SAW Wire

YL-ENi3

Description: H09MnNiDR is a submerged arc welding wire for 3.5%Ni low-temperature steels. It features low sulfur and phosphorus content and offers good low-temperature toughness. Applications: When paired with fluxes such as GQ216, it is suitable for submerged arc welding of –70 °C low-temperature steels used in pressure vessels for the coal chemical and petrochemical industries, such as H09MnNiDR steel.
