Product Description

Description
NOS415 Die Steel, 1.2344 ESR Modify

Features

NOS415, originates from SUPER technology and is a type of hot work tool steel with high purity, homogeneous annealing structure, no large-sized eutectic carbides, excellent overall performance.
NOS415 is applied for making various kinds of hot working dies, such as die casting, hot extrusion, hot forging,
and hot stamping. It also can be used for making some plastic moulds because of its high mirror polishing performance.
NOS415 is strictly inspected as per standard NADCA#207-2011, and other properties also can be tested as customers' requirement.

Take the advanced melting process for smelting and refining to get the super purified and homogeneous steels.
 
Take the advanced 3D forging technology to thinning the structure; eliminate the internal defect like shrinkage cavity
and porosity; break the big-sized carburization and reduce the band segregation. It is helpful to reduce the discrepancy in the different directions of the steel.
 
Take the advanced Super-fining heat treatment technology to get the small grain size and homogeneous structure.
 
Take the strict inspection for each piece of steel products according to the most advanced standard. Ensure our customers use the steels with excellent and stable quality.

Heat Treatment
Soft Annealing
Heating steels upto 850ºC in protective atmosphere; after soaking, then have cooling in the furnace at the rate of 10ºC/hr; after temperature comes down to 650ºC, finally have air cooling.
           
Stress relieving
Stress Relieving should be done on the die after rough machining, heating upto 650ºC, heat preservation for 2 hours; Slow cooling down to 500ºC, further air cooling.
 
Hardening
Refer to Hardening Diagram,
Preheating in two steps as per A: 650ºC and B: 850ºC
Austenization as per C: 1020-1050ºC
Direct cooling as per D, or Sectionalized cooling as per F:500-550ºC
 

              Hardening Diagram                Tempering Diagram
 
Tempering
Refer to Tempering Diagram. Choose the proper tempering temperature and holding time for required hardness.
Tempering temperature F over 550ºC, holding time at least 2 hours.
After tempering, it must need cooling down to room temperature. Temper at least 2 times.
Tips: To avoid the temper brittlement, don't temper in 425-550ºC.
 Hardness: HRC                                       Residual Austenite %

      Tempering Temperature (2h+2h) ºC
 
Tips
1. Holding time means the duration of die steel from total heating to Austenitization.
2. During hardening process, steel must be heated to avoid oxidation or decarburization.
3. Steels need to be tempered immediately when temperature gets down to be 50-70ºC.
4. To get excellent property for the die, the quenching speed should be as fast as possible,    
    but should avoid the case of being out of shape or cracks.
 
If you need more details, please refer to "Heat Treatment Manual" or consult us.

Steel Grade Recommendation

Die Casting

Die Casting is a kind of metal casting technique. It is characterized by using the mould cavity to have high pressure on molten metal. It has the good performance in anti heat cracking, anti corrosion, anti-crack, red hardness.
