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

Application of 4140 chrome bar

Image
4140 is a 1% Chromium - Molybdenum high tensile steel supplied in the hardened and tempered, cold drawn or turned, precision ground, polished, chrome plated and final polished condition, with a typical base metal tensile strength of 850 - 1000 Mpa, plus a typical hard chrome plated surface hardness of HV 1000 - 1150.Characterised by an extremely smooth surface finish with excellent wear and corrosion resistance, coupled with a base material giving high strength and good impact properties, plus good machinability. 4140 hard chrome plated bar is used extensively by the hydraulic and pneumatic industries, and is employed by other industry sectors for a wide range of applications requiring higher strength. Typical applications are: Agricultural Equipment, Hydraulic Cylinders , Hoists, Jacks and other Lifting equipment, Machine Tools, Mining and Earth Moving Equipment, Pumps, Valves, Waste Disposal Transport and Equipment etc. Anbao Hydraulic is a professional manufacturer in

Cold working method for cold drawn seamless steel pipe

Cold working method for cold drawn seamless steel pipe The cold working method of   seamless steel pipe ,  includes cold rolling and cold drawing method to produce a complete set of equipment for the pipe. It is a unit for deep processing of hot rolled pipe or welded pipe. The production characteristics of cold-rolled precision steel pipe processing pipe unit is that the pipe material is usually subjected to multiple cold deformations and work hardening from the input to the finished product. Therefore, the whole production process consists of multiple preparation processes and deformation processes, and has the characteristics of reciprocating cycle. This will involve  many processes, long production cycle, large metal consumption, low production efficiency, high precision, bright and smooth inner and outer surfaces, no peeling, no cracks, no pits. Different processing methods and corresponding auxiliary processes are selected according to the processing properties of the metal, the p
