FAQ
Q1: Antoy pandumaan na 12L14 tan 1215?
A1: Lead (Pb).
Say 12L14 et walay lead to (~0.25%), kanian saya so sankapelesan ya machining steel ya naala.
1215 et anggapoy lead to. Mandedependi labat itan ed asupre parad pakagawa na makina. Mas matantan itan ya gawaen nen say 12L14 balet ta ontutumbok ed RoHS tan ag makaderal ed kaliberliber.
Q2: Nayarin weld so Free Cutting Steel?
A2: Andi. Say atagey ya sulfur tan phosphorus (tan lead ed 12L14) so pansengegan na "hot shortness" tan porosity legan na welding. Sarayan asero et manbitak no i-welding. Adesinyo iratan parad saray parte ya intipon panamegley na saray sinulid odino interference fits, aliwan welding.
Q3: Nayarin napaawet so 12L14?
A3: Aliwan diad panamegley na-panpaawet (pan-erep) lapud abeba so carbon content (<0.15%). However, it can be Case Hardened (Carburized) to improve surface wear resistance while keeping the core soft.
Q4: Akin et importante so cold-drawn finish?
A4: Saray CNC machine tan automatic bar feeders et mankaukolan na saray bar ya diretso tan masimpit so diametro da pian makaandar ya maong ed atagey ya RPM. Saray cold-drawn bars so mangiiter na sayan inkasusto (ISO h9/h10 tolerance) tan walaan met na mas atagey a tensile strength nen saray hot-rolled bars.
