Fasteners, Metals and Plastics - Ground Flat Stock 4142 Prehardened Oversize


Ground Flat Stock - Prehardened (4142) - 1" Thick - 18" Lengths - Oversize
Click Here for more information or to order
All Ground Flat Stock is 100% free of decarburization on all six sides and can be heat treated immediately without further metal removal. Thickness and width are horizontally ground to a maximum finish of 35 Ra.

All tool steel analysis (O-1, A-2, A-6, D-2, S-7, & M-2) are supplied in the annealed steel condition. Close control assures complete spheroidization throughout. The low-carbon analysis (Low Carbon) is supplied with pearlitic microstructure. Our new prehardened grade (4142) is made from alloy steel & prehardened to Rc 28-32.

All Ground Flat Stock is produced from cross-rolled sheet or plate, assuring a more homogeneous structure and finer grain size than other types. Furthermore, the cross-rolling process significantly enhances toughness of the product and increase tensile strength in the transverse direction.

All ends of Ground Flat Stock are precisely cut and deburred to insure excellent yields and handling safety. Thickness 3/16" and up are cold sawed, while lighter sections are sheared.


4142 PRE-HARDENED
Pre-Hardened Ground Flat Stock is a modified prehardened alloy steel with a Brinell hardness of 261-321 (Rc 28-32). It is normalized and tempered in a machinable condition of approximately 85% of a 1.0 carbon steel. It is useful in applications requiring a lower hardness and less wear resistance than a fully heat treated tool steel, but can be flame-hardened where a high hardness is desired.
