Arc Welding Service

CATEGORY

TYPE

Solid stainless steel welding wire for submerged arc welding stabilized stainless steels with high Mo content

APPLICATIONS

The alloy is widely used in the chemical and food-processing industries, as well as in shipbuilding. Suitable for welding stabilized corrosion-resistant Cr-Ni-Mo steels for working temperatures up to 400°C.

PROPERTIES

SA 318 is engineered to a very precise analysis to create a weld deposit of high purity, superior hot cracking and corrosion resistance. CVN toughness down to –120 °C, resistant to intergranular corrosion up to +400 °C.
