Outer Diameter: 6mm~720mm ; 1/8’’~36’’
Wall thickness: 0.89mm~60mm
Tolerance: +/-0.05~ +/-0.02
Drawing: Drawing the rolled blank through the die hole into a
section to reduce the increase in length
Rolling: the blank is passed through the gap of a pair of rotating
rollers. Due to the compression of the rollers, the material
section is reduced and the length is increased. This is a common
way to produce steel tubes
Forging: To change the blank into the desired shape and size by
using the reciprocating impact force of the hammer or the pressure
of the press
Extrusion: The blank is placed in a closed extrusion container with
pressure applied at one end to extrude the blank from the specified
die hole to obtain different shapes and sizes
Compared with ferritic stainless steel and Martensitic stainless
steel, duplex stainless steel has higher toughness, lower brittle
transition temperature, better intergranular corrosion resistance
and welding performance, while retaining some characteristics of
ferritic stainless steel, such as high thermal conductivity, small
linear expansion coefficient and superplasticity.Compared with
austenitic stainless steel, its strength is higher, especially the
yield strength is significantly improved, and the intergranular
corrosion resistance, stress corrosion and corrosion fatigue
performance are significantly improved.Therefore, this kind of
steel is widely used in chemical industry, large chemical
containers for transportation, natural gas and petroleum industry,
paper industry, environmental pollution control equipment and so
on.
