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 + LF + VD / EF 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, or bright annealing specially.
Final heat treatment - Quenched and tempered.
PROFILE & DIMENSIONS
Round bar / Disc (diameter): 5.5mm to 800mm
Square bar / Flat bar: 8mm to 600mm
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.
