ASTM 430 - EN 1.4016 offers resistance to corrosion, due to its 16% chromium content, and is highly versatile in formability; these features make it a go-to option in wet or indoor settings.
430 stainless steel is a ferritic stainless steel, primarily composed of iron, chromium (approximately 17-18%), and small amounts of nickel, silicon, and carbon. The "430" in its name refers to its main chemical composition, namely 17% chromium and 0.12% carbon.This type of stainless steel typically contains lower nickel content, usually between 4-6%.
430 stainless steel is a general steel type with good corrosion resistance. It has better thermal conductivity than austenite, smaller thermal expansion coefficient than austenite, and is resistant to thermal fatigue. Titanium is added as a stabilizing element. It has good mechanical properties in the weld area and is suitable for general use. In the environment of atmosphere, water vapor, water and many chemical media. It is commonly used in the manufacture of household appliances, kitchen equipment, automotive parts, and construction materials, among others.
430 stainless steel contains a high chromium content. Chromium can chemically react with oxygen in the air, forming a dense layer of chromium oxide (Cr2O3) on the surface, preventing further oxidation reactions. The formed chromium oxide layer has high stability and is not easily destroyed, effectively resisting the erosion of oxygen, water, and other oxidizing agents. 430 stainless steel can effectively resist oxidation corrosion and surface rusting.
430 stainless steel has good corrosion resistance, but in some specific environments, such as high-temperature chloride environments or during welding processes, intergranular corrosion may occur, leading to damage to the material's grain boundaries, reducing its corrosion resistance, and mechanical properties.
