is the process by which a wear resistant hard surface is deposited onto
a component by welding in order to increase its useful life. Hardfacing
is carried out when equipment parts are to be subject to abrasion,
corrosion or impact at room or elevated temperatures, in order to
improve the part’s wear resistance, strength and hardness thus
increasing efficiency. Moreover, hardfacing keeps the parts in better
condition, reducing part replacement, power consumption, and equipment
and Nickel Base Alloys.
to be most versatile of hardfacing alloys, cobalt and Nickel based
alloys are specially formulated to resist a wide range of hostile
environments including abrasion, corrosion, galling, oxidation and
erosion, They are able to maintain their hardness at temperatures of up
to 1500O F (800O C) and have been proven to be
useful in industries ranging from aerospace to petro chemical.
range of applications :
special properties of these compounds make them valuable across a wide
range of Industrial Applications. The oil & petroleum, nuclear,
plastics, steel and metal processing industries rely on them, as do
glass bottle and ceramic manufacture. Quarrying, mining, earth-moving
and construction, timber and the wood-pulp industry all find hardfacing
alloys essential to their day to day equipment reliability and long term
Base Puddle torch metal surfacing Powders:
different grades of Nickel Alloy Powder satisfy the application
requirements of the customer using spray / fuse
equipment. The precisely
controlled particle distributions are designed for efficient results
with the popular type of equipments. Each grade gives a specific narrow
range of nominal hardness in fused deposit. Grades are available with
hardness ranging from 16 HRC to 60 HRC.
our Nickel Base Hardfacing powders are manufactured from high quality
raw materials. These powders are designed with excellent spraying
characteristics and bright, glassy slickups. Coatings are clean, dense
and trouble – free. All powders assures surface hardness, high deposit
efficiencies, resistance to heat and corrosion, uniform spray pattern
and fusing response.
Base Bare Rods (Stellite)
are popularly known as “Stellites” are used as corrosion and
oxidation resistance coatings on various applications. The coatings are
applied by TIG, and Oxy – Acetylene welding processes. Stellite
deposits hardness varies from 27 HRC (Alloy 21) to 62 HRC (Alloy 190).
