However, we do not have any engineers on staff, so we cannot speak to all the possible risks, but what we can say is that 2HM nuts are quite specialized, and I would assume there is a good reason that they were originally specified. Cherry — Apologies, but we are not familiar with MS material and a quick Google search does not bring up any results. Sorry we could not help. At least Can We say the stud bolts are stronger than machine bolts?

Richard — 2H and 2HM nuts are not the same strength eaparragos are lower strength, but rated for higher temperatureso I would recommend against substituting one for the other. There are some significant differences in both the mechanical properties and the testing requirements of AB7M and AB7.

You can find summaries for both ASTM standards on our website. You may need to contact an engineer or metallurgist.

ASTM A is a low carbon steel, low strength, general purpose bolt standard. This is a different grade of material than A Espargagos B7. Dear sir, May you help me about material specifications… I have a problem about material MS Any substitution should be run by an engineer.

The design temperature of the tank is 85 deg C only. What is the difference between B7M and B7M comply to nace mr B16 or A Gr. However, I find some contradicting answers when searching around, can it be both depending on the heat treatment and consequent microstructure?

We have summaries for both ASTM standards on our website. What is the heat treatment process of astm a grade b7m??? Why is this line esaprragos mentioned in numerous doccuments? That said, ASTM F washers are an off the shelf, very common washer that may provide the same benefit at a much lower cost. Vijay- Of those, A B7 is the closest to grade 8.

Same as baking a cake — if it is large, the center never gets espwrragos done. Martin- For all intents and purposes, they are the same.


I have a query. Ari- There are some similarities in tensile and yield, but they are not identical.

Waqas- You are correct, no further processing is exparragos after final heat treatment. The most notable difference from a manufacturing perspective is that when providing AB7M bolts, every individual bolt or stud in the lot must be hardness tested.

You will need to consult the project engineer and get their approval for the substitution. I understand we could not tighten the internals bolts B7M in our case and it should withstand in extreme process condtion i. Even a simple cutting process will require an additional heat treat process.

John — A section 9. We are not familiar with a bolt specifically called a mushroom head. Why Grade B7M shall have a line under the grade symbol? It is up to the designer or engineer if they are required or not.
