6150 SUP10 51CrV4 1.8159 Hot Forged Rolled Steel Round Bar
1: 6150 steel introduction
AISI 6150 steel is chromium vanadium type spring steel. It's a similar alloy steel to 5150 steel with small, but effective, vanadium addition, to import greater hardness. AISI steel 6150 has low distortion properties and is easily heat treated. The SAE 6150 steel grade is suitable for oil hardening and tempering

| Application | 6150 spring steels are used for heavily stressed machinery parts including shafts, gears, pinions and also in hand tool components. ASTM 6150 steel is also widely in the motor vehicle industry AISI 6150 is suitable for many general engineering applications that require high tensile strength and toughness | |
6: Delivery condition
For hot rolled bar, usually the delivery condition is hot rolled, annealed, Black surface.
For hot rolled sheet, usually the delivery conditon is hot rolled, annealed, black surface.
SUP10 has the dual advantages of high strength and high toughness. Its tensile strength is up to 1200MPa, can withstand extremely high tensile stress, and its elongation at break is also very good. This combination of high strength and toughness makes SUP10 adaptable to a variety of complex operating conditions.
SUP10 has good wear resistance. Its hardness can reach 50-60HRC, enough to resist strong wear and shear forces. This superior wear resistance makes SUP10 commonly used in parts requiring long lasting durability, such as mechanical springs, contact springs, damping springs, chimneys, coal mining machinery, etc. SUP10 has excellent corrosion and oxidation resistance. Due to its excellent combination of chemical components, SUP10 is excellent in corrosion under harsh environments such as hard water, salt water, acid and alkaline. At the same time, it can also work stably at high temperature for a long time, so SUP10 is widely used in the fields involving high temperature and corrosion, such as pipes, high temperature furnaces, engines and other high temperature industrial fields.
SUP10 has good plasticity, workability and weldability. In the production process, SUP10 can be cold machining, hot machining, forging, rolling and other processing methods using a variety of conventional processes. In addition, SUP10 can be welded with other materials if proper welding methods are used.
