The advantages of this plain-finished steel scaling bar are as follows:
High-strength forging process
This plain-finished steel scaling bar,
manufactured by Tianlong, uses a forging process that results in a denser internal metal structure. Its impact toughness is significantly higher than that of ordinary cast chisel heads.
The internationally advanced plain surface treatment reduces impurity adhesion and enhances corrosion resistance. These performance characteristics extend its service life in applications such as mine tunnel cleaning and concrete surface roughening.
Although the plain finish lacks a coating, the steel's inherent trace chromium content ensures more stable corrosion rates in underground mines compared to painted surfaces. Painted finishes are prone to "accelerated local corrosion" after impacts, whereas the plain finish maintains more predictable overall durability even with surface scratches.
Leading hardness and strength parameters
With a hardness of ≥50HRC (far exceeding the industry average of 45HRC), this scaling bar resists edge deformation effectively. Its tensile strength of 809–1100 MPa and yield strength of 750–900 MPa ensure it can withstand accidental impacts against hard rocks without fracturing.
These properties make it ideal for critical applications like bridge bearing surface cleaning and large equipment foundation removal, serving as a reliable tool in engineering projects.
Steel Scaling Bar with Plain Finish: Balanced parameter design
The scaling bar's 50HRC hardness and 800 MPa-class tensile strength create an optimal physical balance: ensuring efficient cutting during operation while minimizing the risk of brittle fracture (a common issue in high-hardness steel with insufficient tensile strength).
Additionally, the plain surface treatment reduces the coefficient of friction, enhancing grip safety for operators.
Steel Scaling Bar with Plain Finish:Lightweight material
Leveraging high-strength steel (800 MPa class), this scaling bar is lighter than conventional steel bars of the same length. This design reduces operator fatigue during 8-hour continuous operations, minimizing the risk of occupational strain injuries.
