ASTM A148 GRADE 90-60 PDF

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 carbon equivalent CE equation is used to evaluate “weldability” of steel cast or wrought x148, where besides carbon content, other alloying elements as arunmrao mentioned are considered. Close this window and log in. How much less weldable is compared to ?

Yes, sadly I am working Today: 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. Reasons such as off-topic, duplicates, flames, illegal, vulgar, or students posting their homework. Ok, so taking the engineering approach, I calculated the CE: Promoting, selling, recruiting, coursework and thesis posting is forbidden.

Or is the still more likely to gradw in service. The tumbleweed blows across the quiet desert landscape, with nothing in its path grwde faces a quiet isolation but hopefuly it will find a Material Science Expert to once again help its cause?

The issue of cracking susceptibility does not factor in given the statement above. Can you quantify it, maybe with carbon content of either? MechEng; Given your statement above, Quote: The heat treatment cycle varies in each of the 2 cases. Please refer to the specs. By joining you are opting in to receive e-mail.

ASTM is a high strength steel casting of weldable grade.

I noticed the Manganese grzde less for A27, does that mean it welds better or easier? However, to successfully apply the CE equation you need to know the chemical composition of the steels you are joining. Red Flag This Post Please let us know here why this post is inappropriate.

I intentionally gave you the values as the standard does not specify chemistry or heat treatment,it only specifies the mechanical properties. Posting Guidelines Promoting, selling, recruiting, coursework and thesis posting is forbidden. Hahah Thanks for listening. I just want to make sure the switch to the higher grade material will be worth the change.

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. Students Click Here Join Us! The Eng-Tips staff will check this out and take appropriate action.

The switch to the higher a418 casting only provides more margin for strength, nothing else. However,certain precautions need to be taken before welding.

Thanks for the responses, I have a few more questions. The A Grade is weldable with suitable precautions for preheat and possible post weld 90-06 treatment.
