components for chain elevators / shackles RC4 and RC5

RC 4
Highly wear resistant chain shackles, marked RC 4, produced according to DIN 745, manganese alloyed (e.g. 21Mn4Al), machined at the distance plate contact surface, surface hardness min. 700 HV measured 0,25 mm below the surface at the rounding, carburizing depth HTÄ 0,1d ± 0,01d, hardening depth EHT at approx. 0,06d more than 550 HV related to dimension d1, proof strength 125 N/mm2, breaking strength 280 N/mm2.
RC 5
Highly wear resistant chain shackles, marked RC 5, produced according to DIN 745, made of chrome and nickel alloyed steel, machined at the distance plate contact surface, surface hardness min. 700 HV measured 0,25 mm below the surface at the rounding, hardening depth EHT at approx. 0,06d more than 550 HV related to dimension d1, proof strength 125 N/mm2, breaking strength 300 N/mm2.
