ASTM403 WP321 180 Degree Stainless Steel Elbow

ASTM A403 WP321 180 degree stainless steel elbow is a high-quality, corrosion-resistant fitting for applications where durability, heat resistance, and resistance to chemical attack are critical. It is commonly used in industries such as food and beverage, chemical processing, power generation, and aerospace.
Generally used for piping, industrial, and construction. ASTM A403 is the American Society of Mechanical Engineers (ASME) specification for pressure vessels and piping components, primarily for carbon, alloy, and stainless steel piping systems. It covers both seamless and welded fittings. Made from 321, an austenitic stainless steel known for its excellent corrosion resistance, heat resistance, and weldability. When an elbow has a 180-degree bend, it means that it forms a complete U-shape. This allows the pipe to change direction without adding additional straight lengths, which helps minimize material usage and maintain fluid flow efficiency.

Stainless Steel Butt Weld Fittings
Stainless Steel Butt Weld Fittings are a type of pipe fitting used in plumbing, industrial, and architectural applications where high durability, corrosion resistance, and chemical inertness are essential. These fittings are made from austenitic stainless steel alloys like 304, 316, or 316L, which are known for their excellent strength, toughness, and resistance to corrosion from various chemicals, moisture, and environmental factors.

STAINLESS STEEL 321

Stainless Steel 321, also known as UNS S32100, is a corrosion-resistant austenitic stainless steel specifically designed for elevated temperature applications. It is an alloy of approximately 18% chromium, 9% nickel, and a small amount of molybdenum (usually around 4-5%). The addition of molybdenum makes it particularly resistant to thermal creep, which is the tendency for materials to weaken and deform at high temperatures.
