What are applications of 1.4429 stainless steel?
1.4429 is a grade of austenitic stainless steel, also known as AISI 316LN or EN 1.4429. It is a low-carbon, nitrogen-enhanced version of AISI 316 stainless steel, which provides increased tensile strength and improved resistance to pitting and crevice corrosion. The chemical composition of 1.4429 stainless steel is as follows:
– Carbon (C): 0.030% max
– Silicon (Si): 1.00% max
– Manganese (Mn): 2.00% max
– Phosphorus (P): 0.045% max
– Sulfur (S): 0.015% max
– Chromium (Cr): 17.00 – 19.00%
– Nickel (Ni): 12.50 – 15.00%
– Nitrogen (N): 0.12 – 0.22%
The addition of nitrogen to 1.4429 stainless steel improves its strength and corrosion resistance, especially in environments containing chlorides. It is commonly used in applications such as chemical processing equipment, heat exchangers, and marine equipment.
1.4429 stainless steel is also known for its good welding and forming properties, making it suitable for use in fabrication and welding processes. However, care should be taken when welding to avoid the formation of sensitization and intergranular corrosion in the heat-affected zone.
It is worth noting that due to the low carbon content, 1.4429 stainless steel has lower temperature resistance compared to AISI 316 stainless steel.
1.4429 stainless steel, also known as AISI 316LN or EN 1.4429, is a low-carbon, nitrogen-enhanced version of AISI 316 stainless steel that provides increased strength and improved resistance to pitting and crevice corrosion. Here are some other applications of 1.4429 stainless steel:
