316L Stainless Steel Rectangle Tube has internal and external radius corners, with a protruding interior weld seam. Stainless Rectangle Tube is ideal for all structural applications where greater strength and superior corrosion resistance is required. Having a durable mill finish Stainless Rectangle Tube is widely used for all types of fabrication projects that are exposed to the elements - chemical, acidic, fresh water, and salt water environments. Some sizes are available with a 180 grit polish.
316L stainless has high strength and excellent corrosion resistance, including in marine or extremely corrosive environments. It is stronger, though less malleable and machinable than 304.316L Stainless Steel Pipe is normally used in natural gas / petroleum / oil, aerospace, food and beverage, industrial, cryogenic, architectural, and marine applications.
Type 316L Stainless Steel is an extra-low carbon version of Type 316 that minimizes harmful carbide precipitation in the heat affected zone during welding.
316L stainless steel is more resistant to corrosion than 316 stainless steel. There may be no difference in everyday applications. However, because of its weldability, 316L is regarded as the superior corrosion resistance option. 316Ti is essentially 316 with some titanium (Ti) added to reduce the risk of corrosion resistance loss in the heat-affected zone. To avoid this, the carbon(C) level can be reduced, resulting in the grade 316L.
