BLACK 605M36T

Description

A commonly used general purpose steel used for a wide range of engineering parts. It is capable of being heat treated to produce a wide range of tensile strengths combined with good ductility and resistance to shock. It has excellent hardenability, enabling it to be used for medium tensile strengths it has freedom from temper brittleness and has good ductility and shock resistance The bars are often supplied in the hardened and tempered condition with a tensile strength range of 850-1000 N/mm². Material is readily machinable so that the components can be put into service without the cost of further treatment. Bars can also be supplied in the softened state which require hardening and tempering but give increased machinability.
