60% or D-
Yes, it typically is. Although most jobs will spec Grade 40, most fabricators stock grade 60 and use it for all applications as it is easier and more cost effective to have one inventory and grade as opposed to two. The Grade 60 is stronger than grade 40 and thus can replace 40 without any problems. Most benders a made to handle the stronger materials anyway, so there should be no problems supplementing 60 for 40.
40% of the grade of 96 and 60% of the grade of 50 gives (.4x96+.6x50) = grade of 68
60 percent of 40 = 2460% of 40= 60% * 40= 0.60 * 40= 24
60% is not normally a passing grade in college.
Grade 60 has a tensile stress of 60000 psi while Grade 40 has 40000. Grade 60 steel rusts faster than grade 40. grade 60 bar can be identified by the word 60 which should have printed on that while on grade 40 no no will be printed or written and we can identify this by counting the lines on steel as well. If there are 3 lines longitudinally on the bar its is of 60 grade and if 2 lines longitudinally it will be identified as 40 grade.

Grade 40 steel is preferred over grade 60, especially in areas which are situated near or on the main fault line. Thus, these areas are more prone to earthquakes and grade 40 steel is expected to take more force of 40000 psi before it breaks down.
Missing information - you need the worth (weight) for every grade, not just for some of them. The way you calculate this so-called "weighted average" is to multiply each grade by its weight, and add everything up. Then you divide by the total "weight". Example: exam 1: grade is 80; weight is 40. exam 2: grade is 70; weight is 60. 80 x 40 + 70 x 60 = 3200 + 4200 = 7400. Divide this by the total weight (40 + 60 = 100), and you get a weighted average of 74.

sae document j300 defines the highest single grade as 60. this is in reference to viscosity and not the quality of the oil
60 -20 = 40
60 percent would normally be a grade of D.
