Ugitech introduces a stainless steel, UGIMA® 4116N which is extremely hard, thanks to the addition of nitrogen, and much more resistant to corrosion than standard-grade steel as EN 1.4125 (AISI 440C) and EN 1.4112 (AISI 440B). Combined with improved machinability, designers, steel producers and users of parts subject to heavy wear and tear, profit from a true competitive advantage.
In introducing this new development, Ugitech expands the range of applications of special steel UGI® 4116N developed for hard edged cutting tools and leverages significant improvements in productivity in steel processing. UGIMA® 4116N, a new corrosion resistant steel, is a competitive alternative to the conventional martensitic steel grades commonly used such as EN 1.4112/AISI 440B and EN 1.4125/AISI 440C. Both standard materials have high hardness values. However, due to their high carbon content (0.9% and 1.0%, respectively) they contain primary carbides and thus their corrosion resistance is comparatively low and their resistance to impact loads even lower.
57 HRC when tempered with UGIMA® 4116N has a comparable hardness value to that of the materials EN 1.4112/AISI 440B and EN 1.4125/AISI 440C. By adding nitrogen (0.1%) Ugitech it improves the corrosion resistance of stainless steel containing carbon. Resistance to pitting has a potential of 200 mV/ECS (in NaCl 0,02 M at 23°C and pH = 6,6) in a quenched and tempered state and is thereby much more resistant to pitting corrosion than comparable products.
