EN 1.4113, ASTM 434 / UNS S43400 Stainless Steel

General Characteristics

434/4113 is a 1% molybdenum-alloyed ferritic stainless steel with medium chromium and normal carbon content, which can be used in many corrosive environments, such as at the cold end of automotive exhaust systems. After tensile elongation, 434/4113 may be prone to the ridging-surface phenomenon.
