FAQ
Q1: Me yasa amfani da Boron Karfe maimakon 4140 don kusoshi?
A1: Farashin & Tsari. Don diamita a ƙarƙashin 30mm, Boron karfe (kamar 15B35) na iya cimma daidaitattun kaddarorin Grade 10.9 kamar 4140 amma a farashin kayan abu mai mahimmanci. Hakanan yana da sauƙin sanyi ({8}} siffa (sanyi) fiye da 4140, yana haɓaka saurin samarwa.
Q2: Menene "Spheroidize Annealing" (SA)?
A2: Yana da maganin zafi wanda ke sassaukar da karfe kuma ya haifar da tsarin carbide na duniya. Wannan yana da mahimmanci don Wayar Cold Heading Quality (CHQ). Idan ba tare da SA ba, wayar zata yi wuya sosai kuma zata fashe kan labarin ya mutu yayin masana'anta.
Q3: Menene 20MnTiB ake amfani dashi?
A3: 20MnTiB wani babban darajar Sinanci ne da aka ƙera musamman don Manyan Hexagon Head High- Ƙarfin Ƙarfi da ake amfani da shi wajen gina ginin ƙarfe ( gadoji, skyscrapers). Yana ba da kyakkyawan tasiri mai ƙarfi- zafi.
Q4: Shin Boron karfe weldable?
A4: Ƙananan maki na carbon (kamar 10B21) suna da kyakkyawan walƙiya. Koyaya, manyan makin carbon (kamar 50B) ko zafi{5}}asashen da aka yiwa magani suna da wahalar walda ba tare da tsattsage ba kuma suna rasa halayensu masu zafin rai.
