Pian magmaliw ya awtoridad so pahina, makatulong so pangipanengneng ed mismon proseso. Say kaslakan a rota parad sarayan atagey-biskeg a malimpek a bar et onia:

a) Panaggawa na asero tan segundaryon panagpino
Say asero et natunaw ed BOF o EAF, insan i-treat ed LF/VD pian naekal so asupre tan phosphorus tan pian na-adjust so alloy content. Ditan so pangiyarum ed saray micro-alloying elements a singa say V, Ti tan B. Say abeban P tan S ed MTC yo (0.015–0.017% P, 0.003–0.004% S) et eksakton resulta na sayan kundang - napaaligwas da so inka-tough tan weldability.

b) Say panag-cast tan panagparaan na billet
Say pinarakep ya asero et ipelag ed saray billet ya matukoy parad panag-roll na malimpek a bar. Saray malinis ya billet ya abeba so inlaktip to et importante pian makapasa ed bend/rebend tan impact tests ya nanengneng ed sertipiko yo.
