| High Light | ASTM A270 Stainless Steel Pipe ，Boiler Seamless Stainless Steel Pipe ，Stainless Steel Cold Drawn Tube | ||
The material used for cold drawn seamless pipes, specifically for boiler heat exchangers, conforms to the ASTM A270 standard. The ASTM A270 specification covers seamless and welded austenitic and ferritic/austenitic stainless steel sanitary tubing for general service.
The specification for the cold drawn seamless pipes, as per ASTM A270, includes the following key parameters:
The chemical composition of the stainless steel used in the ASTM A270 cold drawn seamless pipes is as follows:
| Element | Composition Range |
|---|---|
| Carbon (C) | 0.08% maximum |
| Manganese (Mn) | 2.00% maximum |
| Phosphorus (P) | 0.045% maximum |
| Sulfur (S) | 0.030% maximum |
| Silicon (Si) | 1.00% maximum |
| Chromium (Cr) | 16.00% - 18.00% |
| Nickel (Ni) | 10.00% - 14.00% |
The mechanical properties of the cold drawn seamless pipes, as per ASTM A270, are as follows:
| Property | Minimum Value |
|---|---|
| Tensile Strength | 515 MPa (74,800 psi) |
| Yield Strength | 205 MPa (29,700 psi) |
| Elongation | 35% minimum |
| Hardness (Brinell) | 170 maximum |
The stainless steel grade used in ASTM A270 cold drawn seamless pipes is typically Austenitic Stainless Steel 304 or 316L. These steel grades offer excellent corrosion resistance, high strength, and good formability, making them suitable for boiler heat exchangers.
The ASTM A270 cold drawn seamless pipes find extensive application in boiler heat exchangers, where they play a crucial role in facilitating the efficient transfer of heat between fluids. These pipes are designed to withstand high temperatures, pressure, and corrosive environments, making them ideal for various industrial and commercial boiler applications.
By adhering to the ASTM A270 standard, the cold drawn seamless pipes ensure compliance with industry regulations and provide reliable performance in demanding boiler heat exchanger systems.
