Smallest work condition temperature for segment bolt should never smaller than -50 degrees

　　Professional excavator segment bolt production manufacturer said the smallest working condition temperature for these excavator segment bolt is about -50 degrees, but if the work condition temperature is smaller, it would causes the segment bolt has a worse plastic property and its strength also can be influence as well. Professional excavator segment bolt production manufacturer also need to indicate that as long as the work condition temperature is beyond three hundred degrees, these excavator segment bolt would easy has the lose efficiency problem, such as has the loosen phenomenon or creep deformation changes.

　　Professional excavator segment bolt production manufacturer said if these excavator segment bolt had been produced with carbon steel and the grade level is ten point nine grade, to guarantee the stabilize strength performance and avoid creep deformation changes, then during the common using period, the biggest work condition temperature should never beyond two hundred and fifty degrees, or it would easy has the elongation phenomenon and broken off problem.
