aisi 4130 chromely tubing
aisi 4130 / sae 4130 quenched and tempered steel tube is used extensively in applications for automotive industry, Hydraulic, Mining and oil and gas drilling industry. aisi 4130 / sae 4130 Q&T tubes include aisi 4130 / sae 4130 Q&T seamless steel pipes and aisi 4130 / sae 4130 Q&T drilling hollow bars. After quenching and tempering, 4130 pipe can get higher strength for final usage.
Heat Treated Steel Tube we produce are Round Steel Tubing such as annealed tubing, normalized tubing and quenched & tempered steel tubing.
4130 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
