The invention aims at providing environment-friendly lead-free easy-cutting stainless steel used for a ball-point pen point and a smelting method thereof. The stainless steel is characterized in thatthe stainless steel is ooCr22Mo2BiS stainless steel and comprises the components including, by mass, smaller than or equal to 0.03% of C, smaller than or equal to 2.0% of Mn, smaller than or equal to1.0% of Si, 21.0-23.0% of Cr, 1.0-3.0% of Mo,, smaller than or equal to 0.30% of Ni, 0.15-0.35% of Bi, 0.2-0.4% of S, smaller than or equal to 0.015% of P, smaller than or equal to 0.10% of Pb and thebalance Fe. According to the environment-friendly lead-free easy-cutting stainless steel used for the ball-point pen point, the Bi replaces Pb, an intermediate alloy is adopted for increasing the Bisteady yield, and accordingly, the environment-friendly lead-free easy-cutting stainless steel used for the ball-point pen point is prepared; and the smelting method of the stainless steel is easy, the preparation cost is low, and the smelting method is applicable to large-scale application and production.
