Chemical Composition (Typical Values):

•     Carbon (C): ≤ 0.15% – Controlled to reduce cracking
•     Chromium (Cr): 28.0–32.0% – High corrosion and oxidation resistance
•     Nickel (Ni): ~8.0–10.0% – Enhances ductility and toughness
•     Manganese (Mn): 0.5–2.5% – Supports arc stability and weld pool control
•     Silicon (Si): ~0.90% – Aids slag formation and arc performance
•     Molybdenum (Mo): ≤ 0.75% – Optional trace for added corrosion resistance
•     Phosphorus (P): ≤ 0.04% – Controlled to prevent brittleness
•     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
