Alloy steel pipe fittings are essentially made of carbon, manganese, chromium, molybdenum, and trace elements. Chromium enhances oxidation and corrosion resistance, and molybdenum increases high-temperature strength and creep resistance. These fittings usually provide yield strengths from 205 to 450 MPa and tensile strengths from 415 to more than 620 MPa, based on the grade. Normalizing, quenching, and tempering heat treatment processes increase their toughness as well as fatigue strength further. Such a combination of strength with resistance to heat makes alloy steel suitable for pressure piping systems operating under harsh conditions.
