As a globally recognized benchmark for corrosion resistance and structural integrity, ASTM 304 Stainless Steel Pipe remains the backbone of modern industrial infrastructure. From high-pressure chemical processing to the delicate requirements of food-grade transportation, Shaanxi Kerlimar Engineers Co., Ltd. provides unrivaled expertise and information gain through decades of specialized manufacturing and international trade.
Established in 2003, Shaanxi Kerlimar Engineers Co., Ltd. has evolved from a local manufacturer to a global powerhouse in the piping industry. Our two-decade journey is marked by rigorous adherence to international standards and a commitment to material purity.
Our manufacturing protocols strictly follow ASTM, ASME, EN, and JIS frameworks. This ensures that every pipe leaving our facility meets the precise tolerances required for aerospace, nuclear, and high-tech energy applications.
With more than 40 national and international patents (PCT), we don't just supply steel; we engineer solutions. Our integration of vertical axis wind power technology into industrial manufacturing showcases our commitment to "New Quality Productive Forces."
In the current global economic landscape, the demand for ASTM 304 Stainless Steel is experiencing a paradigm shift. Traditionally used in heavy construction, the focus has moved toward Sustainability and Circularity. According to recent industrial whitepapers, 304 grade steel is now the preferred material for green energy infrastructure due to its 100% recyclability and long lifecycle.
The "Search Intent" for global procurement teams has shifted from "lowest price" to "Supply Chain Reliability and Carbon Footprint." This is where Shaanxi Kerlimar stands out—integrating clean energy solutions into our production logic, as evidenced by our participation in the Dubai COP28 Conference.
China's stainless steel ecosystem allows for real-time sourcing of high-purity chromium and nickel. This reduces lead times by 30% compared to Western competitors, ensuring timely delivery of bulk orders.
Leveraging Industry 4.0, our Shaanxi facilities utilize AI-driven ultrasonic testing and automated welding to ensure zero-defect production in seamless and ERW pipes.
By optimizing energy consumption—using our patented vertical wind turbine technology—we lower manufacturing costs without compromising the metallurgical integrity of the ASTM 304 grade.
ASTM 304 (UNS S30400) is a T-300 series stainless steel austenitic. It has a minimum of 18% chromium and 8% nickel, combined with a maximum of 0.08% carbon. This specification is crucial for preventing Intergranular Corrosion during welding.
| Chemical Composition | Element Percentage (%) | Mechanical Properties | Value |
|---|---|---|---|
| Chromium (Cr) | 18.0 - 20.0 | Tensile Strength | ≥ 515 MPa |
| Nickel (Ni) | 8.0 - 10.5 | Yield Strength | ≥ 205 MPa |
| Carbon (C) | ≤ 0.08 | Elongation | ≥ 40% |
| Manganese (Mn) | ≤ 2.0 | Hardness (Brinell) | ≤ 201 HBW |
