Frequently asked questions about 1.4307
What is the difference between 1.4301 and 1.4307?
1.4307 (304L) has less carbon (≤ 0.03 %) and is therefore more weldable and more resistant to intergranular corrosion.
When to use 1.4307 instead of 1.4301?
Above all for welded parts where intergranular corrosion must be avoided.
