Julong Yulong Special Steel Co., Ltd. is a professional manufacturer of high-quality forged and cast mechanical components. The company has an annual steel output of 100,000 tons, with product portfolios covering two major sectors: special steel materials and tool/die steels.
For the application of forged mechanical components, the following key points should be emphasized:
- Open-die forgings such as metallurgical rolls, crankshafts, and hydraulic cylinders are commonly made from alloy steels like 42CrMo and Cr12, offering excellent impact resistance and fatigue strength.
- Die steel blocks (e.g., H13, 718) achieve a dense, refined microstructure after forging and are widely used in plastic molding and die-casting dies.
- Various forged rounds (φ300–1200 mm) and wear-resistant parts (e.g., high-chromium cast iron hammer heads and liners) benefit from grain refinement and are free from casting defects, making them suitable for severe service conditions such as mining crushing and grinding.
To select the right forged components, it is essential to match material grades and heat treatment processes according to the equipment load, and to regularly inspect critical areas for wear and deformation. This helps extend service life and ensures safe equipment operation.
Julong Yulong Special Steel's products are widely used in automotive, petrochemical, mechanical processing, and other industries.
