Изобретение относитс к области создани жаростойких сталей и предназначено дл изготовлени изделий, работающих длительное врем при высоких темлературах до 650°С в контакте с продуктами сгорани высокосернистых мазутов;The invention relates to the field of creating heat-resistant steels and is intended for the manufacture of products operating for a long time at high temperatures of up to 650 ° C in contact with the combustion products of high-sulfur fuel oils;
Известна жаростойка сталь, содержаща углерод, кремний, марганец, хром, алюминий, цирконий, азот и железо.Heat-resistant steel containing carbon, silicon, manganese, chromium, aluminum, zirconium, nitrogen and iron is known.
С целью повышени технологичности предложенна сталь дополнительно содержит кальций при следующем соотношении компонентов , вес.%:In order to improve processability, the proposed steel additionally contains calcium in the following ratio of components, wt.%:
