Caliper Overseas is a reliable Super Duplex Steel S32950 Fasteners manufacturer and supplier in India, that provides fasteners with high performance to meet challenging applications. Super Duplex Steel UNS S32950 fasteners are known for their superior strength, better corrosion resistance and durability. Due to the high chromium (25%), molybdenum (4%), nickel (7%), and nitrogen content in the composition, these fasteners are resistant to pitting, crevice corrosion, and stress corrosion cracking. The dual-phase microstructure of ferrite and austenite ensures high toughness and strength while maintaining good ductility and weldability; hence, they are perfectly suitable for offshore marine applications as well as the chemical processing industry.
Our fasteners are made according to international standards like ASTM A479 and ASME SA479, and come in sizes from M3 to M90 and lengths from 10mm to 1000mm. We provide safe packaging and fast delivery all over India. For long-lasting, high-strength fasteners, contact us today and find the perfect fit for your industrial requirements.
