Detailed Image
The ASTM A270 standard is developed for seamless and welded austenitic stainless steel tubing used in the food industry, pharmaceutical industry, and similar hygienic conditions. However, due to its excellent corrosion resistance and pressure-bearing capacity, this standard tubing is also widely used in other industrial sectors that require high pressure resistance, including the automotive industry. As one of the most commonly used stainless steels, 304 stainless steel is popular because of its good comprehensive properties. Combining these two advantages, ASTM A270 304 seamless stainless steel tubing is a natural choice for automotive high-voltage systems.
Seamless Fabrication: Advanced seamless steel tube manufacturing techniques, such as hot-rolled perforation, cold-rolling, or hot-extrusion, ensure that the tubes have uniform wall thickness and excellent mechanical properties. The seamless construction allows the tubing to maintain structural integrity and stability when subjected to high pressures.
High-precision machining: precision machining through multiple processes, such as sizing, straightening, cutting and polishing, etc., to meet the strict requirements of the automotive industry for tube dimensional accuracy and surface quality. The high-precision processing ensures the accuracy and reliability of the pipe during installation and use.
Quality inspection: Strict quality inspection of finished pipes, including chemical composition analysis, mechanical property testing, hydrostatic testing and surface quality inspection, etc. Ensure that each tube meets the ASTM A270 standard and the specific requirements of the automotive industry.
Chemical and Mechanical Composition:
| Standard | Steel Grade | C | Si | Mn | P | S | Cr | Ni | Mo | Ti | YS(Mpa) | TS(Mpa) | EL(%) | HRB |
| ASTM A270 | 304 | <=0.08 | <=1.00 | <=2.00 | <=0.045 | <=0.030 | 18.0-20.0 | 8.0-11.0 | — | — | >=205 | >=515 | >=35 | <=90 |
Seamless construction and high-quality materials allow this tubing to withstand extremely high operating pressures and meet the demands of automotive high-pressure systems.
304 stainless steel has excellent corrosion resistance, can resist the erosion of a variety of corrosive media, and ensures the long-term stable operation of the pipeline system.
The pipe is easy to cut, bend and weld and other processing operations, which is convenient for on-site construction and installation. At the same time, the good welding performance ensures the firmness and tightness of the pipeline connection.
ASTM A270 compliant tubing has a high surface finish, is easy to clean and maintain, and meets the stringent hygienic requirements of the automotive industry.
ASTM A270 304 High Pressure Resistant Seamless Stainless Steel Pipe is mainly used in the automotive industry in the following aspects:
Fuel system: It is used in high-pressure fuel injection systems and fuel lines to ensure efficient fuel transmission and accurate injection.
Cooling system: It is used in the cooling system of high-performance engines, and can withstand the flow of coolant at high temperature and high pressure to ensure the cooling effect of the engine.
Braking system: Although stainless steel is not usually used for braking systems, the high pressure and corrosion resistance of this tubing also has certain advantages in some special applications, such as some components of hydraulic braking systems.
Air conditioning and heating systems: In the air conditioning and heating systems of automobiles, this type of pipe can be used to transfer media such as refrigerant or hot water to ensure a comfortable environment in the car.
ASTM A270 304 High Pressure Resistant Seamless Stainless Steel Pipe plays an important role in the automotive industry with its excellent performance and reliable quality. It not only meets the stringent requirements of high-pressure systems, but also provides excellent corrosion resistance and processability. With the continuous development of the automobile industry, the application prospect of this pipe will be broader.
