DIE BLOCKS

Sharu special alloys supplies the best quality Hot die steels used in a multitude of applications in component manufacturing. Manufacturing Process for Die Blocks The round bars are made from ingots and are processed after giving required reduction ratio and discarding hot top and bottom for homogeneity. They are either processed by hot rolling or hot forging. These bars are further heat treated by
 Stress Relieving
 Normalizing
 Quenching and Triple Tempering
 They are also offered in
 Cut to length
 Multiple lengths

Quality Check of Die blocks
Following checks are conducted in die blocks and reported in the TEST CERTIFICATE as per customer requirement
 Surface inspection (Magnetic Particle Inspection) is carried out of each bar end to end
 Positive Material Identification using XRF to certify in process chemistry of each bar
 100% dimensional verification using calibrated verniers and Go No-Go gauges
 Step down testing
 Upset forging test
 NMIR (Non metallic inclusion rating)
 Macrostructure testing
 Microstructure phase analysis
 Grain Size
 Ultrasonic Testing for internal defects
 Radioactivity test
 Gas analysis (O, N, H)
