 E355 Hydraulic steel tube, as the core transmission components of hydraulic systems in construction machinery, mining equipment, and aerospace, directly determine the safety and service life of the equipment. I. Raw Materials selections: I. Materials Science: The Foundation of High-Precision Hydraulic Tubes High-precision hydraulic tubes are made from cold-drawn seamless steel tubes (material grades: ST52.4/30CrMo/SAE 4130), with a yield strength of ≥500MPa and an elongation of ≥15%, ensuring resistance to deformation under high-pressure conditions. 2. Material Pre-treatment Process Phosphating and Saponification Treatment: Before cold drawing, the tube blanks undergo surface phosphating (ZnCaPO₄ coating) to reduce the friction coefficient. A saponification layer (sodium stearate) further lubricates, ensuring uniform wall thickness after cold drawing (tolerance ±0.1mm). II. Precision Processing Flow: Five Core Procedures 1. Cold Drawing Forming Process Die Design: Multi-stage ...
