Made to Grades 50, 60, 70 and 80 the grade designating the yield strength. Chapel Steel stocks in Grade 80 up to 3/4 , Grade 70 over 3/4 to 1 and Grade 60 over 1 to 1-1/2. Request Info Milling inserts and grades for hardened steelGC1010 is a PVD-coated grade for light roughing to finishing operations. With its exceptional resistance to plastic deformation, thermal cracking, and other types of wear, this grade can withstand long periods of time in cut and is suitable for machining hardened steel from 36 HRC and higher.
