2. PURPOSE
To analyze various processes involved in forging Steel and
creating various products like Rollers, Discs, Pinions, Shafts etc.

3. Company Details
 Nitin Forgings and Steel Industries (NFSI) is one of the
pioneer manufacturers, stockists, and indentors of quality steel
products.
 Amajor manufacturer of large variety of carbon, alloy and special
steel forgings.
 Developing these steels which are used in earth moving
equipments, machine tools, defense, space, tools and dies,
nuclear power sector, bearings, water well rig industry, valves,
heavy machinery etc.

4. Products
 NFSI manufactures the following shapes:
 Rollers, Discs, Pinions, Shafts, Flats, Squares, Hexs, Step Shafts,
Blocks, Rings, Rounds and other shapes as per customer’s
specification and drawing.
 Product Advantage (in terms of quality):
 Better surface quality & size uniformity of products.
 Materials are forged from high integrity billets/blooms with
minimum centre segregation and perfect columnar structure.
 Ensure best possible surface finish and best possible straightness.

5. Facilities & Machines
 Clear space open air PNEUMATIC HAMMER (Capacity – 1000
kgs& 400 kgs) for Open Die Forging
 For Cutting Section:
 Double Column Semi Automatic Bandsaw Machine
 BomarErogonomic Swing ARM type Bandsaw Machine
 Horizontal Hinged type Bandsaw Machine

 Equipment used
 Conclusion

11. ANNEALING
• Annealing is a process of heat treatment wherein a material is altered, causing
changes in its properties such as hardness & ductility.
• Annealing is used to induce ductility, soften material, refine the structure by
making it homogenous & improve cold working properties.
• Annealing occurs due to the diffusion of atoms within a solid material, in
order to reach the equilibrium state.
• Recovery: Softening of metal through crystal defects.
Recrystallization: New strain-free grains nucleate & replace those deformed
by internal stresses.
Grain Growth: The microstructure starts to coarsen & may cause the metal to
have less than satisfactory mechanical properties.
• Short Cycle Annealing is used for normal ferrite into malleable ferrite.

12. QUALITY INSPECTION
 Nitin Forgings and Steel Industries is committed to provide
quality products to it’s customers.
 It has met the requirements of ISO 9001:2001 certification.
 Use of Ultrasonic Testing for:
i. Base Metal Inspection
ii. Weld Inspection
iii. Discontinuity in length determinations

13.  Various tests, like, Tension Test, Bend Test, Hardness Test, Tensile
Test, etc. are conducted on raw materials.
 Inspection is also done by third party agencies, like Lloyds
Register, Bureau Veritas, Det Norske Veritas, TUV, UHDE and
Bekhrad International Inspection Services.

16. DESPATCH
 Supplies it’s products locally.
 Transportation done through company-owned trucks.
 No intermediaries involved in transportation.
 Self- sufficient despatch system.
