Birta Qaabaysan ee DIN 1.2311 P20
Sharaxaad Gaaban:
DIN 1.2311″ waa nooc caadi ah oo bir ah oo caaryada ah, oo badanaa loo yaqaan birta P20. P20 waa bir caaryada daawaha yar oo loo yaqaan farsamaynteeda wanaagsan iyo iska caabbinta xirashada, oo si caadi ah loogu isticmaalo soo saarista caaryada balaastikada ah iyo caaryada shubka ee la shito.
Birta Qaabaysan ee DIN 1.2311 P20:
DIN 1.2311 P20 Mold Steel waa bir caaryo ah oo si caadi ah loo isticmaalo, oo si weyn loogu isticmaalo soo saarista caaryada balaastikada ah iyo caaryada shubka. DIN 1.2311 P20 Mold Steel waxay leedahay waxqabad goyn oo heer sare ah iyo mashiin, taasoo sahlaysa in loo farsameeyo qaabab kala duwan oo caaryo ah. Ka dib daaweynta kulaylka habboon, DIN 1.2311 P20 Mold Steel waxay gaari kartaa adkeysi sare iyo iska caabin heer sare ah oo xirasho, oo ku habboon soo saarista caaryada leh shuruudo sare. DIN 1.2311 P20 Mold Steel waxaa badanaa loo isticmaalaa codsiyada caaryada kala duwan sida caaryada duritaanka, caaryada fidinta, caaryada shubka, iyo saldhigyada caaryada.
