welding wire ER317

ER- 317L is suitable for welding of matching chemistry steel used under severe corrosion conditions in petrochemical and paper industry. This grade has higher Molybdenum and Nickel content than ER 316L grade to improve crevice and pitting corrosion resistance. Low carbon content reduces the possibility of intergranular carbide precipitation. This increases the resistance to intergranular corrosion without the use of stabilizers such as Niobium and Titanium. This low carbon alloy, however, may not be as strong at elevated temperature as the niobium stabilized alloys or Type ER 317.
