304 stainless steel plate surface glossy, with high plasticity, toughness and mechanical strength, acid, alkaline gas, solution and other media corrosion.
It is a kind of alloy steel that is not easy to rust, but it is not absolutely not rusty.
【Steel plate pre-delivery treatment】
304 stainless steel plate in order to ensure that all kinds of stainless steel plate yield strength, tensile strength, elongation and hardness and other mechanical properties meet the requirements, steel plate before delivery must go through annealing, solidification treatment, aging treatment and other heat treatment.
【Corrosion resistance factors of steel plate】
The corrosion resistance of 304 stainless steel plate mainly depends on its alloy composition (chromium, nickel, titanium, silicon, aluminum, etc.) and internal tissue structure, the main role is the chromium element.
【The chemical effect of chromium】
Chromium has a high chemical stability, can form a passivation film on the steel surface, so that the metal is isolated from the outside world, protect the steel plate from oxidation, increase the corrosion resistance of the steel plate. After the passivation film is destroyed, the corrosion resistance decreases.
【Oxidative acid Experiment】
For oxidizing acids, it is concluded in the experiment that 304 stainless steel has a strong corrosion resistance in nitric acid below the boiling temperature of the concentration ≤65%. It also has good corrosion resistance to alkali solution and most organic acids and inorganic acids.
