Stainless steel continues to define the backbone of high-liquid industrial environments, and among the available grades, SS 310 seamless pipe has earned a reputation for reliability where thermal stability and oxidation resistance matter most. As industries shift toward faster, hotter, and more corrosive operating conditions, materials must withstand mechanical stress without degradation. SS 310, an austenitic grade engineered for such demands, offers a dependable solution – particularly when manufactured with precision and consistency, as practiced at Mangalam Worldwide.
Understanding SS 310: What Makes It a Heat-Resistant Steel
SS 310 belongs to the family of heat-resistant steel grades known for exceptional performance in elevated-temperature applications. Its chemical composition – featuring high chromium and nickel – creates a stable alloy structure that resists scaling and retains strength at temperatures that would distort or weaken conventional stainless steels.
Key Metallurgical Features
- High chromium (24%–26%)
Enhances oxidation resistance, even under continuous exposure to 1000°C+. - Nickel content (19%–22%)
Stabilizes the austenitic structure and supports mechanical integrity during thermal cycling. - Low carbon
Minimizes carbide precipitation, maintaining corrosion resistance during heat exposure.
These characteristics make SS 310 seamless pipes suitable for environments where dimensional stability and resistance to warping are essential.
Why Seamless Construction Matters
A seamless pipe differs significantly from welded variants because it does not contain longitudinal seams or joints. For SS 310 seamless pipe, this is particularly important in extreme-temperature and high-pressure zones.
Advantages of Seamless SS 310 Pipes
- Uniform strength across the pipe length
- Lower risk of creep failure in elevated-temperature service
- Stable thermal expansion, essential in cyclic heating systems
- Consistent dimensional accuracy ideal for precision assemblies
Mangalam Worldwide manufactures seamless stainless steel pipes with stringent control on piercing, hot-rolling, sizing, and heat-treating parameters – ensuring consistent mechanical properties and surface quality.
Specifications of SS 310 Seamless Pipe
Although SS 310 pipes are available in a variety of configurations, the following specifications generally define industrial-grade quality:
1. Standards & Compliance
Typical standards include:
- ASTM A312 / ASME SA312
- EN and DIN equivalents depending on application
2. Dimensions & Size Range
- Outer diameter: generally from 6 mm to 168 mm
- Wall thickness: from SCH 5 to SCH 160
- Forms: round, hydraulic, boiler-grade, precision tubes
Mangalam Worldwide’s operational flexibility ensures that customers receive the exact dimensions required for specialized conditions.
3. Mechanical Properties
- Tensile strength: approx. 515 MPa
- Yield strength: approx. 205 MPa
- Elongation: typically 40%+
- Hardness: optimal for elevated-temperature resistance
4. Temperature Resistance
- Suitable for continuous service up to 1050°C
- Performs well during intermittent exposure up to 1150°C
These specifications reflect why SS 310 remains a preferred material for environments involving open flames, exhaust gas, molten metals, and thermal process lines.
