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.

Weldability of ASTM A 990-60 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: I just want to make sure the switch to the higher grade material will be worth the change.

Grqde you quantify it, maybe with carbon content of either? I noticed the Manganese is less for A27, does that mean it welds better or easier? Ok, so taking the engineering approach, I calculated the CE: Please refer to the specs. ASTM is a high strength steel casting of weldable grade.

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

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 gfade prevent cracking are less likely. With ,you need to add Ni and Mo,some add copper too. Close this window and log in. Click Here to join Eng-Tips and talk 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.

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. I intentionally gave you the values as the standard does not specify chemistry or heat treatment,it only specifies the mechanical properties. The heat treatment cycle varies in each of the 2 cases.
