XM19 Round Bars are advanced stainless steel alloy bars designed for superior strength, durability, and corrosion resistance, making them essential in industries requiring exceptional mechanical properties. These bars are engineered to excel in harsh environments, with high resistance to oxidation, wear, and stress corrosion cracking. XM19 Round Bars are ideal for critical applications in sectors like aerospace, chemical processing, marine, power generation, and manufacturing. The production process involves melting premium raw materials and forging them into precise bars that ensure reliability and outstanding performance in extreme conditions.

The alloy composition of XM19 Round Bars includes a high concentration of nitrogen, chromium, and molybdenum, which provide exceptional protection against corrosion and oxidation. These bars offer superior tensile strength, enhanced toughness, and excellent wear resistance, making them ideal for heavy-duty applications. Available in diameters typically ranging from 6mm to 200mm, XM19 Round Bars can be customized in length and diameter to meet specific application needs. The bars adhere to industry standards such as ASTM A276 and ASTM A479, guaranteeing consistent quality and excellent performance across a wide range of applications.

XM19 Round Bars come in a variety of surface finishes including black, bright, and polished, catering to different industrial requirements. Additionally, centerless ground bars are available, offering precise tolerances, enhanced straightness, and improved machinability. This makes XM19 Round Bars an ideal choice for applications that require tight dimensional control and smooth surfaces. Their excellent mechanical properties and corrosion resistance ensure these bars deliver long-lasting performance, even in the harshest environments, minimizing the need for frequent maintenance or replacements.

XM19 Round Bars find wide use in industries such as aerospace, marine, chemical processing, and power generation, where high strength and corrosion resistance are critical. They are commonly used for producing components like shafts, fasteners, valves, and other structural parts exposed to high temperatures, corrosive substances, and mechanical stress. Thanks to their excellent wear resistance and ability to withstand extreme operating conditions, XM19 Round Bars provide reliable performance in some of the most demanding environments, making them a trusted material for applications where durability and strength are paramount.

We supply XM-19 Round Bars in a wide size range: 3mm to 600mm diameter and custom lengths up to 12m, Leading XM-19 Round Bar Manufacturer and Exporter.
