Frequently Asked Questions (FAQs)

What is the difference between 317L and 317LN?

317LN is similar to 317L but with added nitrogen content that enhances yield strength and improves resistance to pitting and crevice corrosion in chloride-rich environments.

Do you provide MTC and TPI for Alloy 317LN?

Yes. All our Alloy 317LN products are supplied with Mill Test Certificates (EN 10204 3.1/3.2) and can be inspected by third-party agencies like SGS, TUV, or BV.

Can Alloy 317LN be used in food and pharma industries?

Yes, its low carbon content, non-toxic composition, and excellent corrosion resistance make it suitable for hygienic and clean-room environments.
