1Cr18Ni9Ti steel Forged Sleeves Forging Cylinder

High-Performance Alloy Steel Forgings: 17CrNiMo6 and 31CrMoV9 for Industrial Excellence

Our premium range of forged components is crafted from two exceptional alloy structural steels—17CrNiMo6 and 31CrMoV9—engineered to meet the most demanding industrial applications worldwide. These materials are selected not only for their mechanical strength but also for their ability to withstand extreme operating conditions, making them ideal for critical sectors such as automotive engineering, aerospace manufacturing, heavy machinery, and high-pressure process equipment.

The 17CrNiMo6 alloy combines carbon, chromium, nickel, and molybdenum to deliver outstanding toughness, fatigue resistance, and hardenability. It's commonly used in precision parts like forged shafts, rings, and sleeves where durability under dynamic loads is essential. Meanwhile, 31CrMoV9—a steel rich in carbon, chromium, molybdenum, and vanadium—offers superior creep resistance and thermal stability at elevated temperatures, making it a top choice for boiler components, pressure vessels, petrochemical reactors, and oil refining units subjected to intense heat and stress.

Each forging we produce—from custom-designed forged tubes and flanges to seamless ring segments and robust sleeve assemblies—is manufactured using advanced metallurgical techniques and strict quality control protocols. Whether you're sourcing durable forged steel products for power generation systems or need high-strength components for mining equipment, our facility ensures consistent microstructure uniformity, minimal internal defects, and optimal dimensional accuracy. Our expertise spans both standard and non-standard geometries, allowing us to support OEMs and contractors with tailored solutions across global markets.

These materials are frequently specified in international standards such as ASTM A182, EN 10083, and ISO 683, ensuring compatibility with global engineering specifications. The combination of alloy composition, heat treatment optimization, and precise forging methods results in enhanced wear resistance, reduced risk of premature failure, and extended service life—even in corrosive or cyclic loading environments.

Common applications include but are not limited to: turbine shafts, crankshafts, gear blanks, valve bodies, flange fittings, and high-temperature piping supports. These forged components serve industries ranging from energy infrastructure to heavy construction, where reliability and performance cannot be compromised.

Customers consistently highlight the consistency in mechanical properties, ease of machining post-forging, and long-term cost-effectiveness compared to alternative materials. Many have noted that switching to our 17CrNiMo6 and 31CrMoV9 forgings has significantly reduced maintenance cycles and improved system uptime in demanding operational settings.

Q: What makes 17CrNiMo6 suitable for automotive and aerospace use? A: Its balanced alloying elements provide excellent impact strength, machinability, and case-hardening capability—ideal for gears, axles, and landing gear components requiring high fatigue resistance.

Q: Can 31CrMoV9 be used in environments above 500°C? A: Yes—it maintains its structural integrity up to approximately 550°C, making it a preferred material for superheater tubes, pressure vessel internals, and steam generator parts in power plants.

Q: Are your forgings certified for international projects? A: Absolutely—we adhere to ISO 9001 quality management principles and can provide material test reports (MTRs), chemical analysis certificates, and mechanical property documentation upon request.
