Creep rupture strength, R km , 100 000 MPA (EN 10095) Alloy 253 MA EN 1.4835 Versus AISI 310, at 900°c 253ma is almost 3 times stronger than AISI 310


I can only list the issues we face and as I have said sometimes we have to make compromise on the alloy used, the size and shape of anchors. In this training day you are not going to learn everything and be an expert but should you need help on the design you can always contact us at contact@anchorsforrefractory.com.


Once you have made your design and have purchased your anchors it


Technical Paper


is very important that they are packed and are identifiable easily in most cases it


will be one of


your site people who is going to be using the anchors so they need to be able to identify them easily from the packing, you can’t see if material is 304 SS or 310 SS it looks the same, but if lower temperature material is used at higher temperatures there will be failures, so packing /identification is worth paying for to provide identification and traceability of the alloy.
