EDRO UltraChem® ESR #16 Precipitation Hardening Stainless Mold Steel

Ultrachem ESR® is a chromium-nickel precipitation-hardening stainless steel, a modified PH alloy grade, which is characterized by exceptional polishability, exceptional corrosion resistance, uniform hardness in all dimensions, excellent compressive strength, simple low temperature heat treatment with small dimensional change, good weldability, excellent toughness, and excellent EDM machinability.
Ultrachem ESR® is normally supplied in a fully heat treated condition, age hardened to 38 or 42 HRC.
Ultrachem ESR®'s excellent corrosion resistance reduces both maintenance costs and production costs. Consistently high molding productivity is assured since cooling channels are not subjected to corrosion and loss of cooling efficiency.
Ultrachem ESR® is particularly suitable for applications where high surface finishes are required. It is also recommended for use in long-life molds subjected to severe working conditions, including corrosive materials and atmospheres, high stresses and indentation experienced in today's fast cycling molding operations.
