20CrMo otentha adagulung'undisa zitsulo pepala

zitsulo zozungulira zitsulo zimagwiritsidwa ntchito kwambiri popanga makina, kupanga autombile, njanji, makina amigodi, makina a petoleum, makina aulimi ndi zomangamanga monga mitundu yonse yazitsulo, zomangira, ndodo zolumikizira, zida za hardware, magiya, zigawo zokhazikika, zomangira zomangira, zomangira. zida zamagalimoto ndi zaulimi, manja akunja ndi amkati, odzigudubuza ndi mipira yonyamula.
GB 20CrMo zitsulo ndi mtundu wa chitsulo cha aloyi cha ku China cha zomangamanga ndi zomangamanga, zomwe nthawi zambiri zimagwiritsidwa ntchito pozimitsa kapena kutenthetsa kapena kuzimitsa ndi kuzimitsa. Zinthu za 20CrMo zili ndi mphamvu zotentha kwambiri, zowuma bwino, zopanda kupsa mtima, kuzizira kwapulasitiki, kukhazikika bwino komanso kutsekemera.

Mapulogalamu

20CrMo aloyi zitsulo ntchito kupanga zosawononga TV zipangizo mankhwala ndi mipope kuthamanga kwambiri, fasteners, turbines nthunzi, boiler boiler ndi forgings ndi kutentha ntchito pansi 250 °C, ndi mbali zofunika carburizing monga magiya ndi shafts mu makina ambiri. . Itha kugwiritsidwanso ntchito m'malo mwa chitsulo cha 1Cr13 kupanga kukakamiza kwapakatikati, ma turbines otsika otsika kwambiri m'malo otentha kwambiri a nthunzi zone.

Kufotokozera kwa Chithandizo cha Kutentha

• Kutentha koyamba kozimitsa: 880 °C (Chozimitsa: madzi, mafuta)
• Kutentha Kutentha: 500 ° C (wothandizira - madzi, mafuta)

Maphunziro Ofanana

20CrMo zinthu zofanana ndi US ASTM, European Germany DIN EN, British BS EN, France NF EN, Japanese JIS, ndi ISO standard. (Kuti zifotokoze)
