AISI 926 combines the characteristics of its stainless-steel family with grade-specific alloying and heat-treatment behavior suited to its intended service.
High nickel/chromium/molybdenum or strengthening additions provide enhanced service performance.
Molybdenum and nitrogen additions improve resistance to pitting and crevice corrosion in many chloride environments.
Selected for chemical-processing, marine and high-temperature applications.
Mechanical properties depend on product form, heat treatment and specification.
AISI 926 is selected for engineered components and bolting where the material characteristics of this grade match the service environment.
AISI 926 is considered for chemical and process equipment when its grade-specific corrosion, strength and temperature characteristics meet the service requirement.
AISI 926 is considered for marine and offshore hardware when its grade-specific corrosion, strength and temperature characteristics meet the service requirement.
AISI 926 is considered for heat exchangers and piping when its grade-specific corrosion, strength and temperature characteristics meet the service requirement.
AISI 926 is considered for high-performance bolting when its grade-specific corrosion, strength and temperature characteristics meet the service requirement.
Match the alloy to the exact corrosive chemistry and temperature.
Use welded-condition corrosion data where applicable.
For bolting, check galling, preload retention and thermal-expansion compatibility.
The commonly listed Werkstoff / EN cross-reference for AISI 926 is 1.4529. 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.
