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.

Yes, typically as the carbon content is lowered because of lower strength requirements the weldability of the steel increases, where preheat and grqde measures to prevent cracking are less likely. With ,you need to add Ni and Mo,some add copper too. Digital Transformation may be defined in a number of different ways by analysts or enterprise software vendors.
I got the values, as I make those grades of castings. However,certain precautions need to be taken before welding. Yes, sadly I am working 90-0 The A Grade is weldable 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 a Material Science Expert to once again help its cause? Or is the still more likely to crack in service.

Thanks for the responses, I have a few more questions. I just want to make sure the switch to the higher grade material will be worth the change. Red Flag This Post Please let us know here why this post is inappropriate.

Ok, so taking the engineering approach, I calculated the CE: Are you an Engineering professional? The issue of cracking susceptibility does not factor in given the statement above. However, to successfully apply the CE equation you need to know the chemical composition of the steels you are joining.
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 heat treatment cycle varies in each of the 2 cases. The Eng-Tips staff will check this out and take appropriate action.

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. Thank you for helping keep Eng-Tips Forums free from inappropriate posts.
I intentionally gave you the values as the standard does not specify chemistry or heat treatment,it only specifies the mechanical properties. The foundry and casting user together decide the chemistry. Click Here to join Gfade and talk with other members! By joining you are opting in to receive e-mail.
