I am looking for Charpy V Notch curves for ASTM A148 grades:
90-60
105-85
115-95
130-115
Anybody have this information available?

Be careful, some of the data is for unnotched specimens.
RE: ASTM A148 CVN info
Grade 90/60 for example can be made using a number of different materials. We have made it with 1045, 1520, 1524, 8620, 8625, 8630 and even a 4140 depending on the customers requirements. If no impact are required we would use 1524 in the normalize state. This will not provide great impact properties. If impacts are required we would use the 8620 or 8625 and quench and temper the parts.
Even on the high end with 130-115 there are a number of common cast materials you can use. 4130, 8633, or 4320 would all be good choices but will yield different impact properties.
What are you trying to do with the information?

Select a material composition to achieve the required minimum strength level for the casting and conduct CVN testing on coupons per Supplementary requirement S.9

Thanks for the additional input.
