Title:
ALLOY MATERIAL FOR SEALING
Document Type and Number:
Japanese Patent JPH0649599
Kind Code:
A
Abstract:
PURPOSE: To provide a sealing alloy excellent in the acid resistance of oxide film as well as in the adhesive strength between oxide film and alloy as base material by specifying a composition consisting of C, Si, Mn, S, Cr, N, Ti, Al, REM, and Fe.
CONSTITUTION: This alloy is a sealing alloy having a composition consisting of, by weight, 0.005-0.08% C, 0.05-1.0% Sr, 0.10-0.80% Mn, ≤0.008% S, 16-25% Cr, 0.005-0.02% N, 0.15-0.60% Ti, 0.01-0.05% Al, 0.005-0.07% REM, and the balance Fe. This alloy is free from slow leak, increased in supporting strength, and excellent in airtightness, and further, the oxide film after preoxidation treatment is increased in adhesive strength to the alloy and also has superior acid resistance.
