FOR ALL KINDS OF HOT WORK TOOL APPLICATIONS
Uddeholm Orvar Supreme is Uddeholm’s trusted premium H13 steel for all kinds of hot work tool applications. Proven over and over again, Uddeholm Orvar Supreme has stood the test of time and remains well known in the tooling industry for its high and reliable performance and ease of machining. Orvar Supreme was rated to NADCA (North American Die Casting Association) tool steel standard grade A, premium H13, 10.8 Joules/8 ft-lbs avg toughness and ASTM grain size 7 or finer.
The upgraded Orvar Supreme 16J is now found in the NADCA#207 document in Band B for toughness and cleanliness. The new min/avg of 16 joules for delivered, soft annealed material is Uddeholms own higher-level standard, but it still remains at the NADCA Band B level.
