STAINLESS STEEL FOR FILTER APPLICATIONS.

摘要

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