ASTM A789/ASME SA789 Stainless Steel Pipe Ferritic Stainless Steel Tubing For General Service
Introduction
The ASTM A789/ASME SA789 specification covers seamless and welded ferritic/austenitic stainless steel tubing for general service. This type of stainless steel pipe is widely used in various industries due to its excellent corrosion resistance and high strength.
Material
The ASTM A789/ASME SA789 stainless steel pipe is made from a combination of ferritic and austenitic stainless steels. The most commonly used grades include:
- Grade TP 304: This grade contains 18% chromium and 8% nickel.
- Grade TP 304L: Similar to Grade TP 304, but with a lower carbon content to improve weldability.
- Grade TP 316: Contains 16% chromium, 10% nickel, and 2% molybdenum, offering increased corrosion resistance.
- Grade TP 316L: Similar to Grade TP 316, but with a lower carbon content for improved weldability.
Specification
The ASTM A789/ASME SA789 stainless steel pipe specifications include:
- Size Range: The pipes are available in various sizes, ranging from 1/8" to 30" (10.3mm to 762mm) in outer diameter.
- Wall Thickness: The wall thickness can vary from SCH 5S to SCH XXS.
- Length: Standard pipe lengths are 20 feet (6 meters) or customized according to specific requirements.
