Weldability of ASTM A148 - Metal and Metallurgy weldability of astm a148 metal and metallurgy Jan 06, 2011· Assuming all precautions for welding are taken (electrode, heat treat), and the weld is performed properly is the ASTM A148 - 90-60 more robust when compared to ASTM A27 - 70-36? Or is the 90-60 still more likely to crack in service.astm a148 - Carbon steel castings | Stainless steel castingsWeldability of ASTM A148 - Metal and Metallurgy weldability of astm a148 metal and metallurgy Jan 06, 2011· Assuming all precautions for welding are taken (electrode, heat treat), and the weld is performed properly is the ASTM A148 - 90-60 more robust when compared to ASTM A27 - 70-36? Or is the 90-60 still more likely to crack in service.What is the weldability of steel?As with carbon steels, the weldability of steels with more than 0.2% carbon is considered to be poor. This is due to their hardness and risk of cracking when welded. Tool Steels, which contain 0.32.5% carbon, are therefore difficult to weld and many steel suppliers will actually recommend against it.See all results for this question
