Products Specification

Description of 316L stainless steel polished welded pipe
316L stainless Steel polished welded pipe is a low carbon version of 316 stainless steel that has been welded and polished for a smooth surface and high corrosion resistance. It is widely used in industries that require high hygiene standards and corrosion resistance.

Chemical composition
The main chemical composition of 316L stainless steel is as follows:

• Carbon (C): ≤0.03%
• Silicon (Si): ≤1.00%
• Manganese (Mn): ≤2.00%
• Phosphorus (P): ≤0.045%
• Sulfur (S): ≤0.030%
• Nickel (Ni): 10.0-14.0%
• Chromium (Cr): 16.0-18.0%
• Molybdenum (Mo): 2.0-3.0%

peculiarity

• Corrosion resistance: Excellent resistance to chlorides and other corrosive media.
• Low carbon content: Reduce carbide precipitation during welding and reduce the risk of intergranular corrosion.
• Polished surface: Smooth surface reduces dirt accumulation and is easy to clean.
• High strength: Good mechanical properties at high and low temperatures.
• Biocompatibility: Suitable for the food and pharmaceutical industries.
