Quick Details
1: F11 steel introduction
F11 has high thermal strength, oxidation resistance and hydrogen corrosion resistance at high temperature. Due to the high content of Cr, C and other alloying elements in the steel, the hardening tendency of the steel is obvious and the weldability is poor. Due to the addition of Cr, Mo and other alloying elements into the low carbon steel, the comprehensive properties of the steel are greatly improved. Such as good high temperature mechanical properties, high temperature oxidation resistance, corrosion resistance, good toughness, process properties and weldability.

4: F11 steel mechanical properties
The mechanical properties mainly include tensile strength, yield strength, elongation, area or reduction, hardness, impact value, non-metalic inclusion etc. Different heat treatment, the mechanical properties will be different, such as normalized, tempered, QT. If you want to know the properties, kindly contact the salesman.

6: Heat Treatment
Heat treatment temperatures, rate of heating, cooling and soaking times will vary due to factors such as the shape and size of each component. Other considerations during the heat treatment process include the type of furnace, the quenching medium and work piece transfer facilities. Please consult a heat treatment specialist for full guidance on heat treatment.
7: Delivery condition
For hot forged bar, usually the delivery condition is hot forged, annealed/QT, rough turned/Black surface.
For hot rolled bar, usually the delivery condition is hot rolled, annealed/QT, Black surface.
For hot forged block, usually the delivery condition is hot forged, annealed/QT, milled surface/Black surface
For hot rolled plate, usually the delivery condition is hot rolled, annealed/QT, black surface.
For cold drawn bar, usually the delivery condition is cold drawn, annealed/QT, peeled/black surface
