ASTM A312 TP304 Stainless Steel Seamless Thick-Walled Tube
ASTM A312 TP304 Stainless Steel Seamless Thick-Walled Tube
ASTM A312TP304 seamless thick-walled tube is a corrosion-resistant, high-temperature-resistant austenitic stainless steel tube designed for high-pressure applications. Its key properties include 18-20% chromium and 8-11% nickel content, a minimum tensile strength of 515 MPa (75,000 psi), and a minimum yield strength of 205 MPa (30,000 psi). Due to its strength and corrosion resistance, this tube is widely used in commercial, industrial, and chemical industries.
What is ASTM A312 TP304?
A312 TP304 is an austenitic stainless steel alloy designed with a high-quality nickel-chromium alloy ratio. ASTM A312 TP304 alloy exhibits excellent corrosion resistance and oxidation resistance under various stress environments. This versatile alloy also possesses excellent mechanical properties.
ASTM A312 TP304 Stainless Steel Seamless Pipe (Thick Wall), suitable for general corrosive environments
Gnee Steel has been dedicated to the production of seamless welded steel pipes made of austenitic stainless steel and nickel alloy steels (Hastelloy, Monel, Incol, etc.), with annual sales exceeding 200,000 tons. Our customers are located in over 45 countries and regions, including Italy, the UK, Germany, the USA, Canada, Chile, Colombia, Saudi Arabia, South Korea, Poland, Singapore, Australia, and France.
A312 TP304 steel pipes are typically formed from round steel billets through a push-draw process, offering superior corrosion resistance compared to ordinary 304 stainless steel pipes. Our 304 stainless steel seamless pipes have a low carbon content, resulting in excellent welding and forming properties. 304 stainless steel welded pipes can be manufactured in various shapes, such as 304 stainless steel round pipes or 304 stainless steel square pipes. 304 stainless steel ERW pipes are suitable for long-term applications in chemical and industrial fields. Our products are of superior quality and offered at highly competitive prices.

Design and Structure
Seamless Structure: "Seamless" refers to the absence of welds during the product manufacturing process, resulting in higher strength and better suitability for high-pressure applications.
Thick Wall: "Thick wall" refers to a larger wall thickness, enhancing strength and durability.
Corrosion Resistance: The chromium oxide layer formed on the surface provides self-healing corrosion protection in the presence of oxygen.

Gnee Steel specializes in the production of a wide range of stainless steel products. Gnee Steel's product packaging includes: Steel Strapping: Pipes with an outer diameter of 3 inches or less are typically strapped together with polypropylene film to prevent rust during ocean shipping, and then secured with steel strapping. Wooden Cases/Crates: Pipes are typically packaged in wooden cases or crates to protect the pipes during transportation, especially those that are longer or have larger diameters. Seaworthy Export Packaging: Suppliers typically use standard seaworthy export packaging methods, which may include a variety of materials and techniques to protect the pipes during transportation. Tarpaulin Packaging: This prevents rain, seawater, and other external factors from penetrating the export crates during transportation. Gnee Steel specializes in the production and sale of alloy materials. Gnee Steel's products are widely used in the aerospace, chemical, power, automotive, and nuclear energy sectors, and we can provide customized alloy material solutions based on customer needs.
