While “pipe” and “tube” are often used interchangeably, they have distinct meanings in engineering and manufacturing, particularly in terms of sizing and application. Pipes are primarily used for fluid conveyance, while tubes are more versatile and can be used in structural applications.

Rockhard 450 Plate is a type of high-strength, wear-resistant steel plate designed for demanding applications that require excellent durability and impact resistance. Key Features: High Hardness: Typically has a hardness of around 450 HBW, making it suitable for moderate to heavy wear applications. Wear Resistance: Engineered to withstand abrasive environments, it is ideal for industries where components are exposed to high wear and tear. Toughness: Balances hardness with good impact toughness, allowing it to perform well under dynamic loads. Weldability: Designed for easy fabrication, including welding and machining, which facilitates customization for various applications. Thickness

EN32A is a high quality low carbon steel .After forming ,carburizing or nitriding process and quenching or other heat treatment, a structural part with wear-resistant surface and tough core can be achieved.
