Stainless steel products that require both cold heading and machining operations have been notoriously troublesome—because stainless alloys that machine easily don't lend themselves to cold forming and vice versa. Carpenter Technology Corp. (www.cartech.com) recently developed an alloy intended to support cold forming and various machining operations, including drilling, slotting, and broaching. Called 302HQ-FM® stainless (S30431), this stainless grade offers a low work hardening rate to foster cold forming operations. At the same time, it has a machinability rating approaching that of Type 303 stainless.
Everyone has had the experience of trying to scrape the last of the peanut butter or mayonnaise from the bottom of a glass jar without getting your hand sticky. Inventor Ron Jidmar thinks he has a solution to all of that nonsense with a flexible jar design that can be squeezed with one hand to lift contents from the bottom to the top of a jar or container, leaving the other hand free to scoop the contents out cleanly.
