Material Properties

S32750/2507 super duplex stainless steel combines the superior properties of both austenitic and ferritic dual-phase microstructures. Its tensile strength significantly exceeds that of conventional stainless steel. S32750 exhibits exceptional resistance to chloride stress corrosion cracking and outstanding performance against pitting and crevice corrosion. This material performs stably in harsh environments like acidic and alkaline media, making it an ideal alternative to high-alloy austenitic stainless steels. MTSCO's S32750 seamless tubes utilize raw materials sourced from major manufacturers like Baosteel and TSINGSHAN, with secondary PMI testing ensuring 100% accurate material composition.
