4140 quenched and tempered steel tube
4140 quenched and tempered steel tube is used extensively in applications for automotive industry, Hydraulic, Mining and oil and gas drilling industry. 4140 Q&T tubes include 4140 Q&T seamless steel pipes and 4140 Q&T drilling hollow bars. 4140 steel pipe has higher strength than 4130 pipe.
Heat Treated Steel Tube we produce are Round Steel Tubing such as annealed tubing, normalized tubing and quenched & tempered steel tubing.
4140 Q&T steel tube we supply includes following advantages:
Consistent mechanical properties
Even thickness on the whole bars
Deep mechanical properties
Even hardness on the whole bars/Tougher and Increased strength
No brittle, UT testing/Precision size tolerance/Good straightness
Good Roughness/Professional technical service/Competitive price/Fast delivery
