How Do You Test the Strength of Forged Parts?

Forged steel parts are renowned for their exceptional strength and durability, making them essential in industries like mining, automotive, energy, and construction. At WALKSON, a leading supplier of high-quality steel closed-die forging parts based in China, we understand that strength isn’t just a promise—it’s a measurable guarantee. But how exactly do you test the strength of forged parts? Let’s explore the rigorous methods that ensure these components can withstand the toughest conditions.

1. Tensile Testing: Measuring Ultimate Strength

One of the most common ways to test the strength of forged parts is through tensile testing. This process involves pulling a sample of the forged steel until it breaks, measuring its ultimate tensile strength (UTS) and yield strength. At WALKSON, we use advanced tensile testing machines to ensure our closed-die forgings meet standards like ASTM E8. This test reveals how much force our parts can endure before deforming or failing—critical for applications like heavy machinery or structural components.

2. Hardness Testing: Assessing Resistance to Wear

Hardness is a key indicator of a forged part’s ability to resist wear and indentation. Methods like Rockwell, Brinell, and Vickers hardness testing are employed to evaluate this property. WALKSON’s forged steel parts, produced in our state-of-the-art facilities in China, undergo precise hardness tests to confirm they meet specifications such as ISO 6508. A harder surface means better durability, which is why our forgings excel in high-wear environments like mining equipment.

3. Impact Testing: Evaluating Toughness

Strength isn’t just about resisting steady loads—it’s also about handling sudden shocks. Impact testing, such as the Charpy or Izod test, measures a forged part’s toughness by striking it with a weighted pendulum. This is especially important for parts used in cold climates or dynamic applications. WALKSON adheres to standards like ASTM E23, ensuring our closed-die forgings can absorb energy without fracturing, making them ideal for demanding industries worldwide.

4. Fatigue Testing: Ensuring Long-Term Performance

Forged parts often face repeated stress cycles, such as in rotating shafts or engine components. Fatigue testing simulates these conditions by subjecting the part to thousands or millions of stress cycles until it fails. This helps determine its fatigue limit—the maximum stress it can endure over time. At WALKSON, we test our steel forgings to ensure they exceed fatigue requirements, providing reliable, long-lasting performance for our clients.

5. Non-Destructive Testing (NDT): Checking Internal Integrity

Strength isn’t just about the surface; internal flaws like cracks or voids can compromise a part’s performance. Non-destructive testing methods, such as ultrasonic testing, magnetic particle inspection, and radiographic testing, allow us to inspect the internal structure without damaging the forging. WALKSON’s commitment to quality means every closed-die forging undergoes NDT per standards like EN 10228, ensuring flawless strength from the inside out.

6. Metallographic Analysis: Examining the Microstructure

The strength of forged steel lies in its refined grain structure, a benefit of the closed-die forging process. Metallographic analysis involves examining a polished sample under a microscope to verify that the microstructure is uniform and free of defects. WALKSON’s expert metallurgists in China use this technique to confirm that our forgings achieve optimal strength, aligning with industry benchmarks like ASTM E112.

Why Testing Strength Matters

Testing the strength of forged parts isn’t just a technical exercise—it’s a commitment to safety and reliability. A weak forging can lead to equipment failure, costly downtime, or even catastrophic accidents. At WALKSON, we take pride in supplying high-quality steel closed-die forgings that pass every strength test with flying colors. Our rigorous testing processes ensure that our parts deliver unmatched performance, whether they’re used in a mining drill in Australia or a wind turbine in Europe.
