Description
marker
The Chinese company Qianchui Mechanical, using military technology, produces heat-resistant special steel
Special steel: using our own developed heat-resistant special steel QC600
Produced sizes: diameter Φ50～Φ360mm × length ≤5000mm
Technological process: EAF+CP+VD vacuum refining of 8～12-ton large ingots + forging of the billet on a 4500 ton press + forging of a circle on a 1,800 ton forging press + post-forging normalization + pre-heat treatment by tempering + standard case hardening + multiple low tempering + surface shot blasting + inspection and delivery to warehouse
The deformation ratio of special steel is >8:1, the grain size is ≥8 points, and ultrasonic testing fully complies with the requirements.
Strength indicators: surface hardness HRC60～65
High temperature properties: withstands operating temperatures up to 600°C without softening or deformation, while the hardness is maintained at the level of HRC55～60, which fully guarantees the performance characteristics of parts under conditions of high temperatures and high loads.
To buy a good piston, only accept Qianchui.
Qianchui pistons are military quality.
