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 Eng-Tips staff will check this out and take appropriate action. Defense manufacturing is all about project manufacturing and project accounting.
Hahah Thanks for listening. The switch to the higher strength casting only provides more margin for strength, nothing else. The issue of cracking 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.

However,certain precautions need to be taken before welding. 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?
Yes, sadly I am working Today: Click Here to join Eng-Tips and 9-060 with other members! 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. I grsde gave you the values as the standard does not specify chemistry or heat treatment,it only specifies the mechanical properties. Resources Digital Transformation may be defined in a number of different ways by analysts or enterprise software vendors.
Reasons such as off-topic, duplicates, flames, illegal, vulgar, or students posting their homework. I just want to make sure the switch to the higher grade material will be worth the change.
The heat treatment cycle varies in each of the 2 cases. Students Click Here Join Us! Can you quantify it, maybe with carbon content of either? With ,you need to add Ni and Mo,some add copper too. Close this window and log in.

However, to successfully apply the CE equation you need to know the chemical composition of the steels you are joining. How much less weldable is compared to ? It’s easy to join and it’s free. Ok, so grrade the engineering approach, I calculated the CE: Download Now White Paper: Posting Guidelines Promoting, selling, recruiting, coursework and thesis posting is forbidden.

Thanks for the responses, I have a few more questions. Z148 A Grade is weldable with suitable precautions for preheat and possible post weld heat treatment. Are you an Engineering professional? I got the values, as I make those grades of castings. Thank you for helping keep Eng-Tips Forums free from inappropriate posts.
MechEng; Given your statement above, Quote: 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.
Register now while it’s still free! I noticed the Manganese is less for A27, does that mean it welds better or easier? The foundry and casting user together decide the chemistry.
Or is the still more likely to crack in service.
