: Key characteristics include yield strength (stress at which permanent deformation begins), ultimate tensile strength (maximum stress capacity), ductility (capacity for plastic deformation), and toughness (resistance to fracture). End of Article
: Specifically engineered for hardness and heat resistance. These are the preferred materials for drilling, stamping, and cutting equipment. Conclusion : Specifically engineered for hardness and heat resistance
