SA240 Gr 304 Stainless Steel Pipe: Gangsteel Stainless Solution in China

Introduction to SA240 Gr 304 Stainless Steel Pipe

SA240 Gr 304 stainless steel pipe refers to pipes fabricated from SA240 Grade 304 stainless steel plate or sheet, specified under ASME SA240 for chromium-nickel stainless steel materials used in pressure vessels and general applications. It provides excellent corrosion resistance, weldability, and strength, making it suitable for industries like chemical processing, food production, and oil & gas. Gangsteel, a leading manufacturer and exporter in China, supplies SA240 Gr 304 stainless steel pipes in various sizes. As a specialist in ASME SA240 stainless steel plates, Gangsteel offers customized solutions for global clients. This article explains SA240 Gr 304 stainless steel pipe, its composition, properties, and uses.

What is SA240 Gr 304 Stainless Steel Pipe?

SA240 Gr 304 stainless steel pipe is made from austenitic stainless steel with 18–20% chromium and 8–10.5% nickel, providing balanced corrosion resistance and mechanical performance for piping systems. It is non-magnetic in annealed conditions and can be welded for pipe fabrication. Equivalent materials include UNS S30400, EN 1.4301, and JIS SUS304. Gangsteel’s SA240 Gr 304 is produced under ASTM A240 stainless plate specifications, ideal for pipe manufacturing and structural purposes.

Chemical Composition of SA240 Gr 304

The chemical composition of SA240 Gr 304 is defined by ASME SA240 to ensure corrosion resistance and durability for pipes. The table below lists the elements:

Gangsteel follows these compositions for SA240 Gr 304 pipes, compatible with JIS G 4304 stainless steel plate standards.

Mechanical Properties of SA240 Gr 304

SA240 Gr 304 stainless steel pipe exhibits mechanical properties suitable for piping applications. The table below summarizes these as per ASME SA240:

These attributes make SA240 Gr 304 pipes preferable over SA240 Gr 201, with Gangsteel offering SA240 Gr 304L for weld-specific needs.

Equivalent Materials for SA240 Gr 304

SA240 Gr 304 has equivalents across standards for flexible use in pipes. The table below lists common ones:

Gangsteel’s SA240 Gr 304 pipes integrate with these, aligning with ASTM A 959 stainless steel plates.

Applications of SA240 Gr 304 Stainless Steel Pipe

SA240 Gr 304 stainless steel pipe is applied in multiple sectors due to its resistance and strength. The table below highlights uses:

Gangsteel’s ASME SA 213/SA 213M stainless pipes complement SA240 Gr 304 pipes for systems.

Comparing SA240 Gr 304 with Other Grades

SA240 Gr 304 vs 316: SA240 Gr 304 offers general corrosion resistance and is cost-effective for mild environments, while SA240 Gr 316 includes molybdenum for better chloride resistance, suited for marine or harsh chemical applications.

SA240 Gr 304 vs 304L: SA240 Gr 304 provides higher strength, but SA240 Gr 304L, with lower carbon, offers superior weldability and resistance to intergranular corrosion.

SA240 Gr 304 vs 201: SA240 Gr 304 has better corrosion resistance due to higher nickel, making it ideal for outdoor use, whereas SA240 Gr 201 is more affordable but less durable in corrosive conditions.

SA240 Gr 304 vs 430: SA240 Gr 304 is austenitic and non-magnetic with excellent formability, while SA240 Gr 430 is ferritic, magnetic, and offers good resistance in less demanding settings but lower overall corrosion performance.

Gangsteel’s nickel alloy steel plates provide alternatives for extreme uses.
