Hot Sale ASTM 321 Stainless Steel Round Bar

Product Overview

Our hot - sale ASTM 321 stainless steel round bar is a high - quality product designed to meet a wide range of industrial and commercial needs. Manufactured by Wuxi Weiman Gaodeng Special Steel Co., Ltd., a reputable manufacturer established in 2017, this round bar is known for its exceptional performance and reliability. With an annual export volume ranging from US$5 Million to US$10 Million, we have a strong presence in major markets across the globe, including North America, South America, Europe, Asia, Africa, and Oceania.

Material Specification

Chemical Composition

The ASTM 321 stainless steel round bar is composed of a carefully balanced blend of elements. It contains chromium (Cr) in the range of 17.0 - 19.0%, which provides excellent corrosion resistance. Nickel (Ni) is present at 9.0 - 12.0%, enhancing the material's toughness and ductility. Titanium (Ti) is added in a minimum of 5 times the carbon content, up to a maximum of 0.70%. This addition of titanium stabilizes the steel against intergranular corrosion, especially when exposed to high - temperature environments.

Mechanical Properties

In terms of mechanical properties, the round bar has a minimum tensile strength of 515 MPa and a minimum yield strength of 205 MPa. The elongation at break is typically around 40%, indicating its good formability. These properties make it suitable for various applications that require both strength and the ability to be shaped.

Shape and Dimensions

Round Shape

The bar comes in a round shape, which is one of the most versatile and commonly used geometries in engineering and manufacturing. The round shape provides uniform stress distribution, making it ideal for applications such as shafts, axles, and fasteners.

Available Sizes

We offer a wide range of diameters for the ASTM 321 stainless steel round bar, starting from as small as 6 mm up to 300 mm. The length of the bars can be customized according to the customer's requirements, with standard lengths available from 3 meters to 6 meters. This flexibility in sizing allows our customers to choose the most appropriate dimensions for their specific projects.

Applications

Aerospace Industry

In the aerospace industry, the ASTM 321 stainless steel round bar is used for manufacturing components such as engine parts, landing gear components, and structural elements. Its high - temperature resistance and excellent mechanical properties make it suitable for withstanding the extreme conditions encountered in flight.

Chemical Processing

For chemical processing plants, the round bar is used in the construction of pipes, valves, and fittings. Its corrosion resistance to a wide range of chemicals, including acids and alkalis, ensures long - term durability in harsh chemical environments.

Food and Beverage Industry

In the food and beverage industry, the bar is used for equipment such as conveyor systems, mixing tanks, and processing machinery. The stainless steel's hygienic properties, along with its resistance to corrosion from food acids and cleaning agents, make it a safe and reliable choice for food - contact applications.
