304 and 304L austenitic stainless steel are widely used for precision steel balls and fluid components. The core difference lies in carbon content. This article analyzes their distinctions in weldability, intergranular corrosion resistance and mechanical properties, providing professional material selection solutions for diverse industrial working conditions.

Hollow steel ball quality depends largely on manufacturing technology. This article systematically analyzes four mainstream forming processes including welding, water swelling, CNC pressing and precision hydraulic forming, comparing their structural features, accuracy performance and applicable industrial scenarios for precision machinery and fluid equipment applications.

Steel shot abrasive is an essential spherical consumable for precision steel ball finishing and surface strengthening. Made via centrifugal atomization and precision heat treatment, it optimizes steel ball surface roughness, eliminates stress concentration, and forms a residual compressive stress layer to greatly improve wear resistance and fatigue durability of high-end precision steel balls.

Metallurgical micro-inspection is the core quality control process for high-end precision steel balls. This article introduces standardized detection principles and procedures of steel ball microstructure, surface decarburization and IGO intergranular oxidation, complying with ISO 3887 standards to eliminate hidden heat treatment defects and prevent early bearing failure.

Rockwell and Vickers hardness testing form a complementary dual quality control system for precision steel balls. Rockwell testing supports efficient batch mass inspection, while Vickers testing provides high-precision micron-level defect detection. The dual-inspection mechanism ensures stable mechanical performance and heat treatment quality for bearing and new energy steel balls.

Rockwell and Vickers hardness tests are two mainstream non-destructive inspection methods for precision steel balls. This article compares their similarities, testing principles, accuracy gaps and application scenarios, illustrating Feige Steel Ball’s dual-standard hardness quality control capability.

Vickers hardness testing is a high-precision inspection method for precision steel balls, capable of detecting substrate and micro hardened layer hardness. Adopting GB/T4340.1 standard, it effectively identifies gradient hardness defects and ensures stable mechanical performance for new energy and precision bearing steel balls.

Steel ball hardness determines the wear resistance and fatigue life of high-end bearings and new energy transmission parts. Rockwell hardness testing serves as the core quality inspection method for heat treatment evaluation. This article introduces standardized HRC testing procedures and professional hardness inspection capabilities of Feige Steel Ball.

CCD scanning machine vision technology has replaced traditional manual inspection as the core full-inspection process for high-end precision steel balls. It achieves 360° dead-angle-free surface defect detection as low as 0.02mm, effectively reducing bearing premature failure and ensuring stable surface quality for new energy and bearing steel balls.
