There are savings up to 60% because this is a low carbon steel and furnished in 24" lengths. This means that you get one-third more steel at less cost. • Ideal for a wide variety of parts that don't require more expensive heat treated steels, such as stripper plates, jigs, fixtures, machine and component parts, templates, etc. • This steel can be carburized or case hardened. After hardening, its physical properties, especially tensile strength, yield point, and Brinell hardness, are substantially higher. • NOTE:Thicknessesof1/8"andunderaremadefromAISI1010material • Starrett uses its own ground flat stock for many of its precision tool parts Precision Ground Fla t Stock Specifica tions Furnished in 24" lengths, ground straight and parallel. Analysis Starrett 498 Low Carbon Precision Ground Flat Stock is a .20 carbon fine-grained, milled steel, which can be carburized or case hardened. Very similar to AISI 1018. Hea t Trea tment For many applications, stock can be used unhardened. However, if surface hardening is desired, it can be carburized or case hardened. If carburized, a case of 1/32" will be obtained if the steel is held in carburizing salt at 1700º F for three hours. 498 Low Carbon Precision Ground Flat Stock Thickness Width 24" Length 1/16" 1/2" 54866 3/4" 54867 1" 54868 1-1/4" 54869 1-1/2" 54870 2" 54871 2-1/2" 54872 3" 54873 3-1/2" 54874 4" 54875 5" 54876 6" 54877 8" 54878 10" 54879 12" 54880 3/32" 1/2" 54881 3/4" 54882 1" 54883 1-1/4" 54884 1-1/2" 54885 2" 54886 2-1/2" 54887 3" 54888 3-1/2" 58285 4" 54889 5" 54890 6" 54891 8" 54892 10" 58286 12" 58287 498 Low Carbon Precision Ground Flat Stock Thickness Width 24" Length 1/8" 1/2" 54893 3/4" 54894 1" 54895 1-1/4" 54896 1-1/2" 54897 2" 54898 2-1/2" 54899 3" 54900 3-1/2" 54901 4" 54902 5" 54903 6" 54904 8" 54905 10" 54906 12" 54907 5/32" 1/2" 54908 3/4" 54909 1" 54910 1-1/4" 54911 1-1/2" 54912 2" 54913 2-1/2" 54914 3" 54915 3-1/2" 58290 4" 54917 5" 54918 6" 54919 8" 58291 10" 58292 12" 58293 498 Low Carbon Precision Ground Flat Stock Thickness Width 24" Length 3/16" 3/16" 57247 1/2" 54921 3/4" 54922 1" 54923 1-1/4" 54924 1-1/2" 54925 2" 54926 2-1/2" 54927 3" 54928 3-1/2" 54929 4" 54930 5" 54931 6" 54932 8" 54933 10" 54934 12" 57248 1/4" 1/4" 57249 1/2" 54935 3/4" 54936 1" 54937 1-1/4" 54938 1-1/2" 54939 2" 54940 2-1/2" 54941 3" 54942 3-1/2" 54943 4" 54944 5" 54945 6" 54946 8" 54947 10" 54948 12" 54949 563 starrett.com F la t S tock and D rill R od
