Ductile Iron Rectangular and Square Bars

Jinyo offers machining services for rectangular and square bars. A variety of sizes are available in stock, and other sizes can be customized. Most pre-milled bars are made of 65-45-12 ductile iron. Milling can be performed on one, two, three, four, five, or all six sides of the product, depending on customer requirements and applications. Other materials, such as 80-55-06, 100-70-03, and SSDI, are also available upon request, depending on the finished size.

Advantages of high-precision bar stock include:

✅ Pressure resistance: No leakage with a 1mm wall thickness under 35MPa pressure; compressive strength 1-2 grades higher than sand castings.

✅ Fatigue strength: 40% higher than sand castings, suitable for high-frequency stress scenarios.

✅ Surface treatment: Electroplating/coating/carburizing effects are superior to steel parts, suitable for complex working conditions.
