ASTM A312 TP304 Welded Pipes for Agricultural Machinery
ASTM A312 TP304 is an austenitic alloy engineered with a high-quality nickel and chromium composition.
ASTM A312 TP304 is the standard for seamless and welded austenitic stainless steel pipe. It is a durable, corrosion-resistant material composed of approximately 18-20% chromium and 8-11% nickel. Key mechanical properties include a minimum tensile strength of 515 MPa (75,000 psi) and a minimum yield strength of 205 MPa (30,000 psi).
ASTM A312 TP304 grade pipe can be processed by hot or cold rolling. These pipes are available in thicknesses ranging from 0.8 mm to 12 mm and in various sizes and specifications to meet project needs.
