It depends on how the steel is heat treated, so there isn't a single answer.

EN45 is a medium carbon steel typically used for spring applications due to its good hardness and tensile strength. Its equivalent grades in other standards include ASTM A228 (for music wire) and SAE 1095. In terms of European standards, it may also correspond to grades such as 1.0503 or C60, depending on the specific requirements and applications. Always consult a detailed material specification chart for precise equivalencies based on desired properties.
SAE stands for Society of Automotive Engineers. Sae ratings pertain to the oils Viscosity. Viscosity is the flowability (resistance to flow) at a particular temperature.
10.9 on a metric bolt indicates the hardness (or load, tensile strength, and hardness) of the bolt. This is almost as high as they get and is about the equivalent to a grade 8 SAE or USS bolt. 8.8 is also a common metric hardness.
It will depend on the Alloy. You need the alloy steel AISI - SAE material designation; such as 4140 or 8620. Mechanical engineering handbooks will have the mechanical properties listed in an appendix; such as UTS, YS, Modulus (E), etc. In addition, steel distributor's will have books (free) that have the mechanical properties listed. I did attempt to add a website as an example of where you could go on-line as well. I am not sure where or how the link will appear.

Bolts are typically classified into several grades based on their strength and material properties. Common grading systems include the American Society for Testing and Materials (ASTM) grades, such as ASTM A307, A325, and A490, as well as the SAE grades, like Grade 2, Grade 5, and Grade 8. Additionally, metric bolts are graded according to ISO standards, such as 8.8, 10.9, and 12.9. Each grade indicates the bolt's tensile strength and suitability for different applications.

SAE 40 has a higher viscosity.
SAE 40 has a higher viscosity.
SAE 10w30 is better for lower temp and SAE 20w40 is the opposite better hotter temps.Thanks
SAE sets standard sizes and grades for bolts.Size and Grade are different:Size is set By the SAE (society of Automotive engineer's) and is stated as thickness followed by thread pitch followed by length 1/4 x 24 (threads per inch) x 1 1/14 (inches long) Grade Is a statement of strength and hardness. Most auto hardware tends to be grade 5 and some high strength stuff is grade 8 or grade 12
If there are lines coming inward from the outside on the head then this is an SAE bolt, not metric. If there are three of these lines than it is a grade five bolt.
