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
  • Piping
  • Fasteners
  • 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 –


304L Stainless Steel Welded Pipe


  • 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
  • Non-magnetic

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.

Choose the right Stainless Steel Standards and Grade

The standards for stainless steel pipes are influential in specifying, evaluating and classifying the properties of various types of steels in various applications. All stainless steel pipes for example, ss 304L sheetare rust –resistant, modern and sleek, however some grades work better as compared to others. SS 316 and SS 304 are the most regular grades of stainless steel pipes. The 316 stainless steel sheet suppliers also confirmed that these pipes offers better corrosion resistance.

Selecting Right stainless steel Pipes

Selecting the right stainless steel pipes is an important decision to make. With so many ss 316l sheet suppliersit becomes difficult to decide which one to choose. Seamless pipes of stainless steel have a 20% high working pressure, while welded pipes of stainless steel of the same size and materials provides corrosion resistance, that allow differences malleability and potential defects.

ST52 Pipe is a Low-Carbon, non-alloyed, and manganese steel that is basically in sheet format and round that have wider range of applications, especially at welded constructions. Most st52 pipe suppliersare completely involved in the amazing quality of the product of detailed ranges of pipes. When it comes to Inconel pipe, it is basically a nickel-chromium blend that also has aluminum. Seamless Inconel Pipe is oxidation-corrosion-resistant items that are well suited for service in harsh weather conditions subjected to heat and pressure. These types of pipes are usually a nickel that contain alloy which is apt for harsh temperatures and corrosion resistant. It looks like the alloys namely Hastelloy, Monel and Incoloy.

inconel 600 pipe suppliers offer a variety of pipes and they are relied on the various types of inconel. You can get Inconel Lined Pipe in all types of sizes and grades. These types of pipes can be customized to accomplish the particular requirements of clients. Inconel 625 Pipecan be used in different industries such as machinery, oil extraction, paper, food containers, construction, medicine, food, chemicals etc. Inconel straight pipes can deal with extremely high pressures. Now, let’s have a look at Hastelloy PipeThey have strong resistance against stress corrosion, cracking, and localized corrosion. Material specification of these pipes is an economical and a long-term solution to avoid damage.

The liquids employed in chemical processing are very mordant, plus the materials of creation for the processing apparatus need very special concern. Without the right arrangement, conditions will quickly turn down, causing unit replacement and repair and classy manufacturing downtime. Monel alloys are created by combining copper and nickel, with extra elements. Monel Pipe provide both cost effectiveness and exceptional performance. Monel alloy tubes and pipes are accessible on two important grades: MONEL alloy K-500, and MONEL alloy 400. These seamless pipes are engineered and designed with the use of best quality stainless steel together with international norms and quality standards. The monel welded pipes are also presented in various shapes and sizes to the clients. Mixing components in monel pipes also contain an effect on the eutectoid heat of the steel.
