摘要: 研究了在線?；に噷?duì)J55鋼管的組織和性能的影響。研究結(jié)果表明,采用在線?；に嚿a(chǎn)J55鋼管,會(huì)在少量降低鋼管強(qiáng)度值的情況下,大幅度提高鋼管的沖擊韌性。Abstract: The effect of on-line normalization treatment on structure and properties of J55 steel tube was analyzed.The result shows that on-line normalization treatment of the J55 steel tube may slightly reduce strength of the tube, whereas impact toughness of the tube can be significantly enhanced.
