Muhtasari wa baa ya pande zote za chuma cha Spring
Baa ya pande zote ya chuma cha spring inafaa kwa aina mbalimbali za matumizi ya spring ikiwa ni pamoja na chemchemi za gorofa, vifungo, visu, vile vya daktari, vile vya kuona, zana za kilimo, misumeno ya kukata kuni, shimu, visu, vile, shim, washers, zana za uashi. Wakati joto linaposhughulikia halijoto za EN42, ikijumuisha kasi ya kupokanzwa, kupoeza na nyakati za kuloweka, n.k. zitatofautiana kutokana na mambo kama vile umbo na ukubwa wa kila sehemu. Mazingatio mengine wakati wa mchakato wa matibabu ya joto ni pamoja na aina ya tanuru, vifaa vya kuzima, na vifaa vya kuhamisha vifaa. Tafadhali wasiliana na mtoa huduma wako wa matibabu ya joto kwa mwongozo kamili juu ya matibabu ya joto ya vyuma vya spring.
