The ASTM A270 304 welded steel tube is constructed using high-quality stainless steel materials. This particular grade of stainless steel, known as Type 304, is a versatile and widely used material in various industries, including the automotive sector. Type 304 stainless steel is known for its excellent corrosion resistance, durability, and aesthetic appeal.
The ASTM A270 304 welded steel tube is manufactured in adherence to the standards set by the American Society for Testing and Materials (ASTM). It is designed as a mirror polished tube, featuring a round shape to provide structural integrity and improve fluid flow. The tube is welded using advanced techniques to ensure a seamless and precise construction. With a specific standard size range, this stainless steel pipe is tailored to meet the requirements of the automobile industry.
The key features of the ASTM A270 304 welded steel tube include:
The chemical composition of the ASTM A270 304 welded steel tube is as follows:
| Element | Composition (%) |
|---|---|
| Carbon (C) | 0.08 max |
| Silicon (Si) | 0.75 max |
| Manganese (Mn) | 2.00 max |
| Phosphorus (P) | 0.045 max |
| Sulfur (S) | 0.030 max |
| Chromium (Cr) | 18.00 - 20.00 |
| Nickel (Ni) | 8.00 - 10.50 |
The ASTM A270 304 welded steel tube exhibits the following mechanical properties:
| Property | Value |
|---|---|
| Tensile Strength | 515 MPa (minimum) |
| Yield Strength | 205 MPa (minimum) |
| Elongation | 40% (minimum) |
| Hardness (Brinell) | 201 HB (maximum) |
| Hardness (Rockwell B) | 92 HRB (maximum) |
The steel grade used in the ASTM A270 304 welded steel tube is Type 304 stainless steel. It is a highly versatile and widely used grade in the stainless steel family, known for its excellent corrosion resistance, durability, and formability.
The ASTM A270 304 welded steel tube is specifically designed for use in the automobile industry. It finds application in various components such as exhaust systems, piping, and structural supports. The mirror polished finish enhances the aesthetic appeal of the automobile's interior or exterior, making it a preferred choice for premium automotive manufacturers.
While Type 304 stainless steel is widely used and suitable for many automotive applications, certain alternative grades can also be considered based on specific requirements. Some possible alternative grades include Type 316 stainless steel, which offers even higher corrosion resistance, and Type 409 stainless steel, which is specifically designed for high-temperature exhaust systems. It is recommended to consult with a metal specialist to determine the best alternative grade for a particular application.
