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.

Ashtreat-CYNOF

(Cyanide Neutraliser)

Introduction:-

Ashtreat-CYNOF is a highly alkaline product used for neutralising cyanide content in effluent waste arising from electroplating shop and heat treatment shop.  By using Ashtreat-CYNOF  the cyanide level can be effectively brought down to 0.1 ppm which is below the acceptable limit of pollution control boards.  This treated effluent can thus be safely discharged into the sewage.

Advantages:-

1.      Ashtreat-CYNOF reacts with cyanides to form final compounds of carbon dioxide, nitrogen gases and non-hazardous sludge which can be safely and easily disposed without creating any pollution hazard.

2.      It reduces the cyanide level below 0.1 ppm of the effluent, which is well within the permissible limits.

3.      Ashtreat-CYNOF is highly alkaline, thus pH control is not required.

4.      Ashtreat-CYNOF is non toxic and causes no rise in temperature during treatment.

Directions:-

1.      Check the cyanide content of the waste effluent.

2.      In case of waste effluents from Electroplating shop, pH value of the solution should be checked first.  If it is found acidic then the same should be brought to pH 11.5.  This is important.

3.      Then calculated amount of Ashtreat-CYNOF is added slowly and continuously depending on the cyanide content in the effluent. Stirring or Aeration will help to reduce treatment time.

4.      Treatment time should be minimum 120 minutes, before discharging effluent in sewage.

5.      After completion of above treatment, titration of 10 ml of treated effluent waste should be carried out to ensure that cyanide content is well within permissible limits.

Notes:-

1.      Lime should not be added to raise the pH of the effluent as this may give rise to heavy sludge formation which can trap cyanide radicals. This living cyanide will go undetected during testing and unattacked during treatment and will go into the sewage along with treated effluent.

2.      To avoid evolution of toxic fumes, the pH of effluent should be maintained above 11.5, and the temperature below 30°C, at all times.

Ashok Industry are manufacturers of Corobit-1001 which is a very efficient corrosion inhibitor for acid pickling bath.

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 :-

1. Reduces metal loss

2. Reduces acid consumption

3. Blistering and embrittlement of metals are minimized

4. Reduces acid fumes

5. Improves quality of pickled products

6. Reduces the quantity of spent liquor to be disposed off and

7. Decreases pickling cost

Corobit-1001 is also widely used as an inhibitor for acid descaling of boilers and heat exchangers to suppress attack on metals.

Ashok Industry is an ISO 9001-2008 Certified Company.

Ashok Industry are manufacturers of COROBIT-ARP which is a water soluble chemical compound in powder form. It is used to give temporary protection to ferrous components and surfaces against rust and corrosion.

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.

Anticarb-psl

 (anti-carburising paste for gas carburisation)

Anticarb-psl is specially compounded for selective carburisation of metal surfaces as the paste protects some surface areas which are not to be carburised. Selective carburisation is carried out on surfaces where the wear resistance is necessary on certain areas with high ductility on other areas. It provides a better compromise of a hard abrasive resistant surface associated with highly ductile zone.

Uses :

Anticarb-psl is used for selective carburisation of various metallic parts such as diesel engine components, crane-shafts, gears, bearings, threaded parts, cutting tools, defence components, etc.

Method of application :

Anticarb-psl is a paste which can be applied either by brush, spray or dipping. Water may be used for thinning. Excessive thick coatings should be avoided as it is not only uneconomical but coatings are also prone to cracking. On an average a coating thickness of 0. 5-1 mm is most effective.

Drying :

After application, the parts should be left to dry by suspending in a well ventilated area, preferably in a warm atmosphere. Drying time will vary from 30-60 minutes, and is dependent on the temperature of part and atmosphere.  Drying time will also depend on the thickness of the coating.

Handling :

After the paste is completely dry, the parts should be put in the furnace. Care should be taken at all times to prevent any damage to the coating.

Coating removal :

The best method for removing residual coating after heat treatment is by mechanical action either by wire brushing, sand blasting or manual scraping. Most of the coating however, may get dislodged at the quenching stage itself. High-pressure jetting of a caustic soda solution also facilitates easy removal of the residual coating.

Notes :

1. Always keep the containers tightly closed when not in use.

2. Should the paste get dry in the container, a little water should be added and mixed well.

3. If thinner consistency or coatings are desired then water may be used as a diluent.

4. Cleaning of hands, brushes, etc. Should be done with soap and warm water.
