概述
ASTM A268 TP405 is a standard specification for seamless and welded ferritic and martensitic stainless steel tubing for general corrosion-resisting and high-temperature service. The "TP" in the designation stands for "tube， seamless，" and "405" is the specific grade of stainless steel.
Composition:
Chemical Composition: The composition of TP405 stainless steel typically includes chromium， manganese， silicon， sulfur， phosphorus， carbon， and iron. It is a ferritic stainless steel with good oxidation resistance.
机械性能
Tensile Requirements: The material must conform to certain tensile requirements， including minimum tensile strength， yield strength， and elongation. These properties ensure that the tube has the necessary mechanical strength.
Dimensions and Sizes:
Size Range: ASTM A268 TP405 Stainless Steel Seamless Tubes are available in a range of sizes. The standard specifies the outside diameter and wall thickness requirements for the tubes.
热处理：
Heat Treatment: Tubes under this specification may undergo heat treatment processes such as annealing or solution annealing to achieve the desired properties and microstructure.
