Product Description
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
