Properties of
Tenfaye Steel Casting Parts
Steel casting parts can be produced in a wide range of properties. The physical properties of steel castings vary significantly depending on the chemical composition and heat treatment. They are selected according to the performance requirements of the intended application.
The ability of a material to resist abrasion. The carbon content determines the steel's maximum hardness or hardenability.
The amount of force required to deform a material. Higher carbon content and hardness result in steel that is stronger.
The ability of a metal to deform under tensile stress. Lower carbon content and lower hardness cause the steel to be more ductile.
The ability to withstand stress. Increased ductility is usually associated with better toughness. Strength can be adjusted by adding alloying metals and heat treatment.
Resistance of the material to friction and use. Cast steel has the same wear resistance as wrought steel of similar composition. Adding alloying elements such as molybdenum and chromium can improve wear resistance.
Material resistance to oxidation and rust. Cast steel has the same corrosion resistance as forged steel. High-alloy steels with high chromium and nickel contents are highly resistant to oxidation.
The ease with which a steel casting can change shape by removing material through machining (cutting, grinding, or drilling). Machinability is affected by hardness, strength, thermal conductivity and thermal expansion.
The ability of a steel casting to be welded without defects. Weldability primarily depends on the chemical composition of the steel casting and heat treatment.
- High temperature properties
Steels operating at temperatures above ambient are susceptible to deterioration of mechanical properties and premature failure due to oxidation, hydrogen damage, sulfite scale, and carbide instability.
- Low temperature properties
The strength of cast steel decreases sharply at low temperatures. Alloying and special heat treatments can improve a casting's ability to withstand stress and stress.
