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.

ASTM is a high strength steel casting of grace grade. However,certain precautions need to be taken before welding.

Please refer to the grae. Thanks for the responses, I have a few more questions. Yes, sadly I am working Today: I got the values, as I make those grades of castings.

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 – Metal and Metallurgy engineering – Eng-Tips

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.

The carbon equivalent CE equation is used to evaluate “weldability” of steel cast or wroughtwhere besides carbon content, other alloying elements as arunmrao mentioned astk considered.

However, to successfully apply the Xstm equation you need to know the chemical composition of the steels you are joining. How much less weldable is compared to ? Can you quantify it, maybe with carbon content of either? With ,you need to add Ni and Mo,some add copper too. The heat treatment cycle varies in each of 9-060 2 cases. I noticed the Manganese is less for A27, does that mean it welds better or easier?

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. I just want to make sure the switch to the higher grade material will be worth the change.

MechEng; Given your statement above, Quote: Ok, so taking 9-060 engineering approach, I calculated the CE: 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?

Weldability of ASTM A Yes, awtm as the carbon content is lowered because of lower strength requirements the weldability of the steel increases, where preheat and other measures grae prevent cracking are less likely.

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.
