20MNV6 BS4360 GR Alloy Steel Seamless Pipes High Yield With Ferritic Pearlitic Steel

Name : 20MNV6/280X Alloy seamless Steel Pipes with high yield and tensile strength due to the micro alloying effect

Principal application fields :

Ferritic pearlitic steel:

20MnV6 is a carbon-manganese steel micro alloyed with vanadium, characterized by excellent machinability and weldability with high yield and tensile strength due to the micro alloying effect of the vanadium. The low carbon content and the vanadium addition allows surface hardening by carburizing or nitriding. It will also respond to induction hardening with moderate improvement in tensile and yield strength.

20MnV6 is used extensively by all industry sectors for a wide range of applications utilizing its considerable machinability.

Typical applications are: Chrome plating, cylinders, conveyor rolls, hollow shafts, nuts, rings.
