What are Alloy 20 Bars?
Alloy bars are essential in various industrial and commercial applications that require a high degree of corrosion resistance, strength, and durability. One of the most popular types of alloy bars in the market today is the Alloy 20 Bar. This alloy has become a preferred material for various industries such as chemical processing, food production, and pharmaceuticals because of its unique properties.
Alloy 20 Bars is a nickel-chromium-molybdenum steel alloy with additions of copper and tungsten. The alloy contains 20% chromium and 34% nickel, which makes it highly resistant to corrosion caused by organic acids, sulfuric acid, and chlorides. Its unique composition also offers exceptional resistance against stress-corrosion cracking and pitting.
Properties of Alloy 20 Bars
Alloy 20 bars offer several desirable properties suitable for both high and low-temperature applications. It boasts excellent mechanical properties such as high tensile and yield strength, with a tensile strength range of 80-100 Ksi. It also offers good elongation and was designed for maximum toughness and ductility. Alloy 20 bars exhibit exceptional resistance to intergranular corrosion, crevice corrosion, and corrosion fatigue, making it an ideal alloy for harsh environments.
Applications Alloy 20 Bars
Alloy 20 bars have found applications in various industries such as chemical processing, food processing, and beverage production. Specifically, its corrosion resistance property has made it ideal for handling sulfuric acid, acetic acid, phosphoric acid, and other chemical processing environments. In the food processing industry, Alloy 20 bar is commonly used to handle food-grade chemicals like citric, formic, and lactic acids. The pharmaceutical and biotech industries also use Alloy 20 Bars for processing chemicals that require hydrochloric and sulfuric acids.
To ensure optimal performance, it’s essential to properly maintain Alloy 20 bars. Regular inspections, cleaning, and corrosion control practices should be implemented to maximize their lifespan. When welding the bars, special care should be taken to avoid distortion and cracking due to the high heat required during welding. Post-weld cleaning and heat treatment are also recommended to maintain the alloy’s corrosion resistance.
