Pwodwi Entwodiksyon

DIN1.6587/18CrNiMo7-6 se yon kabòn ki ba, ka redi (karburize) asye ki gen 1.8 pousan chromium - nikèl - molybdène kòm ajan ranfòse dapre EN 10084. Karakterize pa gwo fòs nwayo ak severite nan mwayen ak gwo seksyon. ak ka dite jiska Rc62 lè karburize, fè tèt di ak tanperaman, epi li se tou yo itilize nan zòn nan pati lou ak gwo tansyon Kovèti pou ak gwo demand sou severite nan rupture nwayo nan 1050-1350N / mm2.DIN1.6587 / 18CrNiMo{{14 }} se menm jan ak 17CrNiMo6 asye, jeneralman apwovizyone nan kondisyon an rkwit ak yon dite brinell maksimòm de 229
