Alloy Steel Pipe Supplier

We take pride in offering a diverse selection of ASTM 335 Alloy Steel Pipes & Tubes, known for their exceptional quality and enduring durability. Our range encompasses various sizes, grades, specifications, and shapes, providing versatility to meet a multitude of needs. Whether it’s seamless or welded, our products adhere to the stringent ASME B16.11 standards and international benchmarks.

Our Alloy Steel Seamless Tubes serve as vital components in a wide spectrum of industries, including oil refineries, chemical plants, fertilizer facilities, petrochemical plants, and sugar mills. Their adaptability and reliability make them invaluable in these demanding environments.

We offer ASTM 335 Alloy Steel Boiler Tubes at competitive prices, ensuring accessibility without compromising on quality. These tubes are a testament to precision engineering and serve as essential elements in various applications.

Ferritic Alloy Steel Pipes are known for their high chromium content and low carbon percentage. These magnetic Alloy Steel Boiler Tubes possess notable characteristics, including high ductility, corrosion resistance, and resistance to stress-related corrosion cracking. This makes them a preferred choice in diverse applications, from automotive to kitchenware and industrial equipment.

We understand that every project has unique requirements. As such, we offer the flexibility to customize our alloy steel pipes and tubes to align perfectly with your specific needs.

Alloy steels come in two primary categories: high alloy steels and low alloy steels. Low alloy steel pipes are defined by having an alloying percentage of less than 5%, while high alloy steels contain alloying elements ranging from 5% to approximately 50%.

An Alloy Steel Seamless Pipe boasts a working pressure capability approximately 20% higher than a welded pipe, a common characteristic among most alloys. This makes seamless pipes the preferred choice in applications that require higher working pressures. However, it’s essential to note that their cost is notably higher than welded pipes, reflecting their superior strength.

Alloy Steel Seamless Pipes & Tubes find their place in applications that demand moderate corrosion resistance, durability, and cost-effectiveness. These versatile components serve diverse industries.

The High Temperature Alloy Steel Boiler Pipe shines in applications where ambient temperatures soar to 500°C. This makes them ideal for challenging environments, such as drilling rigs, where they must withstand pressure differentials both inside and outside the Alloy Steel Seamless Pipe.

Products crafted from alloy steel surpass carbon steel counterparts in performance. While they offer a cost-effective alternative to stainless steel, they exhibit superior corrosion resistance when compared to carbon steel. This makes them a popular choice in various industrial applications.
