Are you an Engineering professional? ASTM is a high strength steel casting of weldable grade.
Weldability of ASTM A – Metal and Metallurgy engineering – Eng-Tips
Weldability of ASTM A The tumbleweed blows across the quiet desert landscape, with nothing in its path it faces a quiet isolation but hopefuly it will find a Material Science Expert to once again help its cause? The A Grade is weldable with suitable precautions for preheat and possible post weld heat treatment.
Students Asfm Here Join Us! Ok, so taking the engineering approach, I calculated the CE: Download Now White Paper: Because of their lower strength, fewer precautions are required for welding, in comparison to higher strength grades, and they are less sensitive to cracking during or after welding.

Thanks for the responses, I satm a few more questions. Or is the still more likely to crack in service. However,certain precautions need to be taken before welding. The heat treatment cycle varies in each of the 2 cases. I got the values, as I make those grades of castings. Promoting, selling, recruiting, coursework and thesis posting is forbidden.

Weldability of ASTM A Yes, typically as the carbon content is lowered because of lower strength requirements the weldability of the steel increases, where preheat and other measures to prevent cracking are less likely.

Hahah Thanks for listening. Can you quantify it, maybe with carbon content of either? However, to successfully apply the CE equation you need to know the chemical composition of the steels you are joining. Yes, sadly I am working Today: The tumbleweed blows across the quiet desert landscape, with nothing in its path it faces a quiet isolation but hopefuly it will find a Material Science Expert to once again help its cause?
Thank you for helping keep Eng-Tips Forums free from inappropriate posts. I noticed the Manganese is less for A27, does that mean it welds better or easier? The switch to the higher strength casting only provides more margin for strength, nothing else.
It’s easy to join and it’s free. I just want to make sure the switch to the higher grade material will be worth the change. Register now while it’s still free!

Yes, typically as the carbon content is lowered because of lower strength requirements the weldability of the steel increases, where preheat and other measures to prevent cracking are less likely.
The carbon equivalent CE equation is used to evaluate “weldability” of steel cast or wroughtwhere besides carbon content, other alloying elements as arunmrao mentioned are considered.
MechEng; Given your statement above, Brade How much less weldable is compared to ? I intentionally gave you the values as the standard does not specify chemistry or heat treatment,it only specifies the mechanical properties.
