Zusammenfassung:	A filter comprising a porous sintered stainless steel is provided. The filter includes 10-30% chromium, 5-25% nickel, 0.5-3% manganese; 1-4% silicon, and 0-3% molybdenum with the remainder being iron and inevitable impurities. The sintered steel has a density less than 80% of full density. The use of a stainless steel powder for the preparation of a filter having improved permeability at high temperatures also is described.
