Stainless Steel 410S Seamless Pipes & Tubes

Stainless Steel 410S seamless pipes and tubes (UNS S41008, EN 1.4000) are a lower carbon version of 410, containing 11.5% to 13.5% chromium. With carbon limited to 0.08%, the grade stays softer and more ductile after welding, making it easier to fabricate than standard 410. It is a useful choice for applications that need the corrosion and heat resistance of a chromium stainless steel without excessive hardening around welded areas. Amardeep Steel supplies SS 410S seamless pipes and tubes with EN 10204 3.1 mill test certificates, heat treatment records and complete heat traceability.

What Are Stainless Steel 410S Seamless Pipes & Tubes?

Grade 410S is a ferritic, non hardening 12% chromium stainless steel. It resists oxidation and mild corrosion, and its low carbon means it does not form hard martensite in the weld zone, so welded parts stay ductile without post weld heat treatment.

410S vs 410: Why the "S" Matters

Standard 410 allows up to 0.15% carbon and hardens on cooling, which makes it strong but brittle near welds. 410S cuts carbon to 0.08% maximum and limits nickel, so it stays soft. Choose 410 when you need hardness; choose 410S when you weld the part or need formability.

Applications of SS 410S Seamless Pipes and Tubes

• Refinery and petrochemical trays and liners
• Heat treatment and annealing boxes
• Oxidation resistant furnace parts
• Welded assemblies that need ductile weld zones

Testing and Documentation

Every order of SS 410S seamless tube goes through the checks below at our testing facility or approved third party labs.

• Chemical analysis and PMI
• Tension test
• Flattening and flaring tests
• Hardness test
• Hydrostatic test on request
• Ultrasonic or eddy current testing on request
• Visual and dimensional inspection

Mill test certificates are issued to EN 10204 3.1, with 3.2 available on request. You can view our approvals on the certificates page.

Packing and Marking

Each length is marked with grade, size, heat number and heat treatment condition. Ends are capped. Tubes are packed in bundles or wooden boxes for export. Read more about our packing and despatch process.
