8) Chemical resistance
|
Our publication“Chemical Resistance of NIROSTA Steels”contains tables giving some guide to chemical resistance.
|
NIROSTA 4116 belongs to group 1 in the publication.
|
9) Processing
|
This material can be heat treated to achieve high strength values due to its high C content.
|
Machining is comparable to that of an unalloyed structural steel. Tools should be made of good quality high-speed steel or carbide.
|
|
Heat tints or scale from heat treatment reduce corrosion resistance and should be removed chemically (e.g. pickling baths or pickling pastes) or mechanically (e.g. by grinding or blasting with glass beads or iron- and sulfur-free quartz sand.
|
NIROSTA 4116 can be polished.
|
10) Welding
Weldability: NIROSTA 4116 is not suitable for welding.
11) Applications
NIROSTA 4116 is used for parts which are subject to wear, e.g. for high-quality table and kitchen knives, penknives blades and meat knives. Adding vanadium improves wear resistance. The addition of Mo improves corrosion resistance compared to standard martensitics.
