Anti-Scale Protective Coatings
Billets and ingots of metal are heated to high temperatures before further processes like hot rolling and hot forging. Scaling/ oxidation and decarburisation occur on these billets and ingots during heating at high temperatures. Decarburisation occurring at high temperatures leaves the metal unfit for making critical components like rails, sensitive automotive parts like leaf-springs, etc., where decarburisation needs to be maintained as low as possible. Problems due to decarburisation and scaling are:
. Metal loss of 1.5% up to 5%
. Excessive decarburisation leading to rejections
. Scale pits leading to rejections
. Reduced forging die life due to impact of hard scale on die during closed die forging
. Mill skid during hot rolling
. Damage to hearth of furnaces and induction heater refractory and coils due to scales
. Scale disposal costs and efforts
After forming, the hot rolled, forged or cast components need to be heat-treated. During heat treatment, scaling causes problems of pit marks, poor surface finish, non-uniform heating, quench cracking and increased shot-blasting / acid pickling time due to heavy scaling.
Use of ESPON anti-scale protective coatings manufactured by Steel Plant Specialities LLP ensures that scaling and decarburisation are prevented or substantially reduced.
A range of ESPON protective coatings is available for different applications. The coatings are highly customised depending on the grade of steel, heating parameters and other process specifications.

ESPON-AS Anti Scale Protective Coating for preventing scaling on forged or cast parts during heat treatment.
ESPON-AS protective coating prevents or reduces scaling on forged and cast parts during heat treatment. This results in reduced grinding and shot blasting time, reduced acid pickling time and preventing rejections due to excessive scaling.
Complex profiles like grooves and internal diameter of spindles require excessive shot blasting time and manual grinding to remove scaling.
ESPON-AS anti-scale protective coating can be applied by brushing, spraying or dipping in such locations to prevent scaling and substantially reduce shot blasting time.
This coating has no impact on heating time or temperature or properties after heat treatment of coated parts. Coating gets removed during hot quenching and subsequent shot blasting or machining operations.
ESPON-AS is non-flammable and non-hazardous.
Benefits of using ESPON-AS Anti Scale Protective Coating:
- Protects parts at heat treatment temperatures up to 1100 deg. C
- Prevents or substantially reduces scaling during heat treatment
- Reduces non-value adding operations like shot blasting / acid pickling / grinding by 40% up to 60%
- Prevents rejection of heat treated parts due to scale pits

ESPON-SR Anti Scale Protective Coating for preventing scaling on machined parts during re-heat-treatment.
Due to metallurgical reasons, heat treated and machined parts may sometimes need to be re-heat-treated. In such cases, there is little or no allowance for scaling. Even a small amount of scaling will cause rejections.
Shot blasting or grinding is not possible. In such cases, ESPON-SR protective coating is used to prevent scaling on parts during re-heat treatment. This results in prevention of scaling and prevention of rejections due to scaling.
ESPON-SR anti-scale protective coating can be applied by brushing, spraying or dipping. This coating has no impact on heating time or temperature or properties after re-heat treatment of coated parts. Coating has to be removed manualy by light buffing or such processes. ESPON-SR is non-flammable and non-hazardous.
Benefits of ESPON-SR Anti Scale Protective Coating:
• Protects parts at heat treatment temperatures up to 1050 deg. C
• Prevents scaling on machined parts during re-heat treatment
• Eliminates or minimizes post heat treatment operations like grinding, shot blasting, acid pickling, etc
• Enables to salvage the rejected components by re-heat treatment

ESPON-HR Anti Scale Protective Coating for billets and ingots during hot rolling and hot forging.
ESPON-HR is a protective coating that substantially reduces scaling on billets and ingots during heating prior to hot rolling and hot forging. Sometimes, during heating of billets in pusher-type furnaces, they get stuck to each other at high temperatures. This is also observed during induction heating of billets for hot forging. Coating only the contact surfaces of two billets with ESPON-HR has proven to prevent the problem of billet sticking. ESPON-HR anti-scale protective coating can be applied by brushing, spraying or dipping. Use of ESPON-HR Anti Scale Protective Coating ensures better surface finish of hot rolled or hot forged components. This coating has no impact on heating time or temperature of billets or ingots. Coating gets removed during hot rolling or hot forging operations. ESPON-HR is non-flammable and non-hazardous.
Benefits of ESPON-HR Anti Scale Protective Coating:
-
Protects billets or ingots at high temperatures up to 1280 deg. C. Approximately 50% to 72% reduction in scaling is possible during billet heating.
-
Prevents forging rejections due to scale pits.
-
Prevents billet sticking/ welding during heating of billets in induction heater.
-
Prevents damage to induction heater/ furnace hearth by substantially reducing scale that falls in IBH/ furnace.
-
Prevents scaling on forgings/ castings during heat treatment. Zero scaling during heat treatment achieved in many cases.
-
Enables salvaging of rejected forgings/ components where re-heating is required.
