Chemical Composition of Stainless Steel Grades
At Vandan Overseas, we provide premium-quality stainless steel materials that comply with global industrial standards. The chemical composition of stainless steel determines its corrosion resistance, mechanical strength, heat resistance, and long-term durability across demanding industrial environments.
Carbon (C)
Carbon controls the strength and hardness of stainless steel. Lower carbon levels improve corrosion resistance and weldability.
Chromium (Cr)
Chromium forms a protective oxide layer that gives stainless steel its excellent corrosion resistance.
Nickel (Ni)
Nickel enhances toughness, ductility, and corrosion resistance, making stainless steel suitable for extreme environments.
Molybdenum (Mo)
Molybdenum improves resistance to pitting corrosion and high-temperature oxidation.
Nitrogen (N)
Nitrogen increases strength and improves corrosion resistance in austenitic stainless steel grades.
