Product Introduction

1.4466 Stainless Steel Material Supplier Manufacturer, Contact us to get UNS S31050 Material price list, Sizes & Free Sample!

AISI 310 MoLN is a 310L modified austenitic stainless steel with low carbon, low silicon and high nitrogen additions. 1.4466 Material has excellent corrosion resistance in ammonium carbamate and nitric acid. It is more resistant to crevice corrosion, stress corrosion cracking (SCC) than ASTM 316L due to the high chromium, molybdenum and nitrogen content (PREN > 33). UREA 25.22.2 can be designed for urea plant lining or supporting products (pipes, steel plates, round bars, accessories...).

HT PIPE is a well-known stockist and exporter. We are a 1.4466 Material supplier with 15+ export experience. We not only provide pipe, 310MoLN Stainless Steel Plate, round bars, but also pipe fittings, flanges, etc. Contact us for more information and prices for free.

Why 310MoLN is Essential for Urea Plants

In urea synthesis, equipment is exposed to high-pressure ammonium carbamate, which is extremely corrosive. 310MoLN is the preferred material for:

Urea Strippers: High resistance to heat and carbamate erosion.
Condensers & Scrubbers: Proven longevity in severe chemical cycles.
Nitric Acid Equipment: Superior to standard 310S or 316L in highly oxidizing media.
