RAM MATERIAL SPECIFICATION - Grade W-Nr 1.8522
MATERIAL CATEGORY: Carburized structural steel
PRODUCT DESCRIPTION
Simplified design for bolting configuration compared with martensitic steels or high nickel alloys.
Simplified design for bolting configuration compared with martensitic steels or high nickel alloys.
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, or bright annealing specially.
Final heat treatment - heat treatment / QT
