ST52 alloy steel chitoliro chitsimikizo chenicheni cha khalidwe
Zitsulo zopanda aloyi zimatengedwa ngati chitsulo chokhazikika, chomwe chimadziwika kwambiri ndi mphamvu zamakokedwe komanso zokolola. Amagwiritsidwa ntchito pomanga, zomangamanga mobisa, kapangidwe ka mlatho, kapangidwe ka m'madzi, kupanga zidebe, kupanga magalimoto ndi makina.
Gulu lachitsulo nthawi zambiri limapangidwa ndi kalata st, mtengo wamtengo wapatali wachitsulo ndi index index. Mwachitsanzo, St52-3. Kwa kalasi yachitsulo yokhala ndi zofunikira zina zosankhidwa za njira ya deoxidation, chizindikiro chofanana (U kapena R) chimayikidwa patsogolo pa kalasi yachitsulo.
Mwachitsanzo: ust37-2 kapena rst37-2
Mtundu wawung'ono st37-2 st37-3u st37-3n m'malo 20 zitsulo
St37 ndi mtundu waku Germany, koma ndi mtundu wamba komanso mitundu ingapo yaying'ono.
Monga st37-2, st37-3u, st37-3n, rst-2, ust37-2, etc.
St37-2 ndi mtundu wazitsulo za carbon structural ku Germany
Nkhaniyi ndi yofanana ndi zitsulo za carbon structural Q235B (nambala yakale ya mtundu: a3-b) ku China
Kuphatikiza apo, chifukwa chitsulo ichi ndi chofanana ndi chitsulo chapamwamba cha China cha carbon structural steel 20, chingathenso kusinthidwa ndi zitsulo 20.
Chitoliro chachitsulo chosasunthika chokwera kwambiri komanso chitoliro cha boiler chothamanga kwambiri ndi mtundu wa chitoliro cha boiler, chomwe chili mgulu la chitoliro chopanda chitsulo. Njira yopangira ndi yofanana ndi chitoliro chosasunthika, koma pali zofunikira zokhwima pazitsulo zachitsulo zomwe zimagwiritsidwa ntchito popanga chitoliro chachitsulo. Machubu a boiler othamanga nthawi zambiri amagwiritsidwa ntchito pansi pa kutentha kwambiri komanso kupanikizika kwambiri. Machubu opopera oponderezedwa kwambiri amagwiritsidwa ntchito makamaka popanga machubu otenthetsera, machubu otenthetsera, machubu a mpweya, machubu akulu a nthunzi, ndi zina zambiri zama boiler othamanga kwambiri komanso othamanga kwambiri.
