Product Description
ASTM A778 TP304L TP316L TP317L TP321 TP347 Welded Unannealed Austenitic Stainless Steel Tubular for Medical
Introduction
ASTM A778 is a standard specification for welded unannealed austenitic stainless steel tubular products. This specification is particularly relevant in the medical field, where the properties of the materials used are critical for ensuring safety and efficacy. The grades covered under this specification include TP304L, TP316L, TP317L, TP321, and TP347, each offering unique characteristics suitable for various applications.
Material Specification
The materials specified under ASTM A778 are designed to meet stringent requirements for corrosion resistance, mechanical properties, and weldability. The following grades are commonly used in medical applications:
- TP304L: Low carbon version of TP304, excellent corrosion resistance.
- TP316L: Contains molybdenum, enhancing resistance to pitting and crevice corrosion.
- TP317L: Higher molybdenum content for improved corrosion resistance.
- TP321: Titanium-stabilized grade, suitable for high-temperature applications.
- TP347: Niobium-stabilized grade, offering excellent high-temperature strength.
