PLX is the name Fixe has given to the well-known Duplex 2205 stainless steel. This material has a two-phase micro-structure of ferritic steel and austenitic stainless steel. PLX arises from the combination of the two materials.
PLX has some outstanding properties:
- Strength. PLX is nearly twice as strong as austenitic stainless steel.
- Corrosion-resistance. PLX has ranges of resistance to common corrosion that are slightly higher than those of A4 (316) stainless steel.
- Resistance to stress corrosion cracking (SCC). PLX, due to its two-phase micro-structure, provides greater resistance to SCC. Stress corrosion cracking may result in sudden breakage with common austenitic steels (A2 and A4).
