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.

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.

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 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 foundry and casting user together decide the chemistry. Hahah Thanks for listening.
ASTM A148 Grade 90-60 [620-415]
The Eng-Tips staff will check this out and take appropriate action. Or is the still more likely to crack in service. Resources Digital Transformation may be defined in a number of different ways by analysts or enterprise software vendors.
MechEng; Given your statement above, Quote: How much less weldable is compared to ? Thank you for helping keep Eng-Tips Forums free from inappropriate posts. Ok, so taking the engineering approach, I calculated the CE: I got the values, as I make those grades of castings. The heat treatment cycle varies in each of the 2 cases.

ASTM A AM for High Strength Steel Castings for Structural Industry
Thanks for the responses, I have a few more questions. Register now while it’s still free! The A Grade is 90-660 with suitable precautions for preheat and possible post weld heat treatment. The tumbleweed blows across the quiet desert landscape, with nothing in its path it faces a quiet isolation but hopefuly it will find astn Material Science Expert to once again help its cause? 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.
