Heat-treated martensitic stainless steel pipes with improved mechanical qualities are known as stainless steel 416HT pipes. Usually, the composition has a low carbon content, 12–14% chromium, and 0.15% sulphur for better machinability. While preserving good dimensional stability, the heat treatment (HT) process raises hardness (up to 30–35 HRC), yield strength (~450 MPa), and tensile strength (up to 700 MPa). These pipes are perfect for parts that need a high degree of strength and precision because they have good machinability and moderate corrosion resistance. SS 416HT functions dependably in dry and mild chemical environments, but it is not appropriate for extremely corrosive ones.
