Abstract

Настоящее изобретение относится к составам стали, обеспечивающим улучшенные свойства в коррозионной среде. Варианты воплощения изобретения также относятся к поверхностной защите стали путем уменьшения проникновения водорода. Кроме того, обеспечивается хороший контроль процесса в отношении рабочего времени термической обработки и устойчивости к поверхностному окислению при температуре прокатки.
