5.Process

 EAF+LF+VD+ Forged+ Heat Treatment (Annealed,A Normalized, Q+T)

6.  Machine Capability

• Tensile strength (N/mm2Mpa): >=835
• Elongation %: >=10
• Yield strength: >=540
• Hardness: HBS<=179
• Reduction of area:>=40%

7.  Inspection

100% Ultrasonic according to the test standards:SEP1921-84,GR.3 CLASS C/C 

8.  Delivery condition

   Delivery condition: Hot-rolled,black surface.  Hot forged +Rough machined (black surface after Q/T)+ Turned (optional), Cold-drawn Conditionm, Q+T with black surface.

9. Machinability 

   Long, gummy chips characterize this alloys machinability. It can be machined in the annealed condition, however condition H1150M will yield best results. Post machining solution treatment of parts will be required prior to final hardening if machining in this condition. 

10. Welding 

  Successfully welded by common fusion and resistance methods, this alloy should not be joined by oxyacetylene welding. AWS E/ER630 filler metal is recommended if required.

11. Application

   Extrusion dies and die-casting for alumium, Mandgnesium allay mostly, for copper alloy could use mechaincal press forhing of steel
