Put these details in one RFQ to streamline grade, finishing and logistics confirmation.
Specify both the alloy grade and operating conditions for your equipment procurement.
316L has a specified carbon maximum of 0.030%. The lower carbon level helps reduce sensitization in welded heat-affected areas and supports corrosion-resistant fabricated equipment under suitable service conditions.
Share the weld design, fabrication route and service environment when requesting your plate grade.
The molybdenum-bearing alloy composition helps improve resistance to localized corrosion compared with conventional chromium–nickel austenitic grades in many relevant environments.
Confirm process medium, chloride concentration, operating temperature and cleaning conditions with your engineering specification.
