Stainless Steel Threaded Rod Strength

Threaded rod is a continuous length of round bar that has a thread on its external diameter so a nut can be screwed on from either end.

Stainless steel threaded rod strength.

The type of stainless steel desired for the project will be specified as a grade within the a193 and a320 specifications or as a alloy group and condition within the f593 specification. 304 and 316 stainless steels respectively. Grades 8 and b7. This chromium molybdenum steel has similar strength to sae grade 5 fasteners however it is specifically used in high temperature and pressure applications.

Metric threaded rods are marked on the rod tips with a color code. Threaded rods proof load capacities in metric units. Stainless steel threaded rod is also available in a2 and a4 stainless steel which are the same as u s. These hardened 316 stainless steel threaded rods are 40 stronger than standard grade b8m threaded rods.

Class 8 8 and10 9 are classified as alloy steel quenched and tempered and are similar to u s. Threaded rd plain inc galvanied stainless steel doc. Depending on the ratio of metals in the alloy the definitive strength of most stainless steel grades will range from about 70 to 220 ksi. Threaded rod tds version date.

They have higher corrosion resistance than steel threaded rods and studs and are ideal for use in wet environments where male threads are needed for the full fastener length. 1 the maximum loads in the table above are based on allowable tensile stress of 12 kpsi reduced by 25 to 9 kpsi allowable stress. Bbv11 page 01 256. 1 kg 9 81 n.

Note that hangers supporting steam water air or gas piping systems should be able to carry the weight of piping insulation valves and other equipment. This grade is for fittings flanges valves and pressure vessels. Often also referred to as all thread running thread threaded bar or studding stainless steel threaded rod is usually class 50 tensile strength by default but is available ex stock in class 80 which is our bumax threaded rod. Supply chain availability available.

3 8 16 x 6 ft astm f593 gr 18 8 stainless steel threaded rod. They meet the pressure and temperature requirements of astm a193 and are often used to secure pressure tanks valves and flanges. Stainless steel threaded rod proves when tested to be stronger than most grade 2 steels but weaker than grade 5 and grade 8 stainless steel raw materials that have been hardened. It is also used as threaded rod in concrete and epoxy.
