A material guide to the best casting grades

A catalogue that connects industries to South Africa’s best foundry

With Steloy’s global infiltration into many sectors including the petrochemical industry in the recent years, a material catalogue was essential in order to document the range of steel materials that Steloy design and manufactures. The cornerstone of steloy’s material catalogue is Steloy’s timeless ethos of quality, customer service and dedication to being South Africa’s leading steel material manufacturers and foundry experts.

Our material catalogue is a detailed, visual manuscript of Steloy’s steel casting grades, alloys, standards of manufacturing, design and size specifications, codes as well as chemical compositions of the materials we use.
