UNS S46910 combines the characteristics of its stainless-steel family with grade-specific alloying and heat-treatment behavior suited to its intended service.
Strength is developed through solution treatment followed by controlled aging.
Aged conditions can provide much higher strength than annealed austenitic stainless steel.
Provides useful stainless corrosion resistance, with grade-specific differences.
Mechanical properties depend strongly on the selected aging condition.
UNS S46910 is selected for engineered components and bolting where the material characteristics of this grade match the service environment.
UNS S46910 is considered for high-strength bolting when its grade-specific corrosion, strength and temperature characteristics meet the service requirement.
UNS S46910 is considered for aerospace hardware when its grade-specific corrosion, strength and temperature characteristics meet the service requirement.
UNS S46910 is considered for pump and valve components when its grade-specific corrosion, strength and temperature characteristics meet the service requirement.
UNS S46910 is considered for precision mechanical components when its grade-specific corrosion, strength and temperature characteristics meet the service requirement.
Always specify the exact UNS grade and aging condition.
Use condition-specific mechanical and fatigue data for design.
Check galling, hydrogen exposure and corrosion compatibility for threaded applications.
The commonly listed Werkstoff / EN cross-reference for UNS S46910 is 1.4645. Treat this as a grade comparison, not a guarantee of interchangeability. Verify chemistry, product form, condition and governing specification against the supplier certificate before substitution.
