In professional kitchens their broilers are 700-1000 degrees. Your oven doesnt get that hot but rule of thumb in broiling is the hotter the better. If you want restaurant quality results. When I make a steak in the oven I set the oven on broil and the highest setting and let it get good and hot. I put the broiling pan on the top rack and when I am cooking I leave the oven door slightly cracked. Now time has to to do with how thick the steak is and what degree of doneness you prefer. I like medium rare so for a 1 inch steak about 5 minutes on each side usually does the trick in my oven. Your cooking time will vary.
I usually turn my oven to broil and use the broiler...but I like my steak fairly rare. Most meat cooks at about 350, for 30 minutes, depending on how rare you like your steak. If you want a good sizzle on the outside, turn it on the broiler to brown for a few minutes just before the steak reaches how well done you like it to be.
