FAQ
Q1: Akin et usaren so Boron Steel imbes ya 4140 parad saray bolts?
A1: Gastos tan Proseso. Parad saray diametro ya kulang na 30mm, say Boron steel (singa say 15B35) et makagamor na parehon Grade 10.9 ya kablian a singa say 4140 balet diad mas abeban gastos ed materyales. Mas mainomay met ya cold-form (cold head) nen say 4140, kanian mas maples so produksyon.
Q2: Anto so "Spheroidize Annealing" (SA)?
A2: Saya so heat treatment ya mamalemew ed asero tan manggawa na globular carbide ya istruktura. Saya so importante parad Cold Heading Quality (CHQ) wire. No anggapoy SA, say alambre et magmaliw ya malet tan nabuyak so heading dies legan ya manggagawa na bolt.
Q3: Antoy uusaren na 20MnTiB?
A3: Say 20MnTiB et sakey a klasikon klase na Tsina ya espisipikon ginawa parad angkakabaleg ya Hexagon Head High-Strength Bolts ya uusaren ed panagpaalagey na bakal ya istruktura (saray taytay, skyscrapers). Mangiyoopresi itan na ekselentin inkapekder ed abeban temperatura.
Q4: Nayarin weld so Boron steel?
A4: Saray abeban grado na carbon (singa say 10B21) et walaan na maong ya weldability. Balet, saray parte ya atagey so carbon grades (singa say 50B) odino heat-et treated et mairap ya i-welding ya ag-ira man-crack tan naandi so tempered properties da.
