What Is 1.4404 Grade Equivalent To?
1.4404 is the EN 10088-1 designation for AISI 316L, a widely used stainless steel known for its excellent corrosion resistance and weldability. It contains 2.0–2.5% molybdenum, which improves its pitting resistance compared to 304 stainless steel.
What is the equivalent material for 1.4435 stainless steel?
1.4435 stainless steel, also known as X2CrNiMo18-14-3, is equivalent to AISI 316L (or sometimes referred to as 316LMo). It's an austenitic stainless steel with a higher molybdenum content than standard 316L, giving it enhanced corrosion resistance, particularly in chloride-containing environments

Corrosion Resistance
Both 1.4404 and 1.4435 offer excellent corrosion resistance, especially in chloride-rich environments (e.g., marine and chemical industries). 1.4435 offers better pitting resistance due to its lower phosphorus (P) and sulfur (S) contents, but the difference between the two is minimal in most applications.
Machinability
1.4435 is easier to machine than 1.4404 due to its extremely low sulfur content (≤0.010%), which improves chip breaking and extends tool life.
What is the difference between 1.4404 and 1.4432?
EN 1.4404 and 1.4432/1.4436 have a versatile corrosion resistance and are suitable for a wide range of applications. The grades with higher molybdenium content ( 1.4432,1.4436) have somewhat enhanced corrosion resistance compared with grades with lower Molybdenium content (1.4404).
