Solution Annealing	Excellent	–	2.6

APPLICATIONS/ENVIRONMENTS/DESIGN CONSIDERATIONS
Fondinox patented 316LHP is a very good choice in environments that require the same corrosion resistance that is expected by traditional AISI 316L, but offers 50% higher mecanichal strength (300 MPa minimum), so the alloy finds application in high pressure valves bodies and balls for ball-valves.
