This can be easily machined to an excellent finish. It also has splendid weldability. For jigs, fixtures, patterns, machine parts, stripper plates, punch pads, and die plates, it offers a real cost savings. This material is furnished ground to the same velvet finish and close size tolerance as our ground flat tool steels.

In majority of cases this will be used as received, not hardened, but if desirable can be carburized or case hardened. In carburizing a maximum depth of 1/32” hardness will be obtained if piece is held in carburizing salt at 1700 degree Fahrenheit for three hours. In case hardening with sodium cyanide a maximum depth of .006” will be obtained if piece is immersed in bath for 30 min. at 1500 degree Fahrenheit.

This Low Carbon Ground Flat Stock is ground to plus or minus .001” on thickness including 1-1/4”. Over 1-1/4” plus or minus .002”. Widths are plus .005” minus .000”. Lengths are all furnished on the plus side.
