Normalizing state of delivery state of stainless steel precision tube

by:Mayer     2021-08-23
The normalizing state of the delivery state of the stainless steel precision tube The stainless steel precision tube is normalized and heat treated before leaving the factory. This delivery state is called the normalizing state. Because the normalizing heating temperature (Ac3+30~50°C for hypoeutectoid steel and Accm+30~50°C for hypereutectoid steel) is stricter than the termination temperature of hot rolling, the structure and performance of the stainless steel precision tube are uniform. Compared with the annealed steel, due to the faster normalizing cooling rate, the number of pearlite in the steel structure increases, the pearlite layer and the steel grain are refined, so it has higher comprehensive mechanical properties and is helpful for improvement The Widmanstatten structure of low carbon steel and the cementite network of hypereutectoid steel can prepare the structure for further heat treatment of the finished product. Carbon steel and composite steel are often delivered in a normalized state. Certain low-alloy high-strength steels such as 14MnMoVBRE and 14CrMnMoVB steels also require normalized delivery in order to obtain the bainite structure.
