Super Duplex 2507 Fasteners

Super duplex 2507 fasteners specifications

What are Super Duplex 2507 Fasteners?

These trustable components work in petrochemicals, chemical processing, and marine industries. Super duplex 2507 fasteners contain 25% chromium, 7% nickel, molybdenum, and manganese.

We provide multi-sized Alloy 2507 hex bolts, washers, threaded rods, and nuts.


What are the unique properties and characteristics of Super Duplex 2507 fasteners?

The corrosion resistance of super duplex 2507 hex bolts is spectacular, lending them resilience against seawater, brine, chlorides, and inorganic acids.

These weldable products withstand temperatures from -50°C to 300°C. DIN 1.4507 hex nuts also resist intergranular corrosion and carbide precipitation.

What are the advantages of using super duplex 2507 hex bolts and EN 1.4410 nut over other materials? How can they improve the safety and reliability of a project?

An EN 1.4410 nut works reliably in corrosive conditions and extreme temperatures (cryogenic to elevated). Leak-proof, accurate fasteners boost the application’s safety, performance, and service life.

Alloy 2507 washers are very formable. They can perform multiple roles in boilers, desalination plants, and automotive sectors.

What is the tensile strength and the yield strength of alloy 2507 washers and UNS S32750 Heavy Hex Bolt? How are they measured using tensile testing?

A UNS S32750 heavy hex bolt has a tensile rating of 800 Mpa and yield strength of 551 Mpa. Heavy hex bolts are larger than regular ones with more distance across the opposite flats.

Manufacturers must assess the tensile strength of zeron 100 UNS S32760 washers before delivery. The standard procedure (destructive) involves a universal testing machine with grips, a load, and a measuring device. It measures how the fastener handles tensile forces until fracturing.
