Description

1.4306 / AISI 304 L is an austenitic chromium-nickel stainless steel with a low carbon content.

Special properties

1.4306 is essentially a more highly alloyed version of 1.4307. Due to the slightly higher chromium and notably higher nickel content, 1.4306 is more corrosion resistant than 1.4307.
