What is 1.4403 material
1.4403 is a material grade designation for a type of stainless steel. It is also known as AISI 316 (American Iron and Steel Institute designation) or X2CrNiMo17-12-3 (European Standard designation). This grade of stainless steel is similar to 1.4404 and is also austenitic, meaning it has a face-centered cubic crystal structure.
1.4403 stainless steel is commonly used in various industrial applications such as chemical processing, pharmaceuticals, and food processing. It has good corrosion resistance and is suitable for use in harsh environments.
Some of the key properties of 1.4403 stainless steel include its excellent corrosion resistance, high strength and toughness, and good weldability and formability. It is also resistant to a range of chemicals and acids, making it well-suited for use in harsh environments.
Overall, 1.4403 stainless steel is a versatile and reliable material that is widely used in a range of industrial and commercial applications due to its excellent combination of properties. However, it is less common than 1.4404 stainless steel, which is a more widely used and recognized grade of stainless steel.
The chemical composition of 1.4403 stainless steel (also known as AISI 316 or X2CrNiMo17-12-3) is similar to that of 1.4404 stainless steel. The composition is as follows:
– Carbon (C): 0.07% max
– Silicon (Si): 1.00% max
– Manganese (Mn): 2.00% max
– Phosphorus (P): 0.045% max
– Sulfur (S): 0.030% max
– Chromium (Cr): 16.5-18.5%
– Nickel (Ni): 10-13%
– Molybdenum (Mo): 2-2.5%
– Nitrogen (N): 0.11% max
The addition of molybdenum to the composition of 1.4403 stainless steel provides enhanced corrosion resistance, especially in chloride-containing environments. The high nickel content also contributes to its resistance to corrosion and oxidation.
Overall, the chemical composition of 1.4403 stainless steel gives it excellent properties such as high strength and toughness, good weldability and formability, and resistance to a range of chemicals and acids. It is a versatile and reliable material that is widely used in various industrial and commercial applications.
1.4404 stainless steel (also known as AISI 316L or EN 1.4404) is a versatile material that is widely used in various industrial and commercial applications due to its excellent combination of properties. Here are some other common applications for 1.4404 stainless steel:
