  1.  BLOG April 22, 2025 EN19 Flat Bar The EN19 Flat Bar is a solid rectangular shape. This steel is also known as 4140 steel. It contains important ingredients such as chromium, molybdenum and carbon. These elements improve steel strength, hardness and wear resistance. The EN19 bar is designed for use in areas where high tensile strength and good machining are required. It helps in many industries. The shape of a ?at bar helps in easy machining, welding, and cutting. EN19 Bars are cut from EN19 steel plates or made through rolling methods. The quality of the ?at bar

  2. depends on the raw material and the process used. EN19 Flat Bar is one of the most preferred choices for engineers and industries where performance matters. Uses of EN19 Flat Bar The EN19 ?at bar can be used in many ways in industries. Here are some of the most common uses: Construction of gear, shaft and axle Machine components that handle stress and load Automotive parts like Crankshaft and Connecting Rods Agricultural Machinery and Equipment Heavy tools and construction parts Fixtures, jigs, and dies Engineering components used in railways and aviation The strength and wear resistance of EN19 Flat Bar make it suitable for these applications. It is also used in oil and gas sectors and industrial machinery where heat and pressure are high. Chemical Composition of EN19 Flat Bar Element Percentage (%) 0.36 – 0.44 Carbon (C) 0.70 – 1.00 Manganese (Mn) 0.90 – 1.20 Chromium (Cr) 0.15 – 0.30 Molybdenum (Mo) 0.10 – 0.35 Silicon (Si) Max 0.035 Sulphur (S) Max 0.035 Phosphorus (P) Each element in this composition plays a special role. Carbon improves hardness. Chromium helps in corrosion resistance. Molybdenum increases strength. Manganese and silicon support toughness. Mechanical Properties of EN19 Flat Bar

  3. Property Value 850 – 1000 MPa Tensile Strength 680 MPa (min) Yield Strength 13% (min) Elongation 55 Joules (C harpy V) Impact Value 248 – 302 Hardness (HB) Mechanical properties show how the EN19 Flat Bar will perform under di?erent loads and pressures. High tensile and yield strength mean the bar can carry heavy loads. Elongation shows it can bend slightly without breaking. Impact value helps in shock applications. Heat Treatment Process of EN19 Flat Bar Heat treatment changes the structure of the steel. It makes the EN19 Flat Bar strong and hard. Here is the general heat treatment process: 1. Hardening: Heat the ?at bar to around 850°C – 880°C. Then, quench it in oil to lock the hardness. 2. Tempering: After hardening, tempering is done at 400°C – 650°C. This step reduces internal stress and increases toughness. 3. Annealing: Heat to 680°C – 700°C and allow it to cool in a furnace. This softens the bar for easier machining. 4. Stress Relieving: Heat to 600°C – 650°C after machining. Cool slowly to reduce internal stress. Heat treatment helps match the EN19 Flat Bar to speci?c needs. For example, a part needing more ?exibility will be tempered longer. Size and Length Availability EN19 Flat Bars are available in many sizes. This allows easy selection based on application. Here are common size ranges:

  4. Parameter Range 20 mm to 300 mm Width 5 mm to 100 mm Thickness 6 meters (customization) Standard Length Custom sizes and cut-to-length options are available. This is helpful when the bar is used in machine building or construction. Some industries need exact measurements, and custom cutting saves time and cost. Why Choose Alloy Carbon Steel for EN19 Flat Bar? Alloy Carbon Steel is a trusted supplier of EN19 Flat Bars. Here is why people prefer them: They supply EN19 Flat Bars that match industrial standards. They o?er bars with proper heat treatment. All bars are checked for size accuracy. They provide custom sizes based on project requirements. Delivery is on time and handled with care. They share test certi?cates for trust and reliability. Choosing Alloy Carbon Steel helps avoid delays and poor material. You get consistent quality and good support. If you are working on high-pressure machinery or heavy-duty equipment, they are a reliable partner. Ultrasonically Tested and Approved EN19 Flat Bars EN19 Flat Bars from Alloy Carbon Steel are ultrasonically tested. This test checks the inside of the bar. Ultrasonic machines send sound waves through the bar. If there are any cracks or gaps, the machine will detect them. Ultrasonic testing ensures the bar has no hidden problems. This test is important for parts that carry load or rotate. Bars that pass this test are approved for use in critical jobs. Each EN19 Flat Bar gets a quality certi?cate after testing. This gives con?dence to the buyer. It shows the material is strong and safe. Companies that make machines, vehicles,

  5. or tools can trust these bars. Extra Applications of EN19 Flat Bar Besides the uses already discussed, here are more applications: Oil?eld parts Power plant equipment Aircraft landing gear components Forging dies Hydraulic machinery parts These applications show the ?exibility of EN19 Flat Bars. They are strong and easy to shape or machine. That makes them helpful in many technical and industrial setups. Machining and Welding EN19 Flat Bar You can easily machine EN19 Flat Bar using standard tools. However, for the best results, make sure to heat-treat the bar before machining. This step helps shape the bar smoothly and prevents cracking during the process. Welding EN19 Flat Bar is also possible, but it requires careful handling. Always preheat the bar before welding and apply post-heating afterward. These steps reduce the chances of cracks or stress buildup. Additionally, use low hydrogen electrodes to improve weld quality and avoid welding defects. When you follow the right methods, EN19 Bars perform well in both machining and welding, making your project smoother and more reliable. Storage and Handling of EN19 Flat Bar Store EN19 Flat Bars in dry, covered areas to protect their quality. Always keep them away from moisture, as rust or corrosion can reduce their strength and performance. To maintain their shape, place the bars on wooden blocks or racks instead of directly on the ground. When handling these bars, avoid dropping or dragging them, as this can cause damage. Instead, use proper lifting tools to move them safely and smoothly. This not only prevents wear but also makes the process more e?cient.

  6. Conclusion EN19 Flat Bar is a strong and widely used steel product. It comes from chromium- molybdenum carbon alloy steel and performs well in tough conditions. Because of its strength, it easily handles high loads and pressure. When you apply proper heat treatment, the EN19 Flat Bar becomes even more powerful and dependable.
