Ashcarb-p-80 (Pack Carburising Compound)
(For Case Hardening Of Steel)
Case Hardening Of Steel
There are great many articles for which it is of vital importance that the surface hardness should be as high as possible and the wear resistance as great as practicable and that they should possess at the same time a fairly high impact strength, such articles include some kinds of gears, cams, eccentrics, wheels, etc.
Parts that are required to have a high corrosion resistance or high resistance to scaling at elevated temperatures may be manufactured either of acid resistant alloy steels or of a plain low carbon steel which is then subjected to an appropriate case hardening (chemical thermal) treatment to increase its resistance to corrosion or scaling.
To increase the surface hardness and wear resistance of machine parts the machine manufacturing industry employs carburising, nitriding, cyaniding treatments which are commonly termed as "case hardening processes".
Case hardening of steel consists in saturating the surface of a hard steel with carbon, nitrogen and certain alloying elements, such as aluminium, chromium, silicon. All these elements are diffused in the steel at elevated temperatures. the solubility of all these elements in iron increases with a rise of temperature. maximum solubility of carbon in alpha iron is about 0. 02% at 723°c whereas in gamma iron 0. 8% carbon can dissolve, and 2% at a temperature of 1130°c.
Carburising process with ashcarb-p-80 (pack carburising)
The object of carburising is to produce as hard a surface resistant to wear and other mechanical forces. It consists of saturating the surface layer of a steel article with carbon.
Articles subjected to carburising are usually manufactured of low carbon steels such as 0. 2 to 0. 25% of carbon contents. Carburising process should be adjusted so as to obtain carbon content of 0. 8 to 0. 9% and not more than 1%. with higher carbon content, the surface layer becomes very brittle because a coarse cementite net work is formed on it. In industry two methods of carburising are mainly used i. E. Pack carburising (with solid carburisers) and gas carburising (in contact with carburaceous gases). pack carburising :
Articles to be carburised are packed in close containers i. E. Pots or "boxes" completely surrounded with solid ashcarb-p-80. The packing operation requires care to ensure that sufficient compound is used to supply the carbon required. no parts, should contact the sides of tinpots. The distance between parts to be carburised as packed should be not less than 20 to 25 mm. The containers are covered after slightly tamping of carburising salt and all the openings are luted with clay in order to prevent the air from penetrating into the pot.

Generally Hydrochloric acid is used for pickling of metals. If inhibitor is not added to the acid during pickling, then it will readily attack the base metals causing heavy metal loss and sometimes even causing embrittlement of metals.
Addition of 0.1% to 0.5% of Corobit-1001 to acid pickling bath gives the following advantages :-
Reduces metal loss
Reduces acid consumption
Blistering and embrittlement of metals are minimized
Reduces acid fumes
Improves quality of pickled products
Reduces the quantity of spent liquor to be disposed off and
Decreases pickling cost

Wherever water or traces of water remain on metal surfaces, rust will start to appear usually within a few hours. Hence, to prevent this, 1% to 3% of COROBIT-ARP must be added to water so that it will give short term protection of 5 to 15 days.
COROBIT-ARP is widely used wherever water testing of pumps, valves, heat-exchangers and other pressure vessels is required.
Another use of COROBIT-ARP is after acid pickling of ferrous pipes, tubes, plates, sheets, channels and various other profiles. After pickling and subsequent water rinsing they are dipped in a 2 – 3% water solution of COROBIT-ARP to avoid flash rusting and give protection of about one week.
COROBIT-ARP is available in two Standard Packing of 10 kgs and 50 kgs.
