Chemical Composition (Typical Values):

•     Carbon (C): ≤ 0.03% – Low carbon for corrosion resistance
•     Silicon (Si): ~0.90% – High silicon improves fluidity and bead appearance
•     Manganese (Mn): ~1.80% – Supports arc stability and weld pool control
•     Chromium (Cr): 18.0–20.0% – Provides corrosion and oxidation resistance
•     Nickel (Ni): 11.0–14.0% – Enhances ductility and toughness
•     Molybdenum (Mo): 2.0–3.0% – Improves resistance to pitting and crevice corrosion
•     Phosphorus (P): ≤ 0.04% – Controlled to prevent embrittlement
•     Sulfur (S): ≤ 0.03% – Controlled to prevent hot cracking
•     Copper (Cu): ≤ 0.75% – May improve corrosion resistance
•     Iron (Fe): Balance – Forms the matrix of the weld deposit
