In modern automotive safety technology, ABS (Anti-lock Braking System) has become standard equipment. It effectively prevents wheel lock-up, ensuring directional stability during emergency braking, significantly shortening braking distance, and improving driving safety. Especially in the commercial

What Is POM? Why POM Balls = Polyoxymethylene Balls?Polyoxymethylene (POM), commonly called Acetal or POM resin, is a high-crystallinity engineering thermoplastic with the trademark name Delrin® (DuPont), Celcon®, Ultraform®, Duracon®, etc. POM balls are manufactured from 100% virgin POM resin throu

What Are Plastic Balls?Plastic balls are spherical objects made from various polymer materials, designed for use in mechanical, industrial, and functional applications. Unlike toy balls, these are often precision-engineered to meet strict tolerances for size, shape, and material properties. They com

Say Goodbye to Wear and Tear! How 420C Stainless Steel Balls Achieve Ultra-High Hardness HRC55+ Through Advanced Quenching ProcessIn precision bearings, medical devices, valves, pumps, cosmetic roll-on bottles, and high-end dispensing systems, the wear resistance and hardness of stainless steel ball

In precision bearings, medical devices, valves, pumps, cosmetic roll-on bottles, and high-end dispensing systems, the wear resistance and hardness of stainless steel balls directly determine product lifespan and performance. Traditional stainless steel balls (such as standard 420 or unoptimized 440C

1. What’s the difference between 420C and regular 420 stainless steel balls?420C is an upgraded version of 420 stainless steel. The key difference is the higher carbon content (0.95–1.20% in 420C vs. ~0.15–0.40% in 420). After heat treatment, 420C reaches HRC 50–58 (typically 52–55), offering signif

Aluminum Oxide Balls vs. Stainless Steel Balls: Which is More Durable in High-Temperature Environments?In industrial applications ranging from precision bearings and ball valves to aerospace components and high-performance grinding media, the choice of ball material under extreme temperatures can ma

GCr15 bearing steel balls 4.7625mm/6.35mm/9.525mm: High-precision steel balls preferred for motorcycle thrust bearings

How Corrosion Resistant Are 420 Stainless Steel Balls?

1. Chemical Composition: The DNA of 440C Stainless Steel BallsThe foundation of 440 stainless steel ball strength begins with its high-carbon martensitic alloy—specifically AISI 440C, the hardest and most wear-resistant grade in the 440 family (440A, 440B, 440C).
