copper bearing steel - with a copper content of 0.25 to 0.50% - high mechanical properties - tensile strength 52 kg/sq mm - weldable without special precautions. The Committee is however of the opinion that the Mn - Cr - Cu and P Cu - Cr - Si steels can also offer interesting possibilities, and proposed to envisage the construction of wagons from these types of steel in view of the comparative large scale practical tests.
