Product Description

The 302 stainless steel sphere has a mirror-like finish, meets American Society for Testing and Materials International ASTM A493 specifications, is Grade 100, and has a precision tolerance. The 302 stainless steel grade has higher carbon content than general-purpose 304 stainless steel, providing greater strength and better toughness. An austenitic stainless steel that is one of the 18-8 grades, 302 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.

I use them as agitators in little pots of paint (Privateer Press Paints, if you must know). Since they're a) spheres and b) stainless steel, I can only rate them perfectly.

I'm no expert, but I didn't expect 302 stainless steel to be magnetic. The ten 7/8" balls that I just recieved are definately attracted when placed near a magnet. Makes me question the quality control and if I recieved what I paid for. Buyer be warned.

These little guys are exactly as described. I haven't gotten out any really precise calipers or anything to see if they are precise but they have worked well in everything I've used them for. They haven't rusted at all and they are pretty cheap.

I actually got these to drop into inks and paints (to help agitate them when I shake them up). This is a perfect, neutral size that works for many products (from 16/32 oz bottles, to dropping a single ball into a waterbrush pen).
