Product Introduction

X52QS is a high strength steel that belongs to the API 5L standard PSL2 level. "X52" represents its yield strength (≥360Mpa) ; The letter "Q" refers to the heat treatment process of quenching and tempering ; The letter "S" indicates resistance to sulfide stress cracking and suitable for acidic environments.
X52QS seamless steel pipe adopts a low carbon equivalent design, usually Ceq ≤ 0.43, Pcm ≤ 0.25, combined with the addition of microallying elements such as Nb, V, Ti, etc., which not only ensures welding performance but also improve the comprehensive performance of the steel pipe.
After the heat treatment process of quenching and tempering, X52QS seamless steel pipe can maintain high toughness at low temperatures and resist impact and vibration.
