2507 is a super duplex stainless steel with higher alloy content, thus making it superior to 2205 in corrosion resistance and strength. It has excellent resistance to uniform, pitting, crevice corrosion and chloride stress corrosion cracking.
In dilute sulfuric acid contaminated with chloride ions, 2507 has better corrosion resistance than 904L, which is specially designed to resist pure sulfuric acid. Because 2507’s low carbon content greatly lowers the risk of carbide precipitation at the grain boundaries during heat treatment, it is highly resistant to carbide-related inter granular corrosion.
2507 is not suitable for Applications which require long exposure to temperatures above 300℃ because of the increased risk of a reduction in toughness. Its yield strength is about twice that of conventional austenitic stainless steels.
