Brife Introduction:
Alloy structural steel is provided with higher yield strength,
tensile strength, endurance strength, yield ratio (about 0.85
generally ) enough plasticity and toughness.
The concentration of alloy element of this kind of steel is quite
high, mainly are corrosion resistant steel, heat resistant steel,
wear resistant steel, and other special steels of physical and
chemical properties. Alloy structural steel has preferable
mechanical property than that of carbon structural steel, high
performance of heat treatment especially.
The alloy is usually produced by EAF /VD /LF followed by
electroslag refining (ESR) if necessary for special purpose.
Bars and, where applicable, forgings are subjected to ultrasonic
examination based on the different level according to the buyers'
requirements.
Bars are usually supplied bright in the annealed condition.
Final heat treatment - heat treatment / QT
