SCM440 quenched and tempered steel tube
SCM440 quenched and tempered steel tube is used extensively in applications for automotive industry, Hydraulic, Mining and oil and gas drilling industry. scm440 Q&T tubes include scm440 Q&T seamless steel pipes and scm440 Q&T drilling hollow bars. scm440 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.
SCM440 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
