Material Notes:
LESCALLOY 17-4 VAC-ARC steel is a precipitation hardening martensitic stainless steel. A wide range of mechanical properties is available via simple aging within a 900-1150°F (482-621°C) temperature range. Vacuum arc remelting provides low gas content, superior cleanliness and optimum transverse properties.H900 Condition - Information Provided by Timken Latrobe Steel.Timken sold Latrobe in December 2006. They are now Latrobe Specialty Steels Co.
