Calcium in Steels Calcium (Ca) (atomic number 20 and atomic weight ) has density of gm/cc. Melting point of Ca is 842 deg C and boiling point is 1484 deg C. Ca additions are made during steel making for refining, deoxidation, desulphurization, and control of shape, size and distribution of oxide and sulphide inclusions .
A ranking of the tested stainless steel grades according to their corrosion resistance in sodium chloride brine solutions was: UNS S31603 < UNS N08904, UNS S32205 < UNS S31254, UNS S32750 < UNS ...
Its solid form is corrosive to aluminum at relative humidity and normal temperatures. Its solutions are not corrosive to other common metals, like stainless steel, carbon steel, nickel cast iron, nickel and nickelbase alloys. Sodium carbonate solutions also attack .
Selection of stainless steels for handling sodium hydroxide (NaOH) Introduction. Sodium Hydroxide (Caustic Soda) is a strong base. It is used in metal degreasing and cleaning processes in a wide range of industry applications. Stainless steels types 304 and 316 can be considered resistant below 80 degC, up to the limit of solubility.

Apr 24, 2009· Applied basics of sodium cyanide case hardening for steel. Q. I work as a managing engineer at a concrete block plant located in central Mexico. My degree is in industrial engineering and I did some graduate studies in the US in mechanical engineering. Right now I am facing the problem of having to make our own block molds in order to save money.

After thorough cleaning, the stainless steel part or component is ready for immersion in a passivating acid bath. In current practice, any one of three approaches can be used – nitric acid passivation, nitric acid with sodium dichromate passivation and citric acid passivation. Which bath and composition to use depends on the grade of ...
In its dried state, sodium chlorite (NaClO 2 ) is a white or light yellowgreen solid. The greenish tint comes from trace amounts of CdO2 or iron, which are production residuals. Sodium chlorite has a molecular weight of and decomposes at about 392°F (200°C).

Influence of Alloy Composition. The resistance of a stainless steel to localized attack is strongly related to its alloy content. The primary elements that contribute to the pitting and crevice corrosion resistance of austenitic and duplex stainless steels are chromium (Cr), .
The duplex stainless steel with their dual austenite/ferrite microstructures has a resistance that is in between that of the austenite and ferrite grades. Corrosion Testing. The relative resistance of a stainless steel to chloride SCC is often quantified by the use of standard boiling salt solutions.

We use a stainless steel machine (316SS), and we have had recent problem of green coloration in our products. We think it could be due to a previous preparation where we used 10% sodium chloride solution which could have done some corrosion to the stainless steel.
Housings and frames can be furnished in all stainless steel, aluminum or Monel. The exact grade of metal used depends on the nature of the installation. Unless otherwise specified, #304 housings will be furnished when stainless steel is ordered. #316 stainless steel is also available. All Hartzell fans and blowers for corrosive applications

Sodium hydroxide is a popular strong base used in industry. Around 56% of sodium hydroxide produced is used by industry, 25% of which is used in the paper industry. Sodium hydroxide is also used in the manufacture of sodium salts and detergents, pH regulation, and organic synthesis.
Chromium increases the corrosion resistance of steel, and a minimum of 12% chromium is necessary to produce a stainless steel. The best known of the stainless steels contains about 74% iron, 18% chromium and 8% nickel (known as 188 stainless). Stainless steel is perhaps most familiar as kitchenware (sinks, kettles and cutlery).
Commercially concentrated Sodium hypochlorite is around 15wt %. bleach solutions are around % sodium hypochlorite. Corrosion resistance of stainless steels. The hypochlorite ion (OCl) is aggressive to stainless steels, acting in a similar way to wet chlorine gas, and like the chloride ion (Cl), is a dangerous pitting corrosion ...
