Automobile Shock Absorber Cylinder seamless carbon steel Tube

Instruction

TORICH is making Automobile Shock Absorber Cylinder Tube with seamless carbon steel,are produced by carbon steel seamless production method of cold drawn or cold rolling, depending on different sizes and surface requirement. 

Applications: for Auto industry/for machinery use/Oil Cylinder Tube/Motorcycle shock absorber                                                    
Auto shock absorber inner cylinder/Telescopic Cylinders

                                                
Size range: 

O.D.:6-350mm     W.T.:1-35mm      L:max12000mm

Characteristic: High precision with smooth ID tolerance and roughness     

Seamless Carbon Steel Grade and Chemical Compositions:                                                

a Rm: tensile strength;  ReH: upper yield strength; A: elongation after fracture                                                    
b 1Mpa=1N/mm2                                                    
c Depending on the degree of cold work in the finishing pass the yield strength may nearly be as high as the tensile strength.                                                    
For calculation purposes the following relations are recommended:                                                    
for delivery condition +C: ReH ≥0.8 Rm                                                    
for delivery condition +LC: ReH ≥0.7 Rm                                                    
d For calculation purposes the following relation is recommended:ReH≥0.5Rm                                                    
e For tubes with outside diameter ≤30mm and wall thickness ≤3mm the ReH minimum values are 10Mpa lower than the values given in this Table                                                    
Note: Special steel grade is also available, according to customer request.
