摘要
采用42MnMo7、41MnV5钢锻坯,经热轧穿孔、冷拔加工,试制出STM-R80地质钻探管。该地质管经检验和使用,质量符合要求。介绍了钢的化学成分、试制的主要工艺过程及其参数。
STM-R80 geological tubes can be developed with the billets forged from 42MnMo7 and 41MnV5 steels through hot piercing and cold drawing. The tubes can meet the quality requirements by inspection and application. Their chemical, compositions, developing process and process parameters are introduced.
