310MoLN (725LN)


A-one Alloy supplies high quality 310MoLN  bars.

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
