Engineering Steel is a steel that has had small amounts of one or more alloying elements (other than carbon) such as such as manganese, silicon, nickel, titanium, copper, chromium and aluminum added. This produces specific properties that are not found in regular carbon steel.
Engineering Steels are workhorses of industry because of their economical cost, wide availability, ease of processing, and good mechanical properties. Alloy steels are generally more responsive to heat and mechanical treatments than carbon steels.
Tool Steel Ground Flat Stock BO1 is a precision ground flat stock of BO1 Tool Steel.
BO1 Tool Steel is a general purpose oil-hardening tool and die steel.
Normal care in heat treatment gives good results in hardening and produces small dimensional changes. O1 has good abrasion resistance and sufficient toughness for a wide variety of tool and die applications.
When properly annealed, O1 has a machinability rating of 90 when compared to a 1% Carbon Steel rated at 100.
When oil quenched from the proper hardening temperature, this grade can be expected to expand approximately .0015 in. per in.
