Our Laboratory

JF’s laboratory is equipped with appliances that are dedicated to control of incoming raw materials, in-process controls for material in production and final control once production is finished. Raw material comes from approved steel mills who undergo regular auditing and their supplies are subject to all controls by the standards in force. 

DESTRUCTIVE TESTING

  • Tensile Test
  • Proof Load Test
  • Hardness Test (Brinell – Rockwell C – Rockwell B)
  • Impact Test (From room Temperature to -196°C)

NOT DESTRUCTIVE TESTING

  • Ultrasonic Test
  • Magnetic Particle Inspection
  • Liquid Penetrant Examination
  • Positive Material Identification

Heat treatments

Hot forging and production of highly specialized material grades led JF to internally develop the heat treatment technology for the highest steel grades, alloys and non-ferrous alloys, which is performed by means of five furnaces that may reach temperatures up to 1180°. The in-house performance of this operation offers clear advantages to the customers concerning an increased control over the entire manufacturing process.JF carries out the following heat treatments totally in house: Quenching and tempering, Solution heat treatment, Normalizing, Age hardening and Tempering. All furnaces at BEA are electric type, controlled atmosphere (nitrogen or nitrogen-methanol).

By conducting these processes internally, we maintain exceptional control over the entire manufacturing process, ensuring superior quality and consistency for our customers.

This comprehensive approach guarantees that every fastener we produce meets the highest performance and durability standards.
