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.

Reasons such as off-topic, duplicates, flames, illegal, vulgar, or students posting their homework. Promoting, selling, recruiting, coursework and thesis posting is forbidden.

Ok, so taking the engineering approach, I calculated the CE: Hahah Thanks for listening. Can you quantify it, maybe with carbon content of either? Yes, sadly I am working Today: With ,you need to add Ni and Mo,some add copper too. Posting Guidelines Promoting, selling, recruiting, coursework and thesis posting is forbidden. However, to successfully apply the CE equation you need to know the chemical composition of the steels you are joining.

Download Now Defense manufacturing is all about project manufacturing and project accounting. The switch to the higher strength casting only provides more margin for strength, nothing else. The issue of cracking susceptibility ast, not factor in given the statement above. Defense manufacturing is all about project manufacturing and project accounting.

MechEng; Given your statement above, Quote: Download Now White Paper: I got the values, as I make those grades 90-660 castings. How much less weldable is compared to ? Digital Transformation may be defined in a number of different ways by analysts or enterprise software vendors. Are you an Engineering professional?

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

It’s easy to join and it’s free. 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 A Grade is weldable with suitable precautions for preheat and possible post weld heat treatment. Please refer to the specs.

I intentionally gave you the values as the standard does not specify chemistry or heat treatment,it only specifies the mechanical properties.

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.

I just want to make sure awtm switch to the higher grade material will be worth the change. The foundry and casting user together decide the chemistry. 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.
