PURPOSE:To improve the deep drawing property and burring workability in the titled member by using the material containing Cr, Ni, C, Mn, Si, Al, Mo, O, S and Fe of the specified wt% and inevitable impurity as said member. CONSTITUTION:Stainless steel containing Cr of 15-17wt%, Ni of 13-15wt%, C of 0.1wt% or less, Mn of 0.005-2.5wt%, Si of 0.0051.0wt%, Al of 0.005-0.2wt%, Mo of 2.0wt% or less, O of 0.003wt% or less, S of 0.003wt% or less and inevitable impurity is obtained by the vacuum melting method. Therefore, the deep drawing property and burring workability are improved so that it is possible to obtain the optimum member for the electrode of the electron gun.
