Nickel-free steel of increased strength and corrosion resistance for freight-car production

Nickel-free 10ΓAΦДΠ1 steel of elevated strength, low-temperature strength, and low-temperature resistance has been developed. On the basis of the new steel, a production technology for rolled sheet and cold-bent profiles (thickness 3.6–5.0 mm) for freight-car production is proposed. In the electrosmelting shop at OAO Magnitogorskii Metallurgicheskii Kombinat (MMK), a batch of the new steel (160 t) has been produced and rolled to 4.5 × 1500 mm sheet in the 2500 mill. Coils of this steel are used to produce bent profiles for freight-car production. The new 10ΓAΦДΠ steel surpasses mass-produced 10XHДΠ 1 steel in terms of its suitability for freight-car components.
