AISI 304L Stainless Steel
304L is the low-carbon version of 304, selected to reduce sensitization risk during welding and fabrication.
Grade overview
Lower carbon limits improve resistance to chromium-carbide precipitation in welded sections under relevant thermal exposure.
Typical applications
Welded tanks, piping, process equipment, food/pharma fabrication and general corrosion-resistant assemblies.
Equivalent / related designations
Commonly associated with EN 1.4307/1.4306 families depending on specification. Dual-certified 304/304L products are common in some forms.
Common manufacturers and supply
Available from most major global stainless producers.
Fabrication and selection notes
Confirm the exact product standard, edition, dimensions, delivery condition, mechanical properties, impact requirements, heat treatment, welding procedure, corrosion environment and certification. A grade name alone is not sufficient for procurement or design approval.
QA/QC documentation
For critical service, verify heat number traceability, mill test certificate, chemical analysis, tensile/impact results where required, NDT, heat-treatment record and project-specific third-party inspection requirements.
Element Folio engineering reference. Values and requirements vary by standard edition, product form and manufacturer; always verify the latest governing specification.
