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.

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. Posting Guidelines Promoting, selling, recruiting, coursework and thesis posting is forbidden. However,certain precautions need to be taken before welding. However, to successfully apply the CE equation you need to know the chemical composition of the steels you are joining.

Thanks for the responses, I have a few more questions. 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?

ASTM A148 Grade 90-60 [620-415]

I just want to make sure the switch to the higher grade material will be worth the change. Can you quantify it, maybe with carbon content of either? I got the values, as I make those grades of castings.

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? Ok, so taking the engineering approach, I calculated the CE: Close this window and log in.

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.
