Suzhou Krosino Mechatronic Technology Co., Ltd. specializes in the production of high-performance mechanical components through our advanced CNC Lathe Turning Services. Engineered for corrosion resistance, superior fatigue strength, and stringent dimensional accuracy, our 304 Stainless Steel Shaft Parts are manufactured to meet the exact technical requirements of global OEM procurement managers. By utilizing stable turning environments and specialized carbide tooling, we ensure high surface integrity and precise geometric tolerances for demanding industrial applications.
Machining SUS304 stainless steel presents unique challenges, particularly regarding tool wear and work hardening. Our facility overcomes these issues by deploying state-of-the-art multi-axis CNC turning centers equipped with high-pressure coolant systems and rigid, vibration-dampened tool turrets. This setup allows for continuous, high-efficiency machining that maintains perfect coaxiality between journals and threaded sections, providing reliable mechanical spare parts that are built to perform under harsh environmental conditions.
Our lathes execute single-point threading and journal turning with exceptional pitch control. This ensures that all CNC Machining Parts fit precisely during assembly, eliminating binding or excessive play in mechanical drive systems.
Focusing on SUS304 and other high-grade industrial materials, we prioritize maintaining the structural and anti-corrosive properties of the alloy through our Precision CNC Machining workflow, ensuring durability in demanding environments.

Q1: Why is SUS304 the preferred material for stainless steel shafts in many industrial applications?
SUS304 provides an excellent balance of corrosion resistance, mechanical strength, and weldability. It is highly resistant to oxidizing acids and atmospheric corrosion, making it ideal for shafts that must function in diverse, often humid or chemically exposed, industrial settings. While not as hard as heat-treated martensitic grades, its consistent austenitic structure offers superior toughness and resistance to sudden failure under stress.
Q2: What is the benefit of passivation for turned 304 stainless steel parts?
Passivation is a critical secondary process that removes free iron from the surface of machined 304 stainless steel. During the turning process, microscopic iron particles from cutting tools can become embedded in the surface of the part. If left untreated, these particles act as initiation sites for rust. Passivation chemically dissolves these contaminants and promotes the formation of a dense, protective chromium-oxide layer, drastically enhancing the natural corrosion resistance of the finished mechanical spare part.
