310MoLN 725LN Urea Grade S31050 Ss Round Bars Ultra 725LN EN 1.4466 ASTM UNS S31050

Introduction

A-one Alloy supplies high quality 310MoLN bars and pipes.

Stainless steel grade 310MoLN is a fully austenitic stainless steel that does not have intermetallic phases such as intergranular carbide precipitations. The 310MoLN steel grade has an optimized chemical composition designed specifically for applications in urea plants. The nitrogen in the chemical composition helps to stabilize and strengthen the austenitic phase. This material provides improved corrosion-resistance in urea carbamate environments such as high-pressure strippers.

Density: 7.9g/cm3

Character

• Very good corrosion resistance to carbamide synthesis.
• Good corrosion resistance to intergranular corrosion.

Application

Production of carbamide.
