- Introduction
Physical property
Strength of Extension: 47Kgs/mm2
Coeffcient of Elongation: 17%
Yield Point: 110kgs/mm2
Vicket-hardness: HV80
Usage: Test, measuring, lineation, equipment installation, construction of industrial engineering.
Characteristric:
Convenient for using: the operator could move it easily.
Non deforming: The yield point of general steel material is 30kgs/mm2, and yield point of general cast-iron piece is 38kgs/mm2. The yield point of this material is 110kgs/mm2. Its' anti-bending target is much higher than other materials.
Easy to maintain: Keep it hang or level position. The parallelism and straightness of it could not be changed after long period leveling position.
Non-rust: Don't oiling in the use period. If it will not be used for a long-term, just smear thin-layer general industrial oil gently for keeping.
