Thread Content

Type 317 stainless steel is suitable for applications that require a longer service life than that of type 316. Due to slightly higher contents of Cr, Mo, and Ni elements compared to type 316, it exhibits better resistance to crevice corrosion, pitting, and stress corrosion. AISI 904L or SUS 890L stainless steel is a cost-effective austenitic stainless steel that balances price and corrosion resistance; it offers better corrosion resistance than the aforementioned materials, making it particularly suitable for use in acids such as sulfuric acid and phosphoric acid, as well as halides (containing Cl— and F—). Due to its high contents of Cr, Ni, and Mo, it exhibits excellent resistance to stress corrosion, pitting, and crevice corrosion.
