Steel 1.2365 - RP

1.2365 - RP:
high thermal resistance and tempering resistant

1.2365 – RP steel is a Cr-Mo-V alloyed hot-work tool steel with very high thermal resistance and tempering resistance, water coolable due to good thermal conductivity, so not sensitive to thermal shock. RP is very good for hobbing.

Properties of steel type 1.2365 – RP
 
  • High thermal resistance .
  • Tempering resistance .
  • Not sensitive to thermal shock .
  • very good for hobbing ery good for hobbing.
The most common applications for steel type 1.2365 – RP are:
 
  • Extrusion press tools for steel and heavy metal processing, such as pipe extrusion rams, die holders and inner liners
  • Compression moulding dies for heavy metal processing
  • Tools in forging presses such as die inserts, mandrels, forge jaws and stems for steel processing
  • Piercer heads
  • Piercers
  • Push bench rollers in steel pipe production
