Principal Design Features
|
|
This alloy is one of the Hot Work, Chromium type tool steels.
|
|
|
Applications
|
|
H19 is employed in applications requiring extremely high shock and abrasion resistance even at elevated temperatures. Commonly used in hot die and extrusion inserts for brass, aluminum, etc..
|
|
|
Machinability
|
|
H19 is rated at 60% of a 1% carbon steel, or 40% of a B1112 steel.
|
|
|
Welding
|
|
Preheat to 950 F prior to welding and do not weld below 650 F. The alloy is successfully welded using shielded arc methods. For best results, fully anneal work prior to further machining or forming.
