Duplex steel studs

Duplex steel threaded rods are made of duplex stainless steel, which combines
high strength and corrosion resistance. The most common grades used are 1.4410
(S32750) and 1.4501 (S32760), known as 2507 duplex stainless steel. ‌

Material Properties

Duplex steel has a microstructure that contains both austenite and ferrite
phases, providing better strength than regular stainless steel. It can resist
chloride stress corrosion cracking and pitting, suitable for marine or
industrial environments. ‌

Standard and Threading
