Auto parts
Automotive parts typically require high strength and durability to withstand various road conditions and mechanical stresses. The selection and design of materials focus on providing sufficient strength and durability to ensure long-term reliability of the components. Ductile iron materials are well-suited for products that demand a combination of toughness and strength. Commonly used steel grades include S50C, S55C, S65C, SK85M, SUP6, SUP10, 1065, and 1085.
