摘　　要：文章对包钢生产的G105、S135钢级石油钻杆管体用钢的淬透性进行了试验研究,结果表明:两个钢种具有良好的淬透性,在880~900℃的淬火温度下,G105钢获得最小50%、90%、95%马氏体洛氏硬度值的淬透层深度分别为15 mm、9 mm、7 mm;S135钢获得最小50%、90%、95%马氏体洛氏硬度值的淬透层深度分别为35 mm、18 mm、15 mm。The experimental study on the hardenability of G105 and S135 grade petroleum drill pipe body steel produced by Baotou Steel is introduced in this paper.The results showed that the two steel grades were with good hardenability.With the quenching temperature of 880~900℃,the hardening layer depths of the minimum 50%,90%and 95%martensite rockwell hardness numbers were 15 mm,9 mm and 7 mm for G105 steel;the hardening layer depths of the minimum 50%,90%and 95%martensite rockwell hardness numbers were 35 mm,18 mm and 15 mm for S135 steel.
