Value Collection SR07.0X3 Tool Steel Round 7 in S-7

Product Description

The VALUE COLLECTION SR07.0X3 is a decarburization-free tool steel round bar machined to a 7-inch diameter and 3-inch overall length in S-7 Hi-Shock tool steel. S-7 is an air- or oil-hardening shock-resistant grade engineered for high-impact tooling applications where toughness and resistance to chipping are critical. The decarb-free condition means the surface has been processed to eliminate the soft, carbon-depleted layer common on standard hot-rolled stock, giving machinists and tool makers a more consistent starting material without the need for extra stock removal to reach sound metal.

This round is suited for industrial tooling environments where S-7 grade is specified: die making, punch and driver fabrication, chisels, shear blades, and other impact tooling. The stock-length format makes it appropriate for single-piece blanking or low-quantity tool production runs. Machinists, tool-and-die makers, and metalworking shops working with heavy-section tooling will find this round ready to machine to near-net shape before heat treatment.

Key Features

• Decarb-free surface condition eliminates soft skin removal as a pre-machining step
• S-7 Hi-Shock grade provides high toughness and impact resistance for demanding tooling applications
• Diameter tolerance of +0.070 to +0.150 inches allows confirmation of oversize stock before finish machining
• Length tolerance of +0.250 to -0.000 inches ensures minimum usable length is met
• Weight per foot of 137.30 pounds supports material planning and setup load calculations
• UNSPSC Code 20102105 for procurement and catalog classification

Compatibility

Designed as a general-purpose decarb-free S-7 tool steel round for use in die shops, tooling departments, and metalworking facilities requiring shock-resistant stock in heavy-section diameters.

Installation Notes

Handling a 35.4-pound billet of this diameter requires appropriate lifting equipment or a second person to avoid injury during fixturing. Secure the workpiece in a lathe chuck or mill fixture rated for the stock weight before beginning any cuts. Heat treatment of S-7 steel should be performed by a qualified heat treater following the material grade specifications; improper quench media or temperature cycling can result in cracking or inadequate hardness. Follow applicable shop safety standards for machining large-diameter stock, including proper guarding and chip control.
