摘要（英）：

The invention provides stainless steel, a stainless steel wire for the pen point of a ball-point pen, a preparation method of the stainless steel, and a preparation method of the stainless steel wire. The stainless steel comprises the following components in percentage by weight: 0.03% or less of C, 0.20-0.50% of Si, 0.90-1.50% of Mn, 0.050% or less of P, 0.20-0.40% of S, 19.0-21.0% of Cr, 1.50-2.50% of Mo, 0.030% or less of N, 0.10-0.30% of Pb, 0.01-0.07% of Te, 0.05-0.30% of V, 0.01-0.50% of Nb, 0.10-0.50% of Ni, 0.10-0.50% of Cu, 0.005-0.020% of O, and the balance of Fe and inevitable impurities. The preparation method of the stainless steel comprises the following steps of: performing primary smelting; performing refining; and performing continuous casting. The preparation method of the stainless steel wire comprises the following steps of: performing primary smelting; performing refining; performing continuous casting; performing heating for the first time; performing rolling for the first time; performing surface treatment; performing heating for the second time; and performing rolling for the second time.
