奥氏体钢在冷变形为40～60%,其强度极限几乎增大一倍,即120～140公斤/毫米~2,而屈服极限增加三倍多(由22～25增加到100～105公斤/毫米~2)。因此,金属对轧管机轧辊的压力增加35～45%,而每小时产量比轧制碳素钢管和低合金钢管平均降低了36%。苏联南方钢管厂运用了乌克兰钢管研究所(yкpHити)研究人员与工厂专家共同 Austenitic steels are 40 to 60% cold-deformed, with their ultimate strength almost doubling, ie 120 to 140 kg / mm2, and the yield limit more than tripling (from 22 to 25 to 100 to 105 kg / Mm ~ 2). As a result, the metal pressure on the roll mills increased by 35-45%, while the hourly yield was reduced by an average of 36% over the rolled carbon and low-alloy steel tubes.
