Annealing:
Before the heat treatment processing is annealing temperature is 870 ~ 880 degrees, heat preservation of 2 ~ 3 hours, 800 degrees and 800 a, 1270 from a 1280 - degree interrupted quenching, sizing temperature for 580 a, 620, then 560 degrees to three tempering, tempering heat preservation for 1 hour.
Forging:
High speed steel is easy to burn when heated, and it is easy to break the forging in this temperature range, and strictly control its heating temperature.
Quality Condition:
1. Both end of each bar must be cut
2. Ladle furnanced and vacuum de-gassed
3. Show heat No. on each bar
4. Surface condition the surface of the hot rolled square bar shall befree cracks, scar and wrinkles that affect the use of the billets. In case there is the above-mentioned defect, it shall be remove.
5. The mill test certificate shall show the chemical composition, and it is guaranteed that the chemical composition shall be within the limit stipulated in the contract.
