AISI 1045 1.1191 C45 S45C
AISI 1045 steel has a low through-hardening capability with only sections of around 60 mm in size being recommended as suitable for tempering and through-hardening. However, it can be efficiently flame- or induction-hardened in the normalized or hot rolled condition to obtain surface hardnesses in the range of Rc 54 - Rc 60 based on factors such as section size, type of set up, quenching medium used etc.
AISI 1045 steel lacks suitable alloying elements and hence does not respond to the nitriding process.

Finishing rolling process:
Finishing rolling is a process to obtain higher precision and better surface quality by rolling the heat-treated seamless steel pipe multiple times. The specific steps include: heat treatment - pickling - cooling - finishing rolling - sizing - cutting - length - inspection - packaging. Finishing rolling can improve the precision, surface quality and mechanical properties of steel pipe.
Cold drawing process:
Cold drawing is a process of drawing the heat-treated seamless steel pipe one by one in a cold state to obtain high precision, high surface quality and high mechanical properties. The specific steps include: heat treatment - pickling - cooling - cold drawing - deoxygenation - wet pickling - cold water washing - leveling - straightening - pickling - cold water washing - oxide skin - cold drawing - sizing - straightening - pickling - cold water washing - deoxygenation - polishing - inspection - packaging. Cold drawing can significantly improve the dimensional accuracy, surface quality and mechanical properties of steel pipes.
Hot rolling production process:
Hot rolling is the process of heating the blank to a certain temperature, and then forming it into seamless steel pipe through multiple rolls. The specific steps include: heating - rolling - roll probe - sizing - cooling - trimming - rod breaking - inspection - packaging. Hot rolling can produce seamless steel pipes with large diameters and wall thickness, but the accuracy and surface quality are not as good as fine rolling and cold drawing.
These three processes have different applications in the production of seamless precision steel pipes, and the specific choice depends on the required dimensional accuracy, surface quality and mechanical properties.
