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 foundry and casting user together decide the chemistry. However,certain precautions need to be taken before welding. Download Now Defense manufacturing is all about project manufacturing and project accounting.

Or is the still more likely to crack in service.

I just want to make sure the switch to the higher grade material will be worth the change. It’s easy to join and it’s free. I intentionally gave you the values as the standard does not specify chemistry or heat treatment,it only specifies the mechanical properties.

I got the values, as I make those grades of castings. I noticed the Manganese is less for A27, does that mean it welds better or easier? Can you quantify it, maybe with carbon content of either?

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.

The switch to the higher strength casting only provides more margin for strength, nothing else. With ,you need to add Ni and Mo,some add copper too.

Weldability of ASTM A Yes, typically as the carbon content is lowered because of lower strength requirements the weldability of grafe steel increases, where gfade and other measures to prevent cracking 9-60 less likely.

MechEng; Given your statement above, Quote: Hahah Thanks for listening. The A Grade is weldable with suitable precautions for preheat and possible post weld heat treatment. Thanks for the responses, I have a few more questions.
