What Is X12CrNi23-13 / 1.4833 / 309S Stainless Steel?
X12CrNi23-13 (material number 1.4833) is the European designation for AISI 309S, a heat-resistant austenitic stainless steel designed for elevated temperature service and oxidation resistance. It contains high levels of chromium (~23%) and nickel (~13%), making it suitable for furnace parts, heat treatment equipment, and high-temperature ducts.
This grade is used in industries such as metallurgy, petrochemicals, power plants, and thermal processing.
