PRODUCT DESCRIPTION
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 in the annealed, peeled bright condition.
Final heat treatment - Quenched and tempered.
PRODUCT PROFILE & DIMENSIONS
Round bar / Disc (diameter): 5.5mm to 850mm
Square bar / Flat bar: 6mm to 650mm
Plate / Steel strip: 1.0mm to 200mm
Steel sheet: thickness 1.0 ~ 4.0mm, width 10 ~ 1000mm X length 1000/2000mm - Standard size
Length: random length or based on the customer's special requirement
Forged steel shape: stepped shafts, other different shapes based on OEM.
