Grades and what they suit
Altra Enterprise is among the biggest sellers of stainless steel seamless pipes and tubes used industrially in a huge variety of grades. Pick the optimum grade for corrosion resistance, operating temperature, fabrication and process media.
| Grade | Key Characteristics and Typical Applications |
|---|---|
| 304 / 304L | Suitable for selected elevated-temperature and welded applications where sensitisation resistance is required. Titanium-stabilised austenitic grades. Suitability is dependent on operating temperature and service conditions. |
| 316 / 316L | An alloy that contains molybdenum for greater corrosion resistance than 304 in a number of chloride environments as well as corrosion resistance against a variety of chemicals. Often used in chemical processing, pharmaceutical, and marine applications. 316L grades have a lower carbon content for welded applications. |
| 316Ti / 321 | Titanium-stabilised austenitic grades used in selected elevated-temperature and welded applications where resistance to sensitisation is important. Suitability depends on the operating temperature and service conditions. |
| 309 / 310 / 310S | Higher-chromium and higher-nickel heat- and corrosion-resistant stainless steel grades used for all appropriate elevated temperature service, such as furnace linings, heat treatment equipment and industrial thermal systems. |
| Duplex 2205 | A duplex stainless steel with a two-phase microstructure consisting of ferritic and austenitic steels that offers high strength over typical austenitic grades and excellent chloride stress-corrosion cracking resistance. |
| Super Duplex 2507 | Duplex 2507 is a high-alloy grade of duplex designed for use in the most demanding environments with high concentrations of chlorides. It’s commonly utilized in a small number of offshore, marine, and chemical processing applications. |
Note: Performance in actual use will depend upon temperature, chloride ion levels, and chemical formulation, manufacturing, heat treatment, and application.

We ensure all SS seamless pipes adhere to ASTM A269, ASTM A511, ASTM A213, and ASTM A554 standards. Also, standard EN and JIS pipes are supplied on request. In addition to this, Mill Test Certificates and 3rd party inspection reports are also supplied as proof.
Q.5. What are the surface finishes of the SS seamless pipes?
SS seamless pipes are available in a wide array of SS seamless pipe finishes, including the mill, pickled, bright, annealed, electropolished, and mechanically polished finishes. We not only offer these finishes but also other specialized value-added services like SS cutting, SS threading, SS beveling, SS passivation, and SS special packaging, which speed up your project delivery and also simplify on-site usage by avoiding further operations at the site.
Q.6. What are the key application areas of SS seamless pipes?
SS seamless pipes are most commonly utilized in the oil and gas sector, and in chemical and petrochemical plants. We serve the pharmaceutical and food processing industries with our pipes and also supply to the power generation sector and marine applications. They can also be found in hydraulic and instrumentation systems, as they are designed for high-pressure usage.
Q.7. How do seamless and welded SS pipes differ?
Seamless pipes don’t have a weld seam and are typically made using the rotary piercing or extrusion methods. As they are one piece, seamless pipes have greater strength and can withstand more pressure than their welded counterparts, especially when used in critical and high-pressure oil, gas, chemical, and power industry applications where robustness is a key consideration.
