A403 WP321 STAINLESS STEEL SR ELBOW BUTT WELD 180 DEGREE B16.11

Overview

WP321 BW elbow refers to a butt weld elbow made from stainless steel grade WP321. This type of elbow is used in piping systems to change the direction of flow. The "BW" stands for butt weld, indicating that the elbow is designed to be welded to the pipe for a secure and leak-proof connection. WP321 is a grade of stainless steel known for its high corrosion resistance and strength, making it suitable for use in various industries and applications.

Characteristics of SS321

Corrosion Resistance: SS321 provides excellent resistance to corrosion, especially in high-temperature environments.
High Temperature Resistance: It can withstand elevated temperatures up to 900°C (1650°F) without losing its mechanical properties.
Weldability: SS321 is easily weldable with most standard welding methods, making it suitable for a wide range of fabrication processes.
Creep Resistance: It has good creep strength, making it ideal for applications where the material is subjected to prolonged high temperatures.
Oxidation Resistance: SS321 offers good resistance to oxidation, ensuring long-term durability in various demanding conditions.
Stability: It is stabilized with titanium, which prevents the formation of harmful carbides at high temperatures, improving its resistance to intergranular corrosion.

These characteristics make Stainless Steel 321 a popular choice for applications in industries such as aerospace, automotive, chemical processing, and more.
