概述
ASTM A268 TP405 is a standard specification for seamless and welded ferritic and martensitic stainless steel tubing for general corrosion resistance and high temperature service. The "TP" in the name stands for "Seamless Pipe" and the "405" stands for a specific grade of stainless steel.
组成
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 meet certain tensile requirements， including minimum tensile strength， yield strength and elongation. These properties ensure that the pipe has the necessary mechanical strength.
Sizes and Specifications
SIZE RANGE: ASTM A268 TP405 stainless steel seamless steel pipe is available in a variety of sizes. This standard specifies the outside diameter and wall thickness requirements for steel pipe.
热处理
HEAT TREATMENT: Steel pipe under this specification may be subjected to heat treatment processes such as annealing or solution annealing to achieve the desired properties and microstructure.
