1. Introduction to G200 440C Stainless Steel Ball

The G200 440C Stainless Steel Ball is a precision metal sphere manufactured from 440C martensitic stainless steel. This material is well known for its high carbon content, excellent hardness, and superior wear resistance.

The "G200" grade refers to the dimensional accuracy and surface tolerance of the steel ball according to international ball grading standards. While not as ultra-precise as G10 or G25 grades, G200 provides reliable performance for many industrial applications while remaining more cost-efficient.

These balls are commonly used in mechanical assemblies where moderate precision, durability, and corrosion resistance are required.

2. What Does "G200" Mean in Steel Ball Grading?

Steel balls are graded according to precision levels defined by international standards such as ABMA and ISO. The lower the grade number, the higher the precision.
