Production of corrosion-resistant S420K2W and S460K2W structural steel

Abstract

The alloying of steel resistant to atmospheric corrosion is discussed. The differences and similarities of the Russian GOST, European EN, and United States ASTM standards regarding the chemical composition of such steel are analyzed. The prospects for the production of corrosion-resistant high-strength steel sheet exceeding the requirements in the EN 10025-5 standard are considered. In trials, the possibility of producing steel sheet with elevated low-temperature impact strength is demonstrated. Production technology for high-strength steel resistant to atmospheric corrosion is developed.
