a913 Gr. 65 Steel

a913 Gr. 65 Steel

(OP)
Looking to find some more information on a913 steel and what exactly is needed for its use in structural steel design. What I've come across so far is a lot of positive talk about cost cutting and it's ability to be welded without a preheating process. But being a quenched and tempered steel will there be a post weld heat treatment needed..will there be any brittle problems that could arise? I also am seeing the wire that would need to be used and the procedures won't be prequalified, am I correct with this? If anyone could direct me to a good article or site that points out both the pros and cons of this type of steel it would be greatly appreciated.  

RE: a913 Gr. 65 Steel

You should take a look at the A913 specification.  Weldibility issues are directly addressed by referring to ASTM A6 Section X3.  A913 also has limits on carbon equivalency.  This value should be calculated in determining PWHT.  You should not need preheat or PWHT if this value is at or below 0.35 using the formula presented.

Because of the lower carbon content this steel has improved weldability. Howqever, as with any high strength low alloy steel heat input from welding  must be controlled. Your interpass temperature should be less than 300 deg F, otherwise the bulk properties will be affected - reduced strength.
