KU 4
Highly wear resistant chain brackets, marked KU 4, produced acc. DIN 745 / 5699, material age resistant fine grained heat treatable steel, at
the distance plate contact surface machined, pivots adjusted, heat treated to a tensile strength of 800 - 1.200 N/mm2 measured at the back of
the bracket, inductively hardened at the inside load bearing roundings, surface hardness more than 600 HV measured 0,25 mm below the surface,
hardening depth Rht 0,1d min. 550 HV5 + 0,03d related to dimension d1, proof strength 125 N/mm2, breaking strength 280 N/mm2.
KU 5
Highly wear resistant chain brackets, marked KU 5, produced acc. DIN 745 / 5699, material age and corrosion resistant chrome-molybdanealloyed
super-refined steel, at the distance plate contact surface machined, pivots adjusted, heat treated to a tensile strength of 1.000 - 1.200
N/mm2 measured at the back of the bracket, inductively hardened at the inside load bearing roundings, surface hardness more than 600 HV measured
0,25 mm below the surface, hardening depth Rht 0,1d min. 550 HV5 + 0,03d related to dimension d1, proof strength 240 N/mm2, breaking
strength 400 N/mm2. |
