What is ASTM B407 Pipe?

The ASTM B407 alloy consist of nickel, iron, and chromium. This specification is generally for seamless pipes and tubes, and they cover Incoloy 800 and Incoloy H/HT. It generally covers them in hot finishes or cold worked seamless ASME SB 407 Tubing or piping. The Incoloy 800 are usually found in service temperatures that go up to 593 °C. Incoloy 800H/HT can be used above 593 °C where resistance to creep and rupture is an essential requirement.

ASTM B407 Pipes are also known for their high resistance to chloride-ion related stress corrosion cracking. Due to these properties, the SB 407 Material is used in applications taking place in high temperature environments like process piping, nuclear steam generator, heat exchangers, etc.

What is ASTM B407 Seamless Tube?

The ASTM B407 Seamless Tube does not come with any welding seam as they are made from solid steel in the form of sheet or bar. They are given a solid round shape known as a billet. They are then heated and cast over a form like a piercing rod to create a hollow tube or shell.

The ASME SB 407 Seamless Tubing solutions are used in the chemical processing industry like in chemical lines and control lines as they are less prone to leakage due to the absence of any weak seams. The DIN 2.4854 Seamless Tube is manufactured through hot rolling, cold rolling, or cold drawn processes.

What is ASTM B407 UNS N08120?

ASTM B407 UNS N08120 Tube has a high nickel content in its alloy and offer good resistance to heat. They offer great high temperature strength and resistance to oxidation. The tubes come with a coarse grain structure and they can be controlled by high temperature heat treatment. ASTM B407 Tubes are well known for particularly offering high creep strength. Their mechanical properties like yield and tensile strengths varies with the heat treatment applied.
