ลวดเชื่อมสแตนเลสไฟฟ้า รุ่น E308L-16 3.2x350mm
Stainless Steel Welding Electrode E308L-16 3.2x350mm SUMO
Feature
-
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
Applications
- Type 302, 304 and 308 stainless steels
- A743 and A744 Type CF-8 cast material
