CNC Precision Turned Nitrided SAE 1045 Steel Parts With High Hardness

Advantages of Nitrided SAE 1045 Steel in Industrial Applications

High Strength & Versatility: SAE 1045 steel, a reliable medium-carbon structural steel, delivers balanced mechanical properties—good tensile strength, impact resistance, and machinability. It performs well under heavy loads, continuous stress, and repeated use, making it ideal for components like shafts, gear blanks, and mechanical fittings, while its adaptability extends to diverse industrial needs.

• Enhanced Performance via Nitriding: Nitriding boosts SAE 1045 steel’s surface hardness (up to 60+ HRC) while retaining core toughness, balancing wear resistance with durability. This treatment benefits high-friction parts (bearing surfaces, cam components) but also enhances longevity across broader applications, from high-stress machinery to general industrial tools.

• Precision Machinability: SAE 1045 steel’s excellent machinability supports tight tolerances via CNC turning, milling, and more. Whether post-nitriding or for untreated parts, it meets precision needs for complex geometries—from intricate fittings to large-scale components—with consistency that applies to other materials too.

15+ Years of Experience on CNC Machining:

JINGXIN, with over 15 years of experience in custom CNC precision machining services and based in Dongguan City, China, leverages advanced CNC technologies and surface treatment expertise to excel in nitrided SAE 1045 steel parts—with capabilities that extend far beyond.

Our professional team adopts reasonable manufacturing processes, solutions, and workmanship to deliver high-quality, one-stop custom CNC precision machined parts. We boast broad material expertise, handling not only SAE 1045 steel but also stainless steels, aluminum alloys, iron, and engineering plastics, applying the same precision to CNC turning, milling, and multi-axis machining across diverse materials.

Comprehensive precision control is a cornerstone of our services, achieving tight tolerances (±0.01mm or finer) across all processes to ensure seamless integration—whether for nitrided 1045 components or precision parts in other materials—backed by rigorous quality checks for fit and performance. Our surface treatment capabilities are equally versatile: beyond the specialized nitriding process for SAE 1045 steel, we master plating, anodizing, and heat treatments, tailoring finishes to meet specific needs for corrosion resistance, hardness, or aesthetics across industries.

From high-wear industrial parts to precision components for automotive, machinery, and more, we provide tailored solutions that match the unique demands of each project. By combining deep expertise in SAE 1045 steel and nitriding with a full range of machining capabilities, JINGXIN stands as a versatile partner, ready to meet not just specialized needs for high-hardness components, but the breadth of precision manufacturing requirements across industries.
