Stainless steel elbow

Stainless steel elbows differ mainly from carbon steel elbows in material, its chemical composition will maintain the elbow surface for a long time will not rust, will not be corroded.

Stainless steel elbow will not cause erosion, pitting, rust or abrasion. Stainless steel is still one of the materials with high strength in building metal materials. Because stainless steel has good corrosion resistance, so it can make structural parts to maintain the integrity of engineering design for a long time. Stainless steel stamping elbow with chromium also integrates mechanical strength and high elongation. It is easy to manufacture parts and meets the needs of architects and structural designers. All metals react with oxygen in the atmosphere and form oxide films on the surface. Unfortunately, the iron oxide formed on ordinary carbon steel inherits and oxidizes, causing corrosion to expand and form pores. Carbon steel surfaces can be plated with paint or oxidation-resistant metals (such as zinc, nickel and chromium), but, as is known, this protection is only a thin film. In addition, after pushing the head, the front end diameter is usually large. The whole die is actually a press. There must be a set of molds, 2.5 arcs, one up and down. The outer diameter after finishing has reached the size requirement of the finished product. Wall thickness has been controlled since the wall thickness of the material has been controlled. The thickness tolerances of elbow and pipe are the same, all of which are + 12.5%. In addition to chromium, the commonly used alloying elements are nickel, molybdenum, titanium, niobium, copper, nitrogen and so on, in order to meet the various uses of stainless steel stamping elbow structure and function requirements.

Stainless steel elbow resistance to air, steam, water and other weak corrosive media and acid, alkali, salt and other chemical corrosion media corrosion of steel. Also known as stainless acid resistant steel. In practical application, steel resistant to weak corrosion medium is often called stainless steel stamping elbow, and steel resistant to chemical medium is called acid-resistant steel. Because of the difference in chemical composition, the former is not necessarily resistant to chemical corrosion, while the latter is generally stainless. Chromium-containing stainless steel elbow also integrates mechanical strength and high elongation in one, easy to manufacture components, to meet the needs of architects and structural designers. All metals react with oxygen in the atmosphere and form oxide films on the surface. Unfortunately, iron oxide formed on ordinary carbon steels continues to oxidize, causing corrosion to expand and form cavities. Carbon steel surfaces can be plated with paint or oxidation-resistant metals (such as zinc, nickel and chromium), but, as is known, this protection is only a thin film. The corrosion resistance of stainless steel elbow depends on the alloy elements contained in the steel. Chromium is the basic element for stainless steel stamping elbow to obtain corrosion resistance. When the content of chromium in steel reaches about 1.2%, the interaction between chromium and oxygen in the corrosive medium forms a very thin oxide film (self-passivation film) on the steel surface, which can prevent further corrosion of the steel matrix.
