See the chemical composition and physical properties of ASTM A Grade 60 [], find alternative materials, and connect with suppliers. ASTM. Chemical Requirements. Tensile Requirements. STEEL GRADE. Carbon. Manganese. Silicon ASTM A, Grade N/A. N/A. N/A. Is ASTM A Gr a weldable grade and welder friendly? What should be the preheat and interpass temp. Can i get some technical.

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

The foundry and casting user together decide the chemistry. It’s easy to join and it’s free. I intentionally gave a184 the values as the standard does not specify chemistry or heat treatment,it only specifies the mechanical properties. Yes, sadly I am working Today: Ok, so taking the engineering approach, I calculated the CE: However,certain precautions need to be taken before welding. Close this window and log in.

Are you an Engineering professional? The heat treatment cycle varies in each of the 2 cases. MechEng; Given your statement above, Quote: Thanks for the responses, I have a few more questions. Red Flag This Post Please let us know here why this post is inappropriate.

Thank you for helping keep Eng-Tips Forums grde from inappropriate posts. Can you quantify it, maybe with carbon content of either? I just want to make sure the switch to the higher grade material will be worth the change. Digital Transformation may be defined in a number of different ways by analysts or enterprise software vendors.

ASTM is a high strength steel casting of weldable grade. By joining you are opting in to receive e-mail. The Eng-Tips staff grde check this out and take appropriate action. 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.

Join your peers on the Internet’s largest technical engineering professional community. How much less weldable is compared to ? The switch to the higher strength casting only provides more margin for strength, nothing else.

Weldability of ASTM A Grads, 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. However, to successfully apply the CE equation you need to know the chemical composition of the steels you are joining.

Hahah Thanks for listening. Yes, typically as the carbon content is lowered graxe of lower strength requirements the weldability of the steel increases, where preheat and other measures to prevent cracking are less likely.
