Abstract
The present invention provides a material which is superior in all of peel resistance, corrosion resistance and abrasion resistance against alcoholic fuels. The material comprises an Fe-Cr-C based steel or Fe-Cr-C-Cu based steel. For applications wherein members formed from the material are subjected to impacts, the Cr content is within the range of at least 8.0% and less than 16.0%, the relation between the C content and the Cr content satisfies % Cr+25.times.% C.ltoreq.32 based on weight, and the ratio of the area of a primary carbide to the total sectional area of the material is 1.5% or less. For non-impact applications Cr content is more than 12.0% and less than 16.0%, % C and % Cr satisfy % Cr+25.times.% C>32, and the ratio of the area of a primary carbide to the total sectional area of the material is 8.0% or less. This material is especially superior in peel resistance against alcoholic fuels. The Fe-Cr-C based steel may optionally contain Cu, Si, Mn, W, Mo, V, Co, and Ni.
