Grades Available for ASTM A312 Stainless Steel Pipes

The ASTM A312 standard includes several grades of stainless steel, each with unique chemical compositions and properties:

• ASTM A312 TP304: Standard 18/8 austenitic stainless steel offering excellent corrosion resistance.

• ASTM A312 TP304L: Low carbon version of 304, ideal for welding applications.

• ASTM A312 TP316: Molybdenum-added grade for improved resistance to pitting and crevice corrosion.

• ASTM A312 TP316L: Low carbon version of 316 for enhanced weldability.

• ASTM A312 TP321: Stabilized with titanium to prevent carbide precipitation.

• ASTM A312 TP347: Niobium-stabilized grade for high-temperature applications.

Types of ASTM A312 Stainless Steel Pipes

1. Seamless Pipes:
   Produced by extrusion without any weld joints, offering superior strength and corrosion resistance.

2. Welded Pipes:
   Manufactured by welding stainless steel strips or plates, suitable for low to medium-pressure applications.

3. ERW (Electric Resistance Welded) Pipes:
   Cost-effective option for general applications where high pressure is not a concern.
