We have an project and for the bolt requirement stated in project specs is "Bolts for ladders shall be stainless steel grade A4-80 with tensile strength fu = 800 MPa", We are going to use HST-R M16x145 Bolt, if it can comply with the specs?
Hi Chris,
Thank you very much for your question. The ultimate tensile strength of 800N/mm2 for stainless steel is a pretty rare requirement.
As you can see from the below table, HST ultimate strength for stainless steel is less than 800N/mm2.
If you want M-16 size anchor itself, you have to go for HDA Anchors.
If you can go for lower diameter anchors, you can go for HUS-HR Anchors.
As you can see below, the full diameter of HUS anchors will be 16mm for M14.
Please feel free to comeback if you need anything more.

Hello Chris Lee,
It's an interesting topic, thank you for asking.
As Hani stated, typically, it is a rare requirement to have that high tensile capacity for stainless steel,
Stainless steel is different from regular steel with the inclusion of elements such as: chromium, nickel, molybdenum, etc. This mixture of different elements, typically, reduces the tensile strength of stainless steel materials when compared to let's say 8.8 grade steel material.
My suggestion would be to make a design with the anchor of your choice and see if the steel resistance of the product is enough or not for your specific design case.
