Steel characteristics
- Hydraulic breaker that crushes rocks continuously with excellent impact toughness, wear resistance and fatigue
- Excellent carburizing and Q/T heat treatment characteristics
Applied parts
- Chisel: the part that directly crushes rocks
- Piston: reciprocating force that hits chisel so that chisel can crush rocks
- Cylinder: the center of breaker where hydraulic circuit is located to reciprocate piston
- Through bolt: To fix front head, cylinder and back head of breaker body
Type of steel used
- AE4140 Mod., SNCM616V, SCM415, SCM420, 16MnCr5, 20MnCr5, SNCM630
Technology development
- Internal quality improvement: Internal density improvement througt forging/rolling process optimization EMS optimization during continuous casting process
- Usage lifetime improvement: impact resistance, wear resistance improvement by grain refinement and alloy design optimization (excellent carburizing and Q/T heat treatment)
