Product Description

20CrMn 1.7147 Engineering Seamless Steel Tube


1: DIN 1.7147 steel introduction

     1.7147 is a European standard carburized steel (surface hardening steel) with high strength toughness and good hardenability. Small quenching deformation, low temperature toughness and good machinability, but low welding performance. It is generally used after carburizing, quenching or quenching and tempering.
