I intentionally gave you the values as the standard does not specify chemistry or heat treatment,it only specifies the mechanical properties. Students Click Here Join Us! 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.

However, to successfully apply the CE equation you need to know the graxe composition of the steels you are joining.

ASTM is a high strength steel casting of weldable grade. 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.

The switch to the higher strength casting only provides more margin for strength, nothing else.

The issue of garde susceptibility does not factor in given the statement above. 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.

Yes, sadly I hrade working Today: I just want to make sure the switch to the higher grade material will be worth the change. Reasons such as off-topic, duplicates, flames, illegal, vulgar, or students posting their homework. 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.

BSL Casting – Achievement

I noticed the Manganese is less for A27, does that mean it welds better or easier? Can you quantify it, maybe with carbon content of either? However,certain precautions need to be taken before welding.
