Can you quantify it, maybe with carbon content of either? Join your peers on the Internet’s largest technical engineering professional community. The foundry and casting user together decide the chemistry. Thank you for helping keep Eng-Tips Forums free from inappropriate posts. MechEng; Given your statement above, Quote: The issue of cracking susceptibility does not factor in given the statement above.

Are you an Engineering professional? However,certain precautions need to be taken before welding. Promoting, selling, recruiting, coursework and thesis posting is forbidden. Download Now White Paper: 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 heat treatment cycle varies in each of the 2 cases. Register now while it’s still free!

The switch to the higher strength casting only provides more margin for strength, nothing else. Yes, sadly I am working Today: Download Now Defense manufacturing is all about project manufacturing and project accounting.

Digital Transformation may be defined in a number of different ways by analysts or enterprise software vendors. 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. Ok, so taking the engineering approach, I calculated the CE: Red Flag This Post Please let us know here why this post is inappropriate.

ASTM A148/A148M Grade 620-415(90-60)

I intentionally gave you the values as the standard does not specify chemistry or heat treatment,it only specifies the mechanical properties. However, to successfully apply the CE equation you need to know the chemical composition of the steels you are joining.

The carbon equivalent CE equation is used to evaluate asym of steel cast or wroughtwhere besides carbon content, other alloying elements as arunmrao mentioned are considered. With ,you need to add Ni and Mo,some add copper too.

Please refer to the specs. Students Click Here Join Us! 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 Eng-Tips staff will check this out and take appropriate action. The A Grade is weldable with suitable precautions for preheat and possible post weld heat treatment. I just want to make sure the switch to the higher grade material will be worth the change.

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.

I noticed the Manganese is less for A27, does that mean it welds better or easier?
