TP321 Seamless Stainless Steel Pipe

Introduction

TP321 stainless steel pipe is a type of stainless steel pipe that is widely used in various industries due to its excellent properties and durability. TP321 is derived from the 321 grade of stainless steel, which contain Titanium to enhance its corrosion resistance and high-temperature strength.

 

Features of TP321 seamless stainless steel pipe

1. Good corrosion resistance: TP321 stainless steel seamless steel pipe has a long service life in various corrosive media such as acid, alkali, salt, etc., which can effectively prevent medium leakage and pollution.

2. High-temperature resistance: The addition of titanium elements effectively improves the intergranular corrosion resistance of stainless steel pipe in high-temperature environments, making it still maintain stable mechanical properties in high-temperature environments ( the maximum temperature can reach 816℃)

3. High strength and excellent mechanical properties: TP321 seamless stainless steel pipe has high strength and excellent mechanical properties. The tensile strength is more than 515 Mpa, and the yield strength is more than 205 Mpa. It is not easy to deformation or damage in high-pressure environments.
