Tsanangudzo
Martensitic Stainless simbi inoshingirira mukuora. 1.2085 simbi inotaridza yakanakisa kusakara mukuora mumamiriro akaomeswa nenzvimbo yakakwenenzverwa kuti ipe girazi kupera. Zvivakwa: Magnetizable steelm yakanaka mechanicha kuramba uye kuoma, yakanakira kugadzira zvinhu izvo zvinofanirwa kuramba kune hutsinye mapurasitiki, yakanaka chishandiso machinability nekutenda kune yayo sarufa yemukati, yakakodzera kushanda mumhepo yakanyorova uye mwando, yakakodzera kupukuta, kupfeka uye corrosion chiratidzo, uye yakanyatsogadzikana dimensionally panguva yekupisa kurapwa.
Applications
Mhando dzese dzekucheka maturusi - anofa uye anofa-zvivharo muindasitiri yepurasitiki sePVC, mapanga, shears, midziyo yekuvhiya, mold dzekugadzira mapurasitiki, pamwe nemidziyo yekuvhiya uye yekuyeresa geji.
