Introduction of corrosion resistance of 904L stainless steel pipe

In strong oxidizing nitric acid, compared with high alloy steel containing molybdenum, low corrosion resistance. In hydrochloric acid, the use of 904L stainless steel pipe is limited to a lower concentration of 1-2%. In this concentration range. The corrosion resistance of 904L stainless steel pipe is better than the conventional stainless steel. 904L stainless steel pipe has a high resistance to pitting ... Read More »

The difference between cold-rolled stainless steel angel bar and hot rolled stainless steel angel bar

What is the difference between rolling stainless steel angel bar and hot rolled angel bar? Cold-rolled stainless steel angel bar and hot rolled stainless steel angel bar is respectively using two different rolling cold rolled and hot rolled and rolled stainless steel angel bar. The difference between the two is: 1, the stainless steel cold rolling forming angel bar to allow local ... Read More »

How to improve the corrosion resistance of stainless steel tube

How to improve the corrosion resistance of the stainless steel tube, yaang pipe industry knowledge to provide the following for your reference: There are many method to improve corrosion resistance of stainless steel tube, such as surface coating a layer of corrosion resistant metal, coating nonmetal layer, electrochemical corrosion protection and change of environmental media, etc. But using the alloying method, ...

What reason is 316 stainless steel angle bar rust?

316 stainless steel angle bar as matrix is beyond 60%, for complex high alloy steel, nickel, molybdenum and other alloying elements, its biggest characteristic is corrosion resistant ability strong, but not rust stainless steel is not absolute. In coastal areas, or some severe air pollution in local truly, when the chloride ion content in the air is larger, disclosed in stainless ... Read More »

Seamless steel pipe, hot tension reducing mill steel pipe, straight seam steel pipe what’s the difference between the three of pipe

Seamless steel pipe market competition at present, due to the limitation of its production process, the production cost of seamless steel tube has been high, resulting in the gradual decline in its economic benefit. As China’s metallurgical industry technology progress, instead of the seamless steel tube ­ new products also emergence, so new product whether meet the indicators of seamless steel ... Read More »

Why not easy to corrode stainless steel pipe?

Why not easy to corrode stainless steel pipe? All metal and atmospheric oxygen in the reaction, formed in the surface oxide film. Unfortunately, in the ordinary carbon steel pipe on the formation of the oxidation iron oxide continue, kept expanding rust, eventually forming holes. Can use paint or resistant to oxidation of the metal (for example, zinc, chromium and nickel) on plating ... Read More »
