16MnCr5 (UNI EN 10084)

 

PROPERTIES AND EMPLOYEMENTS
IT IS AN EXCELLENT CASE-HARDENING STEEL THAT COMBINES A GOOD TOUGHNESS IN THE NUCLEUS WITH AN ELEVATED HARDNESS OF THE CASE-HARDENED LAYER.
IT CAN SUBSTITUTE STEELS WITH NICKEL-CHROMIUM, IT HAS A MEDIUM-LOW HARDENABILITY, FOR THIS REASON IT CAN GUARANTEE A GOOD RESISTANCE FOR A THICKNESS UP TO MM 20.
MOREOVER, IT HAS A GOOD MACHINABILITY AT THE SOFT-ANNEALED CONDITION.

Steels

Our steel always comes from the same European steelworks, which guarantee a continuity for what concerns quality. The constant quality of the supplies allows to have repetitive parameters in mechanical processing and a greater control over deformations during heat treatment.

Machining

Precise cuttings of small and big series are guaranteed by the employement of latest generation automatic saws that were projected and realized in order to guarantee precision standards required by customers, reducing processing wastage.
