Stainless Steel Seamless Pipe Exports In 2023, after two years of growth, there was significant decline in shipments abroad of stainless steel seamless pipe for oil and gas, when their volume decreased by -16.7% to 15K tons. Over the period under review, exports, however, saw a buoyant increase. ...Read more »

The downstream customers’ effective demand was insufficient. At the same time, affected by factors such as increasing international trade pressure and total energy consumption restrictions, the stainless steel pipe industry faced great production and operation pressure. Wujin Stainless Stee...Read more »

The characteristics of HCI are similar to those of dry CI. There is also a critical temperature that causes the corrosion rate of metal materials to increase sharply. For some corrosion test data, see Table 2-27, Table 2-28, and Table 2-29. Combining these corrosion data, it can be considered tha...Read more »

HF gas is a common medium for certain chemical processing. In high temperature hydrogen fluoride, Ni201, monel400, inconel 600, C-276 and 00Cr16Ni65Mo2Ti alloys all have suitable corrosion resistance, and have been successfully applied to practical engineering. Some corrosion test data are shown ...Read more »

Fluorine is the most powerful and most active halogen element. Its strongest oxidation potential makes it form compounds with all common elements. This property determines that it can react directly with the metal to form metal fluorides. The properties of the fluoride protective film are directl...Read more »

In caustic, universal austenitic stainless steels can only be used below 100oC in concentrations below 50%. Nickel and its corrosion resistant alloys exhibit excellent resistance to caustic alkali corrosion, and the corrosion resistance of the alloy increases as the nickel content increases. Prac...Read more »

Corrosion in Organic Acids The corrosiveness of organic acids is not strong. Corrosion test data in formic acid, acetic acid, and propionic acid show that Ni200, Monel400, and nickel-base and iron-nickel-based corrosion-resistant alloys containing Cr, Mo all show excellent results in boiling solu...Read more »

In chemical processing, mixed acid media are often encountered. The corrosion behavior of corrosion resistant alloys in mixed acid media depends on the type of mixed acid, the concentration of acid, and the temperature of the solution. The temperature of the mixed solution of the two reducing aci...Read more »

The corrosion resistance of nickel-based and iron-nickel-based corrosion resistant alloys in nitric acid depends on the chromium content of the alloy. The higher the chromium content in the alloy, the better the corrosion resistance. G-30 alloy and 690 alloy exhibit the best corrosion resistance ...Read more »

Phosphoric acid is a kind of reducing inorganic acid, also called non-oxidizing acid. Its corrosiveness to the material depends on the type of phosphoric acid. Phosphoric acid and wet-process phosphoric acid are two types of phosphoric acid currently used in industrial applications. The former is...Read more »

HF acid is a reductive inorganic acid widely used in chemical processing. The industrially applicable HF acid concentration ranges from 30% to 70% HF aqueous solution and anhydrous HF. Although chemically classified, HF acid is a weak acid relative to hydrochloric acid and sulfuric acid, but its ...Read more »

Hydrochloric acid is one of the most aggressive corrosive reducing acids, and its corrosion to metal materials was a major technical problem that the corrosion resistant structure was difficult to solve. The corrosion rate of industrial pure nickel 200,201 and nickel-copper alloy Monel 400 in roo...Read more »

Overall corrosion: Full corrosion can occur in acids, salts, aqueous alkalis, and some corrosive gases. When the composition of the alloy is confirmed, the two dominant factors affecting its overall corrosion resistance are material and environmental effects. Material factors are heat treatment a...Read more »
