1.1169 is middle carbon manganese base structural steel, S92 Round Bar, flat bar Electroslag melting, Hot Ultrasonic test, Forging, Rolling, Heat treatment, Straightened, Ultrasonic test, Cold machined.
MATERIAL DATA SHEET - Grade DIN 1.1169
MATERIAL CATEGORY: Low temperature steel
PRODUCT DESCRIPTION
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
