| Product | AWS | JIS | EN | Description |
| KS-307 | A 5.4 / E307-16 | ES307-16 | E189MnMoR | It is suitable for welding thick plate, rigid joints, and 14% high Manganese steel, armor steel and hard-to-weld steel. |
| KS-308 | A 5.4 / E308-16 | ES308-16 | E199R | It is suitable for welding AISI 301,302,304 and 305 stainless steel. |
| KS-308H | A 5.4 / E308H-16 | ES308H-16 | E199HR | For high carbon 18CR-8Ni stainless steel. |
| KS-308L | A 5.4 / E308L-16 | ES308L-16 | E199LR | It is suitable for welding 18%Cr-8%Ni steel (AISI 304,304L) and 19.5%Cr-10Ni steel (AISI 347). |
| KS-308LT | A 5.4 / E308L-16 | ES308L-16 | E199LR | It is ideal for welding chemical equipment, vessels and pipes of liquid helium, liquid hydrogen, liquid nitrogen and liquid natural gas. It has excellent impact properties at low temperature. It is also suitable for applications which require low magnetism. |
| KS-308EL | A 5.4 / E308L-16 | ES308L-16 | E199LR | It provides excellent weldability, easy slag removal and smooth beads. It has better corrosion resistance than KS-308L due to extra low carbon content. It is suitable for welding low carbon 18%Cr-8%Ni steel, such as AISI 304L. It is also suitable for applications which require low magnetism. |
| KS-309 | A 5.4 / E309-16 | ES309-16 | E2212R | It is suitable for welding AISI 309S and dissimilar metals (mild steel and stainless steel). It is used as the buttering layer when welding dissimilar metals, which provides excellent performance for corrosion resistant surface between mild steel and hard-to-weld steel |
| KS-309L | A 5.4 / E309L-16 | ES309L-16 | E2212LR | Weld metal is low carbon with 24%Cr-13%Ni. It provides excellent crack resistance due to low carbon and more ferrite. It is suitable for welding low carbon stainless steel and low carbon cladding, AISI 309S, heat resistant steel (13Cr, 18Cr steel) or dissimilar metals. |
| KS-309Mo | A 5.4 / E309Mo-16 | ES309Mo-16 | — | It provides better strength, crack and corrosion resistance than KS-309 at high temperature due to additional Mo content. It is suitable for welding dissimilar metals (carbon steel and low carbon stainless steel), such as carbon steel and AISI 316. |
| KS-309MoL | A 5.4 / E309LMo-16 | ES309LMo-16 | E23122LR | It provides better corrosion than KS-309Mo due to low carbon content. It is suitable for welding dissimilar metals (carbon steel and low carbon stainless steel), such as carbon steel and AISI 316L. |
