What is Sour Service Steel Pipe

The hardness of the sour service pipe is more strict,because the hardness value has a greater impact on HIC.The research shows that the higher the material strength,the greater the hardness,the stronger the HIC sensitivity in low and medium strength steel.Mechanical properties ofTube and Pipe for Hydraulic Prop Manufacturer Cloud Specifications Standards GB/T17396-2009 Main Materials 20#,45#,27SiMn Sizes O.D.51-406mm Wall thickness 6-70mm Length Any length,or Customized.Applications The seamless steel tube for hydraulic prop is mainly used for hydraulic system,plastic machinery,injection molding machinery,rubber machinery,metal forming machinery,die casting machinery,construction machinery,air The influence of original structure on the microstructure The experimental results show that thus quenched 27SiMn steel by zero time holding quenching obtains a fine lath martensite structure and higher tensile strength and hardness.The mechanical properties of the thus quenched 27SiMn steel are better than that of the thus normalized 27SiMn steel.
