PROBLEM TO BE SOLVED: To produce a stainless steel for a gas burner stably workable without generatingαfracture in high speed continuous pressing and excellent in durability. SOLUTION: This steel is the one having a compsn. contg., by mass, 0.07% C, 1.0 to 2.5% Si, <=5.0% Mn, 5.0 to 9.0% Ni, 14.0 to 19.0% Cr, <=4.0% Cu, <=0.10% N, <=0.0030% S and <=1.0% Mo (including the case of no addition), in which the relation in which (a) value in accordance with the following formula is maintained to the range of -0.30 to 1.00 is valid among the above components, and the balance Fe with inevitable impurities: (a) value = 19.43-10.8C-0.14Si-0.54Mn-1.02Ni-0.57Cr-0.49Cu-7.53N.
