How to choose the right grade between various Stainless steel options
Austenitic stainless-steel grades are considered as the best option for materials that can survive sarcastic environments. Austenitic stainless steels are rich in nickel and chromium, which make it the best option to resist corrosion. Also, it has a wonderful mechanical specifications across the different accessible grades in the market.
1. Stainless steel Grade 304
304 Stainless Steel Pipe is a fundamental austenitic stainless steel. It consist of higher amount of chromium and nickel, with the level of chromium varying from 18% to 20% by weight, while the weight of nickel vary between 8% to 10.5%. other alloying elements of grade 304 consist of manganese and silicon with iron that contain remaining chemical opus. Nickel and Chromium give 304L Stainless Steel Pipeits high corrosion resistance. Some standard application areas for stainless steel 304 grade include –
- Commercial food processing appliances
- Building structures in the milieu that would corrode carbon steel
- Heat exchangers
- Household appliances
2. Stainless steel Grade 316
It has the identical material opus similar to 304 stainless steel. But, besides having higher level of nickel and chromium, Stainless Steel 316 Pipe also contain manganese, carbon, molybdenum, and silicon with a higher level of iron. The addition of molybdenum enhances the alloys decay resistance, especially with better resistance to crevice and pitting corrosion in chloride environments. Stainless Steel 316L Pipe has austenitic structure that gives excellent robustness, even down to cryogenic temperatures. Such grades have outstanding weld-ability, without or with the accumulation of filler metal. Some standard application areas for stainless steel 304 grade include –
- Medical devices
- Chemical storage tools and for chemical processing
- Refinery equipment
- Marine surroundings
3. Stainless steel 904L
Stainless Steel 904L Pipe is a high alloy variant of austenitic stainless steel which is famous for its corrosion resistance properties. This lesser carbon edition of stainless steel also provides other perks to users such as –
- Excellent weldability and formability
- High resistance to stress corrosion cracking and crevice
- Better resistance to acetic acids, phosphoric, and sulphuric acids
- Stronger corrosion properties as compared to type 317L, 316L, and SS 304 flanges
All of the grades of 904L stainless steel that Stainless Steel Pipe manufacturers in India offers meets standard manufacturing specification such as EN, ASTM and more.
4. Carbon steel piping
It is a durable and strong material that is formed of carbon steel, a steel mixed with carbon and iron. Due to its ability to withstand stress and strength, Carbon steel pipe is employed in a range of heavy-duty industries such as chemical fertilizer equipment, distillers, ships, and infrastructure. Duplex pipe manufacturer india provides a variety of carbon steel pipe to fulfill all your application requirements, such as custom sizes and hard-to-find sizes.
You will have to consider a lot of factors while deciding what grade or type of stainless steel tubing to pick. The major feature to look for while choosing stainless steel pipes is to ensure that they are corrosion resistant for a particular environment or application. You should also keep an account for fabrication and strength characteristics.
