What is the difference between 1.4410 and 1.4501?

Both 1.4410 (UNS S32750) and 1.4501 (UNS S32760) are high-performance super duplex stainless steels, but 1.4501 contains added tungsten (W) and copper (Cu), giving it slightly superior corrosion resistance, especially in highly corrosive, high-chloride, or high-temperature environments.

 

Is EN 1.4410 stainless steel bar magnetic?

Yes, EN 1.4410 (a super duplex stainless steel) is magnetic because its structure contains both austenitic and ferritic phases, giving it significant magnetic properties, unlike non-magnetic austenitic stainless steels (such as 304/316).
