310S Heat Treatment Basket Castings

Product Name: 310S Stainless Steel Heat Treatment Basket Castings

(Custom Engineered for High-Temperature Furnace Applications)

Precision-cast ZG45Cr25Ni20Si2 (310S equivalent) heat treatment baskets are designed for extreme temperature environments up to 1150°C continuous operation. These custom baskets offer superior oxidation resistance and creep strength for demanding applications in annealing, carburizing, and brazing processes, with 3-5x longer service life than standard 304 baskets.
