Standards and designations

Magnadur 601 is a non-standard special steel
 

Special Properties

Nonmagnetic alloy µr  < 1.01 in combina-   tion with high strength and high corrosion resistance.
 

Corrosion Resistance

(PREN  = 29.5 - 35)
Magnadur 601 has an excellent resistance against stress corrosion cracking as far as tensile stresses are lower than 0.5 x yield   strength. The pitting corrosion potential is  far better than the potential of Magnadur 501. Although the PREN values of Magnadur 509 and 601 are in the same approximate range, Magnadur 601 is performing better with regard to pitting corrosion due  to higher molybdenum content.
