No Heat Treatment Steel Ball

The "carbon steel" used for these balls is almost always a low carbon steel, such as AISI 1010, Q235, or 1015. The low carbon content (typically less than 0.20%) is key:

• Low Hardenability: These steels cannot be significantly hardened by heat treatment. Attempting to quench them would have little effect. This makes the "no heat" process a logical and cost-effective choice.

• Good Formability: Low carbon steel is ductile and easy to form into a spherical shape through processes like cold heading or forging.

These balls are not used for applications requiring high strength, precision, or wear resistance (like bearings). Instead, they are ideal for:

• Check Valves and Float Valves: Their softness allows them to form a tight seal against a seat to control fluid flow.

• Material Handling and Conveyor Systems: Used as low-cost, durable balls in conveyors or as grinding media in ball mills for crushing softer materials (though hardened balls are preferred for most milling).

• Draftsman's Hammers (Tap Blocks): The soft steel will not damage tools when used for tapping or positioning.

• Decorative Applications: As components in furniture, art, or fencing.

• General Purpose Use: Where a simple, inexpensive metal ball is needed for a non-precision application, such as a plug, weight, or spacer.
