Alloy Steel for the Automotive Industry
In the automotive industry, you never want to settle for anything less than the best. That’s precisely why Pennsylvania Steel uses top-grade alloy steel, called Flexor®, to outperform the rest. Developed with proprietary chemistry and stringent processes, Flexor® provides reliable performance in even the toughest automotive conditions.
Introducing Flexor®: A Proven Solution for Automotive Applications
Flexor® is a low-alloy steel that we’ve engineered to exceed traditional automotive materials in resistance, hardness, and strength.
Unlike standard grades, Flexor® allows for exceptional dimensional stability during both machining and heat treatment. This makes this particular alloy steel ideal for parts like crankshafts, axles, transmission parts, and suspension systems.
Pennsylvania Steel has developed Flexor® to deliver dual-property capability, which includes hard case surfaces with tough, ductile cores, without sacrificing machinability. The controlled chemistry we use guarantees consistency across all production runs. Plus, its enhanced hardenability supports deeper heat treatment whenever necessary.
Here’s what else our proprietary alloy steel for automotive industries has to offer.
Meeting the Needs of Modern Powertrain and Chassis Design
One of the biggest benefits of our Flexor® steel is its ability to meet the high-performance needs of modern-day powertrains and chassis.
Pennsylvania Steel has expertly crafted Flexor® to align with the evolving demands of the automotive industry, as strength-to-weight ratios and material integrity are crucial. Its unique metallurgical composition supports the precise performance that you often see in today's chassis and powertrains.
Flexor® offers predictable behavior under stress, which can be extremely beneficial when considering the torque-transmitting components that are constantly under stress. Having this kind of predictability allows for tight control over tolerances and deformation – even after extensive use. Truly, this type of alloy steel for the automotive industry could not be better suited for the next generation of drivetrains and suspension systems.
Flexor® vs. ASTM A370 Automotive Alloy Steel Standards
While ASTM A370 automotive alloy steel standards outline the testing procedures for mechanical components, Flexor® always delivers results that surpass typical expectations for automotive-grade alloy steels.
Engineered for elevated tensile and yield strength, Flexor® illustrates superior performance in the most critical benchmarks – this includes elongation, impact resistance, and hardness retention.
According to ASTM A370 automotive alloy steel standards, Flexor® enables deeper and more uniform heat treat response than conventional alloy steels. Thus, engineers who require tighter control, minimized variance, and better fatigue characteristics will likely find Flexor® to be the best, most reliable upgrade around.
You can check out our various case studies to see just how successful Flexor® has been since its inception.
Precision Machining and Manufacturing Flexibility
Finally, our team has designed Flexor® with efficiency in mind. This alloy steel for the automotive industry offers clean machinability that reduces cycle times and tool wear. Flexor® maintains its uniform microstructure and dimensional reliability whether you’re producing prototypes or scaling up to full production.
You can find this proprietary steel available in rounds, flats, blocks, and even custom-cut billets, as the material integrates seamlessly into automated machining environments. The metal’s properties allow for a more straightforward adaptation to various heat treatments and surface hardening operations.
So, when you need flexibility without compromising integrity, Flexor® is the way to go.
