ASTM A536<\/a> Grade 70-50-05 is a high-strength ductile iron (also known as nodular or spheroidal graphite iron) with excellent mechanical properties, including a tensile strength of 70 ksi (485 MPa), yield strength of 50 ksi (345 MPa), and 5% elongation. This grade is widely used in automotive, agricultural, and industrial applications due to its superior ductility, impact resistance, and machinability. Its unique microstructure, featuring spherical graphite nodules, enhances durability and fatigue resistance.<\/p>\n
