Mirror-like finish provides a bright, reflective appearance
Meets A493 specifications
The 316 stainless steel sphere has a mirror-like finish, meets American Society for Testing and Materials International A493 specifications, is Grade 100, and has a precision tolerance. The 316 stainless steel grade provides better corrosion resistance than general-purpose 304 stainless steel, especially in marine environments, due to higher nickel content and the addition of molybdenum. An austenitic stainless steel, 316 is typically nonmagnetic and can be cold worked to increase its hardness and strength while maintaining most of its formability. The mirror-like finish provides a bright, reflective appearance.
Stainless steel is an iron alloy with resistance to staining and rusting in many environments where steel would typically degrade. The chemical composition of each grade creates a grain structure that falls into one of five classes: austenitic, duplex, ferritic, martensitic, and precipitation hardening. The austenitic class contains the most formable, weldable, and corrosion-resistant stainless steel grades, but they cannot be heat treated. The duplex class offers high resistance to pitting and chloride stress corrosion cracking. Duplex grades are heat treatable and roughly twice as strong as austenitic grades. The ferritic class contains moderately formable and corrosion-resistant grades compared to other stainless steel classes, but they cannot be heat treated. The martensitic class includes some of the hardest and strongest stainless steel grades that also offer mild corrosion resistance, high hardness, and good formability. Martensitic grades can be heat treated. The precipitation-hardening (PH) class can be heat treated after fabrication to achieve some of the highest hardness ratings in stainless steel.
Tensile strength, used to indicate the material’s overall strength, is the peak stress it can withstand before it breaks. Corrosion resistance describes the material's ability to prevent deterioration caused by atmosphere, moisture, or other medium. Wear resistance indicates the ability to prevent surface damage caused by contact with other surfaces. Toughness describes the material's ability to absorb energy before breaking, while hardness (commonly measured as indentation hardness) describes its resistance to permanent surface deformation. Formability indicates how easily the material can be permanently shaped. Machinability describes how easily it can be cut, shaped, finished, or otherwise machined, while weldability characterizes the ability to be welded. Magnetism characterizes how much the material is repelled by or attracted to a magnet.

Bought 300 of these steel balls for a science experiment. They worked perfect round, smooth, shiny, stainless steel. We didn't need a high QC product with exacting dimensions, so this worked perfect.
Visually they all look the same exactly how you'd imagine.
Now that the experiment is done I have 300 stainless steal balls, ideas anyone?
Salon you ask...... yes, we use these SSTL balls in all bottles of nail polish. New bottles of polish usually have one or two such balls inside. Over the years, we have discovered that if we add an extra 4 or 5 of these small balls to each bottle, it is much easier and/or faster to shakeup the polish before each use. We will certainly order these again.
I mean what else can be said its a 316 Stainless Steel ball bearing, not like it's going to get damaged in shipping or anything. Arrived quickly and has a nice mirror finish.
