Duplex Steel S31803 Socket Set Screws is a stainless steel whose design allows uniting better – quality of resistance to pitting, soaring potency, stress corrosion, cracking and crevice corrosion. Meanwhile, these Duplex Steel S32205 Anchore Screws are also being offered in different sizes and shapes to our customers. As further discussed elsewhere, exposure of a Duplex Steel S31803 Blind Rivet Screws to temperatures in the range of 1100 Degree F – 1825 Degree F can cause precipitation of intermetallic phases with substantial loss of corrosion resistance.
These precipitates in Duplex Steel S32205 Concrete Screws are better detected by tests for critical pitting temperature or critical crevice temperature in strong chloride environments, and not by the ASTM tests commonly used for sensitization to inter – granular corrosion. We also offer these Duplex Steel S31803 Threaded Screws in customized sizes and shapes for our esteemed clients.
