FIELD: technological processes. ^ SUBSTANCE: present invention relates to filter comprising porous sintered stainless steel. Filter comprises 10-30% of chrome, 5-25% of nickel, 0.5-3% of manganese, 1-4% of silicon, 0-3% of molybdenum, the rest is iron and unavoidable admixtures. Sintered steel has density less than 80% of full density. ^ EFFECT: use of proposed powder of stainless steel to make filter provides for improved permeability at high temperatures. ^ 6 cl, 2 tbl, 2 ex, 1 dwg |
