What’s 1.4404 Material?

1.4404 is a material grade designation for a type of stainless steel.

It is also known as AISI 316L (American Iron and Steel Institute designation) or EN 1.4404 (European Standard designation). This grade of stainless steel contains molybdenum, which makes it more resistant to corrosion than other grades of stainless steel.

1.4404 stainless steel is commonly used in various industrial applications such as chemical processing, pharmaceuticals, and food processing. It is also used in the construction of medical implants, as well as in marine environments where it is exposed to saltwater.

Some of the key properties of 1.4404 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, 1.4404 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.

The chemical composition of 1.4404 stainless steel (also known as AISI 316L or EN 1.4404) is as follows:

– Carbon (C): 0.03% 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 1.4404 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 1.4404 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.

The cost of 1.4404 stainless steel can vary depending on factors such as the market demand, availability of raw materials, and manufacturing processes. However, in general, 1.4404 stainless steel is considered to be a more expensive grade of stainless steel compared to some other grades.

For example, 1.4301 (also known as AISI 304 or EN 1.4301) is a commonly used grade of stainless steel that is less expensive than 1.4404 stainless steel. 1.4301 stainless steel also has good corrosion resistance and is suitable for many applications, although it may not be as resistant to certain types of corrosion as 1.4404 stainless steel.

On the other hand, there are some grades of stainless steel that are more expensive than 1.4404 stainless steel due to their specific properties or unique manufacturing processes. For example, superaustenitic stainless steel grades such as AL-6XN and 254 SMO are more expensive due to their high levels of corrosion resistance and other specialized properties.

Overall, the cost of 1.4404 stainless steel will depend on a range of factors and should be evaluated in relation to the specific properties and requirements of the application. While 1.4404 stainless steel may be more expensive than some other grades, its excellent corrosion resistance and other properties may make it the best choice for certain applications.
