The characteristics of high temperature resistant stainless steel pipes are due to the high content of nickel (Ni) and chromium (Cr), which has good high temperature resistance, corrosion resistance, acid and alkali resistance, and high temperature resistance. High temperature resistant steel pipes are specially used for manufacturing electric furnace tubes and other occasions. Specifications for high temperature resistant stainless steel pipes, A573 Grade 58 plate manufacture, high temperature resistant stainless steel pipes for finish-rolled and cold drawn seamless pipe specifications: outer diameter 6mm---940mm; wall thickness 0.8mm---60mm.
Quenching and tempering (QT) is a double heat treatment process of quenching and high temperature tempering. In general, medium carbon steel and medium A573 Grade 58 plate manufacture carbon alloy steel often need quenching and tempering treatment. Quenching and tempering can make iron and steel parts obtain a good combination of strength and toughness, with high strength, excellent toughness, plasticity, cutting performance, etc. Some A573 Grade 58 plate manufacture alloy steel or low alloy steel must be quenched and tempered to obtain good comprehensive properties. These steels can also be called quenched and tempered steels.
