2. Nut strength class
Nuts are also categorized into three strength classes: 8, 10 and 12. Different grades of nuts are made of different materials to suit different working environments and load requirements.
3. Material and mechanical properties of nuts
– Grade 10 nuts use 35# high carbon steel, its hardness is HRC28-32, tensile strength ≥ 900 MPa.
– Grade 12 nuts use 40Cr alloy steel, hardness increased to HRC33-38, tensile strength ≥ 1000MPa.
Excavator and bulldozer bolts and nuts are small, but its impact on mechanical properties and safety should not be ignored. I hope the analysis in this article can help you better understand and use these key components to ensure the safe and efficient operation of construction machinery.
