AL-6XN grade routes.

Use the cards to build a shortlist. Final suitability remains an engineering and code decision.

Selection basis

AL-6XN is evaluated when common 300-series stainless grades do not provide the required chloride resistance, while austenitic fabrication characteristics remain desirable. It should be compared with 904L, 254 SMO, duplex, super duplex, and nickel alloys using actual corrosion data and life-cycle cost.

Procurement comparison

Translate the material name into order data.

The same commercial alloy name can map to different forging, fitting, and casting designations. State the complete material and product-form specification.

What is AL-6XN?

AL-6XN is a highly alloyed super-austenitic stainless material identified by UNS N08367. Its nickel, molybdenum, chromium, and nitrogen balance is used to support strength and localized-corrosion resistance in demanding process environments.

How do I choose between the listed AL-6XN grades?

AL-6XN is evaluated when common 300-series stainless grades do not provide the required chloride resistance, while austenitic fabrication characteristics remain desirable. It should be compared with 904L, 254 SMO, duplex, super duplex, and nickel alloys using actual corrosion data and life-cycle cost.

Can the same alloy designation be used for flanges, fittings, and valves?

The same alloy family can be used across a pressure system, but the ASTM grade designation can change with product form and manufacturing route. Confirm the forging, wrought-fitting, or casting specification together with the dimensional standard and pressure rating.

What should a AL-6XN RFQ include?

Include component type, exact grade and UNS where applicable, ASTM product specification, size, schedule or bore, pressure class, facing or end connection, quantity, service conditions, heat treatment, testing, certification, marking, and inspection requirements.

Does the material standard also define flange, fitting, or valve dimensions?

Usually not. The purchase specification normally combines a material standard with a dimensional or pressure-rating standard such as ASME B16.5, B16.9, B16.11, B16.34, an EN or DIN standard, or a project-specific specification.
