The Chinese company Qianchui Mechanical, using military technology, produces large parts for unmanned aerial vehicles
Special steel: using our own developed 616S special alloy steel
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 HRC58~61, core hardness HRC36~42
Impact strength indicators: AKU ≥108 J, fully meet the performance requirements of large parts for unmanned aerial vehicles: high surface strength, high wear resistance, high core toughness, “hard outside, soft inside.”
To buy a good piston, only accept Qianchui.
Qianchui pistons are military quality.
