Stainless Steel ASTM A268 TP405 Seamless Tube for Power Plants
We are YUHONG GROUP,one of the biggest manufactures of stainless steel & duplex steel & alloy steel tubes and pipes in China. With development more than 33 years, we have accumulated a great many clients all around the world and Yuhong products also won the great praise among the customers.
Overview
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.
Mechanical Properties:
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.
Heat Treatment:
Heat Treatment: Tubes under this specification may undergo heat
treatment processes such as annealing or solution annealing to
achieve the desired properties and microstructure.
