They contain a specified minimum content of cobalt, columbium, boron, aluminium, molybdenum, nickel, titanium, vanadium and zirconium.
For example, if the chromium content is more than 4-percent, the metal starts to become stainless instead of alloy. B7 and B7M bolts are heat treated alloy steel studs that are commonly used for high-pressure and high-heat operations. They come in sizes ranging from one-quarter inch to 4-inches in diameter. You need to determine the actual service stress in each stud and compare that with the allowable stress value at deg F. Considering how close the allowables are for these materials, off-hand I would say that you should see no real difference in using B7 and B7M.
However, you need to substantiate this with an engineering analysis. You know the pressure, now calculate the load on each stud. Knowing the cross sectional area of each stud you should be able to calculate the tensile stress. B7M bolts can be used without any analysis on standard flanges. These are intermediate strength per B So, you can do one of two things, either install the intermediate strength studs and hope for the best in terms of a leak tight joint or perform an engineering analysis to verify that a leak tight joint would prevail by determining the correct preload.
The former is correct since the latter has been verified a million times over. If you were experienced in flange design you would already know this. Met the same question last week. After some research then found that B7M is mainly used in the potentially corrosive service.
The carbon in B7M is a little lower than that in B7, so the stress corrosion crack could be avoided by using B7M.
It's a modified grade. Regards, FKE. B7M bolts are specifically for applications where bolting could be exposed to the H2S-containing environment. HRC 22 is the maximum allowable hardness.
