为了探讨热处理方法及显微组织的影响,研究了高强度抗硫化氢石油用钢中碳化物组织的效应。使用了一种高强度低合金钢进行了一系列的热处理以改变碳化物的分布及形状,在奥氏体化后用了六种不同的冷却方法,用不同的温度和时间进行了回火。抗硫化氢腐蚀破裂性能的测定使用了恒负荷法及简支梁法。在讨论中从氢的陷阱理论出发着重指出了碳化物球化的有利作用。
In order to investigate the influence of heat treatment and microstructure, the effect of carbides on high strength hydrogen sulfide resistant steel was studied. A series of heat treatments were performed using a high strength, low alloy steel to change the carbide distribution and shape. Six different cooling methods were used after austenitizing and were tempered at different temperatures and times. Determination of resistance to hydrogen sulfide corrosion cracking using constant load method and simply supported beam method. In the discussion, we begin with hydrogen trap theory and point out the beneficial effects of carbide ballization.
