805m20 Alloy Structural Steel Mechanical And Physical Properties - China
price: 304.00 Dollar US$
Mechanical Properties and Physical Characteristics of 805M20 Alloy Structural Steel Mechanical Properties
Strength: Tensile strength ≥980 MPa, yield strength ≥785 MPa, significantly higher than ordinary carburized steel.
Toughness: Elongation ≥9%, reduction of area ≥40%, impact energy ≥47 J; core toughness effectively absorbs dynamic impact energy.
Hardness: After carburizing, the surface hardness of 805M20 alloy structural steel can reach HRC 58-62, while the core hardness remains HB≤197, achieving a balance of rigidity and flexibility.
Physical Properties
Thermal Stability: Suitable for operation in environments below 250℃; short-term temperature resistance supports some high-temperature applications.
Machining Performance: Good machinability in the annealed state; 805M20 alloy structural steel is suitable for precision machining.
