WHAT IS 1.4462?
The alloy of austenite and ferrite makes a form of stainless steel (SS) called Duplex. This is also known by working material number 1.4462. There are a number of advantages of work material number 1.4462 in bolts over standard stainless steel:
- It can handle higher tensile strength as standard stainless steel.
- In addition, these bolts offer better resistance to localized corrosion compared to standard stainless steels.
- A higher PREN value to prevent pitting corrosion.
Although there are some alternatives with equivalent characteristics to 1.4462 bolts, this work material number has less cost in production making its use very cost-effective.
