What is SS 2507?

SAF 2507® (UNS S32750) is a super-duplex stainless steel; a high-alloy duplex steel with a PRE value of min. 42*. The grade is characterized by very good chloride corrosion resistance, combined with very high mechanical strength.

What is 6 moly stainless steel?

6% Moly Alloys are often found to have high levels of chromium and nitrogen which makes it even be able to withstand corrosion and stress cracking. They are part of the austenitic steel group which is one of the most widely used grade of stainless steel and is known for its good formability and resistance to corrosion.

What is the purpose of duplex stainless steel?

Duplex stainless steels have roughly twice the strength compared to austenitic stainless steels and also improved resistance to localized corrosion, particularly pitting, crevice corrosion, and stress corrosion cracking. Moreover, they have improved toughness and ductility compared to ferritic SS.

What is martensitic stainless steel used for?

Martensitic steels are very useful in automotive applications for door beams, bumpers, very lightweight and high strength lower side members (rocker panels), and cross car bars and beams that are designed to prevent intrusion into the passenger compartment.

What is super austenitic stainless steel?

Superaustenitic stainless steels are defined as austenitic, iron-based alloys that have pitting resistance number (PREN) greater than 40.
