1020/S20C Hydraulic Cylinder Steel Tube High Precision Cold Drawn Seamless tube

 

OVERVIEW

 

Carbon steel seamless steel pipe is kind of long steel. Steel pipe has hollow section, which is widely used as pipeline for conveying fluids, such as oil, natural gas, gas, water and some solid materials. Compared with solid steel such as round steel, steel pipe is lighter in weight under the same bending and torsional strength. It is an economic section steel. It is widely used in manufacturing structural and mechanical parts, such as oil drill pipe, automobile transmission shaft, bicycle frame and steel scaffolding used in construction.

 

Honing/Skiving tube has closer dimensional tolerances, better surface finish and higher mechanical properties than corresponding grades of hot finished seamless.

 

APPLICATIONS

 

High Precision Cold Drawned Seamless Steel Tube is used in automotive industry, and in the occasion where the high accuracy, brightness, cleanness of the tube are required.

  • Boiler tube
  • Transport water or fluid
  • Shipping building

Heat Treatment


Annealing
AISI 1020 steel is heated at 870°C - 910°C followed by holding for certain time until the temperature remains constant all over the section. It is then cooled in a furnace.

 

Carburizing
AISI 1020 is heated to between 880°C - 920°C in a suitable carburizing atmosphere followed by holding for sufficient amount of time to produce the needed carbon content and case depth. After this, refining/hardening and tempering processes are carried out to optimize the core and case properties.

 

Core Refining
AISI 1020 steel is slowly cooled and re-heated at 870°C - 900°C followed by holding until the temperature remains constant all over the section and quenching in water, oil or brine.

 

Case Hardening
After performing the core refining process, it is re-heated to 760°C - 780°C followed by holding until the temperature is consistent all over the section. It is then quenched in water.

 

Tempering
AISI 1020 steel is re-heated at 150°C - 200°C followed by holding for certain time until the temperature remains constant throughout the section. It is soaked for 1 hour per 25 mm of section and then cooled under normal atmosphere. By performing the tempering process, the toughness of the case will be improved and grinding cracks will be reduced.

 

Normalizing
AISI 1020 steel is heated at 890°C - 940°C followed by holding until the temperature remains constant throughout the section. It is soaked for 10 - 15 minutes and then cooled in still air.

 

Stress Relieving
AISI 1020 steel is heated to 650°C - 700°C followed by holding until the temperature remains constant all over the section and soaking for 1 hour per 25 mm of section. It is then cooled in still air.
