Accreditations & Certifications

Inspection Facilities

• Material Inspection: Verification of raw material integrity and compliance with specifications.
• Product Inspection: Comprehensive dimensional and surface evaluations at multiple production stages.

Laboratory Capabilities

• Chemical Tests: Conducted using advanced spectrometers to ensure exact chemical composition.
• Physical Tests: Strength, toughness, and ductility testing under controlled conditions.

Non-Destructive Examination (NDE)

• Techniques such as Magnetic Particle, Dye Penetrant, and Ultrasonic Testing ensure internal soundness and defect-free forgings.

Gas Control in Ingots:

Hydrogen ≤ 2 PPM, Nitrogen ≤ 90 PPM.

Oxygen levels certified at:

• 25 PPM (max) for low-carbon grades
• 20 PPM (max) for medium carbon and alloy steels
• 15 PPM (max) for high-carbon grades (e.g., ball bearing steels)

Forging Ratio:

Both upset and drawing forgings are performed, maintaining a minimum reduction ratio of 4:1, with higher ratios achieved depending on ingot size and final geometry.

Heat Treatment Facility:

MIFL operates a fully automated, PLC-controlled heat treatment shop with:

• Gas-fired furnaces for slow cooling, hardening, and tempering
• Two quenching tanks (water and oil) with agitation and temperature control
• SCADA-based monitoring and digital recording of heating cycles for precision traceability

Our QA department ensures full traceability and consistent mechanical integrity through the following tests:

• Internal Soundness: Guaranteed up to 2mm FBH (finer as per client request)
• Hardness: 30 BHN range (20 BHN for special cases)
• Dimensional Tolerance: +3 / –0 (unless otherwise specified)
• Grain Size: Typically ASTM 6–8, with fine grain structure guaranteed up to ASTM 5–8
• Chemical Composition: Controlled with restricted chemistry for precision carbon, manganese, chromium, and nickel levels
• Inclusion Ratings: ASTM E45, not exceeding 1.5 (A–D) thin & thick series
