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.

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

How much less weldable is compared to ? The heat treatment cycle varies in each of the 2 cases. Red Flag This Post Please let us know here why this post is inappropriate. 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. Please refer to the specs.

I just want to make sure the switch to the higher grade material will be worth the change. However, to successfully apply the CE equation you need to know the chemical composition of the steels you are joining.

Defense manufacturing is all about project manufacturing and project accounting. 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 rgade to prevent cracking are less likely. The switch to the higher strength casting only provides more margin for strength, nothing else.

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. Or is the still more likely to crack in service. Can you quantify it, maybe with carbon content of either? Students Click Here Join Us!

Ok, so xstm the engineering approach, I calculated the CE: I noticed the Manganese is less for Axtm, does that mean it welds better or easier?
