Kwicingo le-poly wire, sisebenzise i-stainless steel # 304A ukwenza i-poly poly wire, i-stainless steel wire ye-poly wire kufuneka ibe nokusebenza okungafunekiyo okungafunekiyo kunye nokuqhuba kakuhle, ke umgangatho wocingo okanye ucingo lwethu lwe-poly: GB4240-2007 ， Umxholo we-nickel ongekho ngaphantsi kwe-8%, umxholo we-chromium ongekho ngaphantsi kwe-15%, ngaphandle koko, ucingo lwentsimbi olungenasici lwentambo ye-poly luya kuba lula kwaye lunokuziphatha okungaphantsi. ngaphandle koko, i-stainless steel wire ye-poly wire kufuneka ibe yinkqubo ye-hydride (inkqubo yomsindo), ngaphandle koko, ucingo lwensimbi engenasici luya kugoba lula.

ifumaneke ngobubanzi bentsimbi engenazingcingo yocingo oluninzi ngolu hlobo lulandelayo:

Φ0.16mm ucingo lwentsimbi engatyiwa, luqhele ukutshintshwa ngu Φ0.15mm
Kwi-Φ0.15mm, ukunyamezela yi-0.005mm, oko kukuthi Φ0.145~Φ0.155mm

Φ0.20mm ucingo lwensimbi engenasici, ukunyamezela yi-0.01mm, oko kukuthi Φ0.19mm~Φ0.21mm,

Φ0.40mm intsimbi engenasici, endaweni yayo yi -0.35mm, Φ0.37mm

Φ0.38mm ucingo lwentsimbi engenastainless, le ayifumaneki, iqhele ukutshintshwa ngu Φ0.32mm
