Chii Chinonzi Simbi Inoshandiswa Nemaoko?
Simbi Inoshandiswa Pakuchekerera (Free-Cutting Steel) izita remadunhurirwa resimbi yekabhoni ine zvimwe zvinhu zvinosanganisa simbi nechinangwa chekuvandudza mashandiro ayo uye kudzora machipisi. Inoshandiswawo sezita remadunhurirwa rekuti zvinhu zvinochekerera (Free-Cutting) kana kuti zvinhu zvinochekerera (Free-Cutting).

l11xx nhevedzano: huwandu hweSulfur (S) hunowedzerwa kubva pa0.05% musimbi dzisina kabhoni kusvika pa0.1%. Hunowedzera 20% pakugona kwayo kugadzira kana zvichienzaniswa nezvinhu zvakafanana mu10xx series. Kune rumwe rutivi, simba rekudhonza rinoderera neinenge 10%, uye zvinhu zvacho zvinopfava zvakanyanya.
l12xx dzakatevedzana: Kuwanda kwesarufa (S) kwakawedzera kusvika pa0.25%, uye huwandu hwePhosphorus (P) hwakawedzera kubva pa0.04% mu10xx series kusvika pa0.5%. Nekuda kweizvozvo, kugona kwekugadzira zvinhu kunowedzera ne40% pamutengo wekudzikira kwehunhu hwemakanika.
lSAE 12L14 chinhu chemahara Kucheka simbi uko Phosphorus inotsiviwa ne0.25% yeLead (Pb), izvo zvinowedzera mashandiro emuchina ne35%. Kuvandudzwa uku kunoitika nekuti Lead inonyunguduka panzvimbo payo painochekwa, nokudaro ichideredza kukweshana uye ichipa mafuta echisikigo. Zvisinei, vagadziri vazhinji vezvinhu nezvitoro zvemichina vanoedza kudzivirira kuwedzerwa kwelead nekuda kwekukuvadzwa kwezvakatipoteredza uye njodzi dzehutano.

Jindalai Simbi ikambani inogadzira simbi yakazara uye inotungamira mukugadzira, vatengesi, vanotumira kunze kwenyika, uye vanogovera zvigadzirwa zvesimbi zvakaita semapaipi, machubhu, bhaa netsvimbo. Zvigadzirwa zvesimbi zvatinopa zvinofanirwa kugadzirwa nezvinhu zvemhando yepamusoro uye zvinotenderwa zvizere nezvinodiwa nemaindasitiri zvakaita seASTM neASME kana zvimwe zvinodiwa.Jindalai Simbi Tengai uye chengetai zvinhu zvakawanda zveASTM 12L14, AISI 12L14, SAE 12L14 (SUM24L / 95MnPb28 /Y15Pb) zvemakanika zvakaita semidziyo nemamita, zvikamu zvewachi, mota, chishandiso chemuchina nedzimwe mhando dzemichina pakushandisa zvikamu zvakajairwa, zvakaita semabhaudhi, chishandiso chekucheka, bushing, pini, uye sikuruu yemuchina, kuumba kwepurasitiki, michina yekuvhiya neyemazino, nezvimwewo.
