Product brief introduction

5CrMnMoIs on the basis of medium carbon steel main add Cr, Mn, Mo, and developed into three elements, can also be seen as the 5 crnimo steel replaced by Mn element and form of the Ni elements.

Technical Equipment

5 crmnmo steel compared with 5 crnimo steel, although the strength is not reduced, but the normal temperature and high temperature toughness and plasticity decreases a lot, and the hardenability and thermal fatigue property is also slightly lower.
In addition, 5 crmnmo steel adding Mn, Mo element, little older steel overheating sensitivity.
In addition, Cr elements exist in the steel to produce certain steel oxidation resistance and corrosion resistance.
