This Standard replaces GB/T 3077-1999 "alloy structure steel". Compared with GB/T 3077-1999, the main technical changes of this Standard are as follows. GB/T 702 Hot-rolled steel bars - Dimensions, shape, weight and tolerance GB/T 908 Forged bars - Dimensions, shape, weight and tolerance Gb3077 - SlideShareJun 18, 2015 · Gb3077 1. Foreword The standard has revised GB/T 3077-1988 The Technical Conditions of Alloy Structure Steel. There have been some changes in this nationals standard over its previous edition in the following technical aspects:- Change the name of the standard to Alloy Structure Steel; - After consultation between the two sides of supply and demand, the bar stock of which the P11,P22,P91,AISI8630,SCM440,AISI4145H HOT ROLLED SPECIAL STEEL ROUND BAR No Category Grade Sizes Specifications / Standards Application 1 A105S20Cr2545C45EC45RC45RCrS45CBS45CrS45Ti 75350 EN10083-2 Carbon constructional steel Technical protocol Widely used to produce heavy load crankshafts, connecting rods, crank pins, gears, rollers, etc. 2 Q345BQ345EA350LF2S355J2 75350 GB
