ABSTRACT:
A high Young's modulus material comprises carbon steel or alloying steel and contains a particular amount of hard particles having a Young's modulus of not less than 24,000 kgf/mm.sup.2. Furthermore, a surface-coated tool member comprises a substrate comprised of carbon steel or alloying steel and a hard coating layer having a Young's modulus of not less than 24,000 kgf/mm.sup.2 in which the substrate contains a particular amount of hard particles having a Young's modulus of not less than 24,000 kgf/mm.sup.2.
