2014 10 27 nbsp 0183 32 F1554 Grade 55 anchor bolts are not always weldable The weldability of Grade 55 is a supplemental requirement referred to as S1 which must be specified According to the ASTM F1554 specification under section S1 1 This supplemental section by chemical composition restrictions and by a carbon equivalent formula provides assurance of weldability 2010 2 24 nbsp 0183 32 Welding of High Strength Bolts to Carbon Steel Plates By waccobird Date 02 11 2010 17 50 PA Everything I have seen says that they are not made to weld A325 Structural Bolts Steel Heat Treated 120 105 ksi Minimum Tensile Strength That being read you would have to develop a procedure and have it approved by the EOR 2020 11 8 nbsp 0183 32 ASTM F1554 Grade 105 is a special high strength rod grade and generally should be used only when it is not possible to develop the required strength using larger Grade 36 or Grade 55 rods Unless otherwise specified anchor rods will be supplied with unified coarse UNC threads with a Class 2a tolerance as permitted in ASTM F1554 While ASTMAllied Bolt and Screw carries both F1554 and ASTM A193 Grade B7 Threaded Rods Even though ASTM A193 Grade B7 has a higher tensile strength they cannot be substituted A193 Grade B7 has a minimum tensile strength of 125 2021 3 9 nbsp 0183 32 All thread rod commonly referred to as fully threaded rod redi rod F1554 Grade 36 F1554 Grade 55 F1554 Grade 105 SAE J429 Grade 2 SAE J429 Grade 5 GR 4 8 thread stud zinc 8 8 high strength square bolt black oxide Spring steel single wire R pin

ASTM F1554 is an anchor bolt specification developed by the American Society for Testing and Materials that specifies straight bent headed or headless anchor bolts and fully threaded rod It replaces ASTM A307 Grade C The F1554 specification is used in construction related projects such as commercial developments structural supports and residential developments F1554 Anchor bolts conform to the ASTM F1554 specification that covers hooked headed and threaded anchor rods in three strength grades 36 55 and 105 The grade designation corresponds to the yield strength of the round bar For example F1554 grade 36 has a minimum yield strength of 36 000 lbs per square inch grade 55 has 55 000 lbs per Overview ASTM F1554 grade 105 anchor bolts are manufactured from medium carbon alloy steel that has been quenched and tempered heat treated to develop the desired mechanical values This is the highest strength version of the F1554 specification with a minimum yield strength of 105 ksi covering anchor bolts in diameters ranging from 1 2″ through 3″ 2019 7 25 nbsp 0183 32 ASTM F1554 includes a Grade 55 which can be ordered to Supplementary Requirement S1 which ensures weldability There is also a Grade 105 for high strength applications which is a heat treated material hence it cannot be ordered to Supplementary Requirement S1 to ensure weldability It should be noted that threaded rods are typically used F1554 Grades F1554 Grade 36 Low carbon 36 ksi yield steel anchor bolts These roughly correspond to the previous ASTM A307 or to ASTM A36 F1554 Grade 55 Medium strength low alloy 55 ksi yield steel anchor bolts F1554 Grade 105 105 Alloy heat treated high strength 105 ksi yield steel anchor bolts

F1554 anchor bolts can take the form of either headed bolts straight rods or bent anchor bolts The three grades 36 55 and 105 designate the minimum yield strength ksi of the anchor bolt The bolts can be either cut or roll threaded and a weldable grade 55 can be substituted for grade 36 at the supplier s option 2012 12 4 nbsp 0183 32 Welding F1554 Grade 105 cannot be welded F1554 Grade 105 develops its strength characteristics when it is quenched and tempered heat treated Welding or applying heat to F1554 Grade 105 material will change the mechanical properties of the anchor bolt According to the Ninth edition of the American Institute of Steel Construction AISC 2020 11 20 nbsp 0183 32 These ASTM F1554 Anchor Bolts are available in various designs and different alloy grades such as carbon steel carbon boron alloy steel or even high strength low alloy steel However according to the ASTM F1554 2005 12 28 nbsp 0183 32 Can F1554 GR 105 anchor bolts be field welded to the nuts and to A992 base plates as a fix for Welding to the threaded portion of a rod is permissible If larger uplift forces Someone sent me a copy of a qualified welding procedure for a butt welded 3 quot diameter high strength heat treated rod using a double 2014 8 22 nbsp 0183 32 Either way a mill certification that indicates Grade 55 and S 1 indicates the steel from that heat is weldable and compliant with ASTM F1554 Note A 105 round bar is not recommended to be welded It draws its strength
