440M is a very new stainless steel grade which has been researched and developed by UGITECH. This grade is written as 1.4116 or UGI4116N or X50CrMoV15 according to EN norm. This grade is a very good grade for heat threatment and for many applications, this grade is better then 440B (1.4112) and 440C (1.4125). 440M has less carbon content then 440B and 440C so 440M material is less biritall. Also low carbon content makes UGI4116N grade better at corrosion resistance, because higher carbon lowers the corrosion resistance. 440M stainless steel grade can be heat threated and hardened up to 57-60 HRC hardness. For high hardness required applications, 440M (UGI4116N) is a perfect choose and 440M grade can be choosen as alternative to 440B (1.4112) and 440C (1.4125) in many applications. 440M material usually used in drills, hand tools, knives and you can find 440M stainless steel ready in Bircelik warehouse.
