ลวดเชื่อมไฟฟ้าเหล็กแข็ง SUMO E7016 2.6x350mm
LOW HYDROGEN ELECTRODE SUMO E7016 2.6x350mm
Features & Applications
E308L-16 is used for welding stainless steel structures that fabricated by 022Cr19Ni10 or 06Cr18Ni11 Ti (e.g. 304L or 308L) stainless steel, which work temperature lower than 300, such as facilities of synthetic fibre, fertilizer, petrochemical equipment and so on. The weld metal has good resistance to intercry stalline corrosion
