Heat Treatment of Steel. Heat Treatment is the controlled heating and cooling of metals to alter their physical and mechanical properties without changing the product shape. Heat treatment is sometimes done inadvertently due to manufacturing processes that either heat or cool the metal such as welding or The Difference Between Q235 and Q345 - World Scaffolding q235 hot rolled types of steel Heat treatmentApr 23, 2021 · Q235 is a plain carbon structural steel that is used throughout China. It is also known as Q235A, Q235B, Q235C, and Q235D. Since it is mild steel, it is utilized in production without heat treatment. The Q designates the yield point, and the 235 indicates the yield strength. Q345 is a steel material. It is a low-alloy steel (C <0.2%), widely q235 hot rolled types of steel Heat treatmentSteels suitable for galvanizing Nordic GalvanizersEffect of heat treatment. Cold rolled steels are usually annealed after rolling. During this heat treatment silicon near the steel surface may be oxidized. This socalled internal oxidation means that the free silicon content, that influence the reactivity during galvanizing, is lower than the mean value of the steel chemical analyses.
