Product Overview
CAST-STRUC-1000 Structural Casting is a high-integrity, heavy-duty ferrous component engineered for demanding load-bearing applications in industrial infrastructure, power generation, and oil & gas systems. Manufactured to ASTM A27 Grade 70-36 specifications, this casting delivers a minimum tensile strength of 70 ksi (483 MPa) and yield strength of 36 ksi (248 MPa), ensuring structural reliability under dynamic and static loads. Produced via precision sand mold casting—a proven method for complex geometries and large-scale parts—each unit undergoes full ASME B16.34 compliance verification for pressure-containing service suitability. As a premium-grade structural casting, CAST-STRUC-1000 supports custom engineering integration, with a maximum net weight capacity of 1000kg structural casting per piece, enabling monolithic fabrication of frames, bases, brackets, and support housings.
