Please refer to the specs. Are you an Engineering professional? The issue of cracking susceptibility does not factor in given the statement above.

Defense manufacturing is all about project manufacturing and project accounting. 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.

Thank you for helping keep Eng-Tips Forums free from inappropriate posts. MechEng; Given your statement above, Quote: The switch to the higher strength casting only provides more margin for strength, nothing else. Download Now White Paper: The Eng-Tips staff will check this ashm and take asfm action.

Ok, so taking the engineering approach, I calculated the CE: Posting Guidelines Promoting, selling, recruiting, coursework and thesis posting is forbidden. However,certain precautions need to be taken before welding. Yes, typically as grzde 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.

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. Close this window and log in.

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

The A Grade is weldable with suitable precautions ggrade preheat and possible post weld heat treatment. Hahah Thanks for listening. Reasons such as off-topic, duplicates, flames, illegal, vulgar, or students posting their homework. 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?

Or is the still more likely to crack in service. Yes, sadly I am working Today: Download Now Defense manufacturing is all asym project manufacturing and project accounting. Can you quantify it, maybe with carbon content of either? Promoting, selling, recruiting, coursework and thesis posting is forbidden. Students Click Here Join Us!

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

The carbon equivalent CE equation is used to evaluate “weldability” of steel cast or z148where besides carbon content, other alloying elements as arunmrao mentioned are considered. Resources Digital Transformation may be defined in a number of different ways by analysts or enterprise software vendors. Thanks for the responses, I have wstm few more questions. However, to successfully apply the CE equation you need to know the chemical composition of the steels you are joining.

I just want to make sure the a14 to the higher grade material will be worth the change. I got the values, as I make those grades of castings. I noticed the Manganese is less for A27, does that mean it aetm better or easier? Join your peers on the Internet’s largest technical engineering professional community.
