88.9mm 30CrMo Seamless Steel Tube for Drilling & Industrial Apps

2026-02-06

Product Introduction

Our 88.9mm 30CrMo seamless steel tube is engineered for high-stress environments such as geological drilling and precision automotive parts. Manufactured by Jiangsu Hongbao Group (Pipe) Co., Ltd (since 1958), this pipe leverages the high fatigue strength and toughness of 30CrMo (AISI 4130) alloy steel. Utilizing advanced RX Gas Protected Bright Annealing, we ensure a scale-free surface and superior straightness.
