Four stages, in order
The sequence is what gives the bar a hard surface and a ductile core. Skip a stage and you get a bar that either snaps or bends.
Hot rolling
Billets are rolled down to the finished diameter at around 1,000 °C and leave the last stand still glowing.
Quenching
The bar passes through a high-pressure water jacket. The outer skin hardens into martensite in a fraction of a second while the core stays hot.
Self-tempering
Heat trapped in the core flows back outward and tempers that hardened rim into tough tempered martensite.
Atmospheric cooling
On the cooling bed the core transforms slowly into ductile ferrite and pearlite. Hard outside, soft inside — that is the whole trick.
