405 vs 410L
These two grades are listed as equivalents of each other: their chemistry windows overlap and they serve the same applications. They are not always identical — check the differences below before substituting, especially in certified designs.
405
Stainless Steel
405 is an aluminium-bearing ferritic stainless designed to remain non-hardening when cooled from welding temperatures, unlike plain 410. It gives 12% chromium corrosion resistance in a weldable, low-cost sheet and plate grade.
Standards: DIN 1.4002 · AISI 405 · JIS SUS405 · GB 06Cr13Al
410L
Stainless Steel
410L is a low-carbon 12% chromium ferritic stainless: reducing carbon below 0.03% keeps it soft, weldable and free of the hardening seen in 410. It is a workhorse for containers, transport and structural applications in mildly corrosive environments.
