ER312 Stainless Steel Welding Wire
Product Name: ER312 Stainless Steel Welding Wire
Application: For welding of dissimilar steels, the crack sensitivity is low, so welding of steel materials such as cladding steel and stainless steel lining is difficult or prone to pores
Product Advantages
ER312 Stainless Steel Welding Wire performs well in harsh environments and high temperature conditions due to its excellent corrosion resistance and crack resistance. At the same time, its wide process adaptability and high-quality welding effect ensure the smooth welding process and high-quality welds, thereby extending the service life of the equipment and improving the overall performance.
Corrosion resistance
ER312 welding wire has good corrosion resistance and can resist corrosion by sulfuric acid, sulfurous acid and organic acids. This allows the weld to maintain good performance in harsh environments and extend the service life of the equipment.
Crack resistance
Due to its ultra-low carbon content and high molybdenum content,Stainless steel welding wire can prevent intergranular corrosion, no heat treatment is required after welding, and high high temperature strength. This allows the weld to maintain good performance in high temperature environments and reduce the occurrence of cracks.
Adaptability
Stainless steel welding wire is suitable for a variety of welding processes, including argon arc welding (TIG), gas shielded welding (MIG), etc. This allows the welding wire to perform well in different welding occasions and improve the flexibility of welding.
Welding quality
ER312 welding wire has good arc stability and weld bead beauty, and the weld is well formed after welding. This makes the welding process smoother, the weld quality is higher, and the occurrence of welding defects is reduced.
Product Features
Chemical composition
The chemical composition of stainless steel welding wire mainly includes carbon (C) ≤ 0.12%, manganese (Mn) 1.00-2.00%, silicon (Si) ≤ 0.90%, chromium (Cr) 11.50-13.50%, nickel (Ni) 8.50-10.50%, and molybdenum (Mo) 0.75-1.25%.These ingredients give the welding wire good corrosion resistance and high temperature strength.
