Stainless Steel Flat Bar ASTM A276 SS304 for Power Industries
Overview
A276 SS304 is a standard specification for stainless steel bars and shapes, issued by the ASTM International organization. SS304 refers to the grade of stainless steel, which contains a minimum of 18% chromium and 8% nickel.
A276 SS304 flat bar is a type of stainless steel bar that has a flat rectangular shape. It is widely used in various industries due to its corrosion resistance, high strength, and excellent formability. The flat shape of the bar makes it suitable for applications such as structural support, architectural trim, industrial equipment, and more.
The dimensions and properties of A276 SS304 flat bar can vary depending on the specific requirements of each application. Typically, the width and thickness of the flat bar range from a few millimeters to several inches, while the length can be customized to meet the project's needs.
Some of the key characteristics of A276 SS304 flat bar include its ability to withstand high temperatures, resistance to oxidation and scaling, and good weldability. It is also easy to clean and maintain, making it a popular choice for applications in food processing, chemical processing, and other industries where hygiene and cleanliness are crucial.
In summary, A276 SS304 flat bar is a versatile and durable stainless steel product that offers excellent corrosion resistance, high strength, and formability. It is widely used in various industries for applications that require a flat, rectangular shape with superior performance in harsh environments.
Description
ASTM A276 304 Universal stainless steel plates contain up to 8% nickel and 18% chromium, giving them excellent oxidation resistance at temperatures up to 1,600 °F. It is easy to form or weld, can withstand heat and corrosion, and responds well to hardening by cold working.
What is difference between A276 and A479?
A479 specifically refers to use in boiler and pressure vessel applications. A276 specifically defers bars for reforging and free machining grades to other ASTM standards (A314 and A582/A582M) while A479 is silent on those items and they are presumed to not be covered.
