Cold-Heading & Forging Quality, also referred to as CHFQ, maybe used for heading, forging, cold extrusion and other similar complex parts. Traditionally fasteners have been manufactured using the thread cutting or by hot working method. But now the trend is moving towards using the cold working process to enhance productivity and to keep the cost down. It also provides good surface finish and dimensional accuracies to the fasteners.
|Applications||Screws, bolts, nut, rivet, piston rod, ball joint stud, welding nut, ball bearing, etc.,|
|Diameter Range||1.2 - 18.0 mm|
|Raw Material Grades||JIS G3507-1, JIS G4051, C-CH1A, C-CG 10B21-10B33, CSC SPEC, S10C-58C, SAE 1005-1060, SWRCH 6A-22A, SWRCH 10K-45K|
Alloy Steel, an example of durable CHQ material contains the high performance components that meet the exacting requirements of the automotive, construction and mechanical engineering sectors. Close compositional control and quality manufacturing procedures ensure within cast variability is kept to very low levels. This delivers long-term product performance through consistent heat treatment response.
