Seamless Steel Pipe The Image Of Modern Materials

 Seamless Steel Pipe is a very special metal jewelry, texture is very tough, but very resistant to corrosion, it will not be like silver will be black, it will not like copper jewelry like allergies, but not like alloy jewelry because Lead and toxic, and stainless steel jewelry always at room temperature for life to maintain their own color. Stainless steel jewelry from the inside to the outside of the same material, and through the artificial sweat body test, its characteristics, completely non-corrosive, and resistant to strong acid, alkali resistance, do not change color, not fade, not allergies, no deformation, hard, bright. Is completely on the human body will not produce any side effects and no harm to the green high-end green jewelry.

Seamless Steel Pipe The corrosion resistance of stainless steel ornaments depends on the alloying elements contained in the steel. Chromium is the basic element to obtain corrosion resistance of stainless steel, when the chromium content of steel to about 12%, chromium and corrosive media in the role of oxygen in the steel surface to form a thin layer of oxide film (self-passivation film) , Which can prevent further corrosion of the steel substrate. In addition to chromium, the commonly used alloying elements are nickel, molybdenum, titanium, niobium, copper, nitrogen, etc., to meet the various uses of stainless steel structure and performance requirements. Its corrosion resistance, toughness and weldability with the increase in chromium content increased resistance to chloride stress corrosion resistance is better than other types of stainless steel. Stainless steel is a modern material with more than 60 years of development. Since the beginning of the stainless steel jewelry in recent years, stainless steel put the image of modern materials and jewelry applications in the excellent reputation in one, as long as the steel selection is correct, appropriate processing, maintenance Appropriate, stainless steel jewelry will not produce corrosion, pitting, corrosion or wear, so that its competitors envy.

Seamless Steel Pipe Stainless steel will not produce corrosion, pitting, corrosion or wear, with corrosion resistance, enhanced strength, deformation of steel is not easy to break and environmental performance, easy to rust. Suitable for harsh environments (wet, acid and other indoor and outdoor environment) under the use of some public environmental hardware facilities, and the surface if the spray coloring, will make the adhesion strength higher, but after the surface zinc damage corrosion resistance disappeared.

Since the beginning of this century, since the invention of stainless steel, stainless steel put the image of modern materials and architectural applications in the excellent reputation in one, so that its competitors envy.

    As long as the steel selection is correct, the processing is appropriate, the maintenance is appropriate, the stainless steel does not produce corrosion, pitting, corrosion or wear. Stainless steel or building materials used in the highest strength of one of the materials. Because stainless steel has good corrosion resistance, it allows the structural parts to permanently maintain the integrity of the engineering design. Chromium-containing stainless steel also combines mechanical strength and high elongation in one, easy parts of the manufacturing, to meet the needs of architects and structural designers.

 In the construction, building and structure of the industry, the key to the success of stainless steel is its good corrosion resistance.

 Seamless Steel Pipe Why is corrosion resistant stainless steel?All metals react with oxygen in the atmosphere to form an oxide film on the surface. Unfortunately, the formation of iron oxide on ordinary carbon steel continues to oxidize, so that corrosion continues to expand, and ultimately the formation of holes. The surface of the carbon steel can be secured by painting with paint or oxidation resistant metals (eg zinc, nickel and chromium), but, as is known, this protection is only a film. If the protective layer is damaged, the following steel will begin to rust.

The corrosion resistance of stainless steel depends on chromium, but because chromium is one of the components of steel, so the protection method is not the same.

Seamless Steel Pipe When the chromium content is 10.5%, the atmospheric corrosion resistance of the steel is significantly increased, but the chromium content is higher, although the corrosion resistance can be improved, but not obvious. The reason is that when the steel is alloyed with chromium, the type of surface oxide is changed to a surface oxide similar to that formed on pure chromium metal. This tightly adhered chromium-rich oxide protects the surface from further oxidation. This oxide layer is extremely thin, through which it can see the natural gloss of the steel surface, so that stainless steel has a unique surface. Moreover, if the surface damage, the exposed steel surface and the atmosphere will be self-repair, re-formation of this "passive film", continue to play a protective role.
