Hello,

What is the difference between an EN grade and a EN number?

Grade is a subpart specification in a standard and the number should have been represented as a EN number. Thus, X5CrNi18-10 defines the material grade in terms of the chemical composition and 1.4301 is the EN designation for the material.


X5CrNi18-10 (EN 1.4301) is a Stainless Steel defined under many EN and other standards Other countries standards embrace this material and re-publish under their own standards, e.g. BS (British Standard), DIN, etc.


For example, AISI 304 standard is roughly the same materials as X5CrNi18-10 (EN 1.4301).

Thanks for the answer.

Does it matter if i use X5CrNi18-10 or EN 1.4301? Will it mean the same thing?

[Kelly_Bramble]

I would use both, e.g.

X5CrNi18-10 (EN 1.4301)
