disc joint sizing

Good evening, I'd need help with a mechanical technology project. In practice I have to design a hard joint with disks, precisely one flange, knowing the power (about 155 kw) that must deliver the motor to which I have to connect it. I assumed an electric motor with two pairs of poles, so that it turns to 1500rpm, do you think it is right as an idea? Second, I had doubts about the material to make the joint by supposing using a c40 steel for the tree. I was undecided between a c45 steel and a stainless steel as they are those I found on the internet. Can you give me more information about this?
I attach the photo of the joint to be realized

subject already dealt with. if the search for the forum does not result or seems farraginous do a google search with keywords and site indication, for example site disc joint:www.cad3d.it

ok perfect thank you so much, now I take a look and see if I find an answer
 
after you read all the posts, ask us the question. I think a lot of information can be found in the posts we've already answered. Actually also on the net using google are found many exercises solved.

stainless steel is used if they have to resist corrosion. for normal mechanics c45 is used for normal applications, s275jr for poor applications and 42crmo4 or similar related for strongly stressed abers.
 
one of the various possible solutions of the joint can be this attached.Screenshot_20210422_001842.webpScreenshot_20210422_001902.webpdefinitely would be nice in the calculation you do, use the norm uni en 1993-1-8 instead of the ex cnr uni 10011 for the calculation of bolting.
other thing is the choice of the application factor that can be different.
different materials, more resistant.
class bolts and number screws.
friction coefficients more and less grip.

should be evaluated, hypothesized and contextualized.
