Stainless Steel
316 / 316L
Stainless Steel 316 and Stainless Steel 316L pipes are the second most used among all stainless steel family, while SS 304 Pipe are widely commerce by stepping a little behind. The grades in this category, which contain around 16% chromium by weight and up to as much as 10–12% nickel (and sometimes molybdenum), are the most corrosion resistant of the stainless steels.
The only difference that exists between 316 and 316L is in the carbon level. Because it has maximum 0.03% of Carbon, 316L is the choice for welding material and preferable to use in various conditions especially that carbide precipitation should be consider Furthermore, Oil or gas industry may have a similar requirement due to high pressure& temperature. The low carbon also serves to increases its resistant to intergranular corrosion.
Chemical processing and marine applications both employ 316L materials in high frequency, as well is the pharmaceuticals and food production industries for sanitary levels of corrosion resistance. They are well known for their durability and have good formability too, which will give these types of fittings a long service life in many piping systems, tanks or other applications.
What are 316 / 316L Stainless Steel Pipe?
The 316 and 316L steel pipe is an alloyed-steel for the reason that if it does not contain markets overall reaches about molybdenum good corrosion resistance and quality mechanical properties. Here’s a breakdown of each:
316 Stainless Steel Pipe:
Composition: Iron, 16-18% chromium (Cr) 10-14% nickel (Ni) molybdenum (Mo) 2-3%, max. Carbon content of.
Properties: Good Corrosion resistance especially to chlorides and acidic environments. Yes, it is a little bit stronger than 316L stainless steel, but the reason for the high carbon content in 301stainless steel mainly to improve the wear resistance and hardening requirements. Given broad customer application helps you address your customer – over a variety of industry factories, including automotive applications respectively (sensitization when occurs after welding).
316L Stainless Steel Pipe:
Composition: Similar to 316 with lower carbon content (maximum of 0.03%).
Characteristics: With the reduced carbon material, it eliminates carbide precipitation during welding and therefore increases oxidation resistance. This is especially useful in unforgiving conditions.
Applications of 316 / 316L Stainless Steel Pipe
These 316 / 316L stainless steel pipes -600 are used in a wide variety of applications due to their excellent corrosion resistance and strength. Each one is used in many commonly renovated applications.
316 Stainless Steel Pipe uses:
Chemical Processing Transporting corrosive chemicals through pipes.
Boat Fittings, Hulls and other Marine Equipment: It is suitable for those containing in saltwater environments due to its resistance towards this situation.
Extract and transport pipelines for oil and natural gas.
Food and Beverage: To keep everything hygienic tanks, piping can equipment.
Used for Pharmaceuticals: in cleaning processes were corrosion resistance is important.
316L Stainless Steel Pipe Applications:
Welding Applications: especially for structures that need welding and which are related to sensitization occurring with the use of other stainless models.
Higher temperature environments – High oxidation resistance, such as when in the presence of high temperatures.
Marine Applications: Similar to 316 as it is used in the marine field, but has higher corrosion resistance with chloride enriched environments.
Biomedical Applications: Its biocompatibility and the ability to resist corrosion makes it a good option for use in medical devices, implants.
Pulp & Paper Industry: Used in equipment exposed to very harsh chemicals used during wood processing.
