Product Description

25CrMo4 quenched and tempered steel tube

 

Heat Treated Steel Tube we produce are Round Steel Tubing such as annealed tubing, normalized tubing and quenched & tempered steel tubing.


25CrMo4 quenched and tempered steel tube is used extensively in applications for automotive industry, Hydraulic, Mining and oil and gas drilling industry. 25CrMo4 Q&T tubes include 25CrMo4 Q&T seamless steel pipes and 25CrMo4 Q&T drilling hollow bars. 25CrMo4 steel pipe's strength is little lower than 4130 pipe.

 

25CrMo4 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
