SCr240 is a low-alloy structural steel material with high hardenability, no temper brittleness, good processability, and little tendency to form cold cracks. It also has good machinability and cold strain plasticity and is effective when used in the tempered or carburized and quenched state. SCr 420 is also a low alloy steel, usually used to manufacture mechanical parts, bearings, gears, sprockets, etc. The following is a brief introduction to the characteristics of SCr 420 in terms of characteristics, execution standards, chemical composition, mechanical properties, and applications.
SCr240
SCr240 Japanese JIS G4051 standard
SCr240 is low hardenability carburizing steel
SCr240 is often used to manufacture high-pressure pipes and various fasteners working in non-corrosive media and media with operating temperatures below 250°C and nitrogen-hydrogen mixtures, as well as some relatively carburized parts, such as gears and shafts. When using this material, reasonable heat treatment and surface treatment need to be carried out according to specific working conditions to ensure its performance.
Characteristic
SCr 420 has certain strength and toughness, and good wear resistance and fatigue resistance. At the same time, it also has good weldability and processability.
Implementation Standards
The implementation standard of SCr 420 is JIS G4053-2008, which stipulates the chemical composition, mechanical properties, and application scope of low alloy steel.
Mechanical Properties of SCr 420
Tensile strength: ≥980 MPa
Yield strength: ≥785 MPa
Elongation: ≥9%
Impact toughness: ≥78 J/cm2
Application
SCr240 lost wax investment casting is widely used in manufacturing mechanical parts, bearings, gears, sprockets, etc. It is widely used in automobiles, machinery manufacturing, bearing manufacturing, and other fields.
