HEAT TREATMENT

FROM THE IDEA TO TO PROTOTYPE

Heat treatment is a controlled process used to alter the microstructure of materials such as metals and alloys to impart
properties which benefit the working life of a component, for example increased surface hardness, temperature
resistance, ductility and strength.

As a global provider of forging products, Viar has developed, applied and implemented also an extensive range of heat
treatment services. All forgings used in the manufacture of our products have to be heat treated in accordance with the
specifications applicable to the material used.

Since 10 years, Viar has developed, applied and implemented a wide range of competences and capabilities in providing heat treatment processes of forging products including case hardening, tempering, solution and ageing treatment, Specialty Stainless Steel Processes (S3P), annealing and normalizing.

Case Hardening

Case hardening is the process of hardening the surface of a metal by infusing elements into the material’s surface, forming a thin layer of a harder alloy.

Solution and age

Case hardening is the process of hardening the surface of a metal by infusing elements into the material’s surface, forming a thin layer of a harder alloy.

Annealing/Normalizing

Case hardening is the process of hardening the surface of a metal by infusing elements into the material’s surface, forming a thin layer of a harder alloy.

Stress relieving

Case hardening is the process of hardening the surface of a metal by infusing elements into the material’s surface, forming a thin layer of a harder alloy.

Hardening and tempering

Case hardening is the process of hardening the surface of a metal by infusing elements into the material’s surface, forming a thin layer of a harder alloy.

SPECIALTY STAINLESS STEEL PROCESSES (S3P)

Case hardening is the process of hardening the surface of a metal by infusing elements into the material’s surface, forming a thin layer of a harder alloy.

Ion implantation

Case hardening is the process of hardening the surface of a metal by infusing elements into the material’s surface, forming a thin layer of a harder alloy.

 

Our facilities process a wide variety of component sizes, with a combined daily capacity of about 30 tons, to exacting
standards with reliable, repeatable results. Our heat treatment operations are managed by some of the best engineers and
technicians in the industry, with the experience and expertise to provide vital support and a real understanding of
customer requirements.

Our inspection procedures exceed the industry standard and can be tailored to meet a customer’s requirement. Viar team
of on-staff metallurgists and fully operational Quality Assurance Department are ready to ensure the highest quality and
level of safety in any job. In particular, the Quality Control Laboratory, very well structured and fully equipped, is
our entity that certifies the heat treatment process.
The top quality heat treating services is also guaranteed with comprehensive periodical calibration of all furnaces and
related equipment’s.
Finally, the quality, in the Viar environmental policy, is also guaranteed and monitored through modern extraction
systems for smoke removal, reuse water cooler in addition to reset the operating noise process.
Please contact our sales department for further information.

All forgings used in the manufacture of our products have to be heat treated in accordance with the specifications applicable to the material used. No material can enter the “incoming material control area” missing the covering certificate for chemical and mechanical properties and related heat treatment diagram.

 

An ongoing and accurate check of raw materials, carefully selected and purchased from qualified suppliers only, tests and assures the perfection of the physical and mechanical features.

 

Upon acceptance of the material, a Heat Code is issued and printed on the piece to guarantee permanent identification. During all processes, inspections are not limited to visual and dimensional checks, but include all other tests specifically requested such as: heat treatment, hardness, NDE, etc.
