Hot Rolled Plastic Mold Steel Plate 1.3355 / T1 For Making Cutting Tools
|Flat Bar Size(mm)||Round bar Size(mm)|
1,High hardness, high red hardness and high temperature hardness, easy to grinding.
2,The application of the tool to work at a temperature of 600℃ can still keep cutting performance, such as vehicles, planing, milling, reaming, broach, drill, tap, die cutter and gear etc.
3,Suitable for processing soft or medium hardness (less than 300 ~ 320HB) material and making high temperature wear-resistant machine parts.
Tool industry: scraper, hobbing knife, iron knife, drill etc.
Small cut tool with complex shape.
Recommend heat treatment:
|Heating temperature/℃||Cooling way||Hardness (HRC)||Tempering temperature/ºC||Tempering number||Hardness
|First preheating||Second preheating||Last heating|
Packed with plastic film, seaworthing packing, others according to customers' requirements;
For abundant stock, 15-20 days.For customized products, 30-50 days.
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.
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.
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.
