Carbon steel elbow stainless steel elbow is different from different materials, contained in the chemical composition of the elbow surface will remain for a long time will not rust, does not corrode. Because the stainless steel has a good corrosion resistance, so it enables the structural member to permanently maintain the integrity of the engineering design.
A stainless steel elbow Category:
In accordance with the standard production can be reduced to:
1. Divided manufacturing standards can be divided into the GB electricity standard water standard, American standard, German standard, Japanese standard, the Russian standard, etc..
2. Production methods can be divided into a push system, pressing, forging, casting, and so on.
Characteristics of the stainless steel elbow
Stainless steel stamping elbow will not cause corrosion, pitting, corrosion or wear and tear. Stainless steel or building with one of the highest material strength metallic materials. Because the stainless steel has a good corrosion resistance, so it enables the structural member to permanently maintain the integrity of the engineering design. Chromium-containing stainless steel also set the mechanical strength and high ductility in an easy-to-parts manufacturing, to meet the needs of architects and structural designers. All metals and oxygen in the atmosphere in the reaction was carried out to form an oxide film on the surface. Unfortunately, the formation of iron oxide on the plain carbon steel to proceed with the oxidation, so that the corrosion continues to expand, the final pore formation. Paint or oxidation-resistant metal (e.g., zinc, nickel and chromium) electroplating can use to ensure that the surface of carbon steel, however, as people know, this protection is only a thin film.
The corrosion resistance of stainless steel depending on the alloying elements contained in the steel. Chromium is the stainless steel to obtain the corrosion resistance of the basic elements, when the amount of chromium in the steel up to about 1.2% chromium with the corrosive medium in the role of oxygen in the steel surface to form a thin oxide film (a self-passivating film) the base body, can prevent the steel from further corrosion. In addition to chromium, the common alloying elements as well as nickel, molybdenum, titanium, niobium, copper, nitrogen, etc., in order to meet the requirements of the various uses of the organization and performance of stainless steel.
