DIN 17350 Grade 102Cr6 quenched and tempered (+QT)
DIN 17350 Grade 102Cr6 quenched and tempered (+QT) introduction
102Cr6 is an oil-hardening tool steel. It achieves at least 60 HRC in hardened condition. The steel is particularly ductile and wear resistant.
Application: smaller up to medium cutting tools, pressure and beading rolls, shear and roll shear cutter, cold roller, drawing mandrels, thread tools, wood and paper machining tools, measuring tools and gages, center punch cone points and similar tools.
