Heat treatment

Delivery status: Brinell hardness HBW10 / 3000 (less than or equal to 235)


Quenching: 790 degrees ± 15 degrees preheating


1000 degrees (salt bath) or 1010 degrees (furnace control atmosphere) ± 6 degrees heating


Insulation 5 ~ 15min air cooling


550 degrees ± 6 degrees tempering annealing, thermal processing

 

 

Chemical heat treatment

Mold can be further strengthened If use gas nitriding or nitrocarburizing, but the nitriding temperature should not be higher than the tempering temperature, in order to ensure that the strength of the heart does not reduce, thus enhancing the service life of the mold.

 

 

Delivery condition

EF, or ESR, Hot rolled or forged, black surface or milling

 

Hardness: annealed to HB≤229

 

 

Usage

H13 is the introduction of the United States H13 empty hardening hardened hot for die steel. Its performance, use and 4Cr5MoSiV steel is basically the same, but because of its higher vanadium content, so the temperature (600 degrees) is better than 4Cr5MoSiV steel, hot work die steel is widely used in a representative steel.

 

 

Applications

1. Cu alloy extruded, die casting moulds.

2. Aluminum extruded moulds (such as Aluminum window frame, computer radiator).

3. Hot forging moulds (such as auto connecting rod, crank, stainless dinner knife).

4. Lead Zn and Al alloy die casting moulds (such as engine radiater, lights ang other decoration products).

5. Full hardness (52-54Hrc) plastiy moulds with igh polishing and long lifetime requirements, (such as bakelite plastic mould).

Hardness analysis
The carbon content in the steel determines the hardness of the quenched steel substrate.

 

According to the curve of the carbon content in the steel and the hardness of the hardened steel, the quenching hardness of the H13 die steel is about 55 HRC.

 

For tool steels, a portion of the carbon in the steel enters the matrix of the steel causing solid solution strengthening. The other part of the carbon will combine with the carbide-forming elements in the alloying elements into alloy carbides.

 

Hot work flat steel bar, in addition to a small amount of this alloy carbide residue, but also requires it in the tempering process quenched martensite matrix precipitated twice hardening phenomenon.

 

The properties of hot work tool steel are thus determined by the organization of uniformly distributed residual alloying carbon compounds and tempered martensite.

 

Thus, the content of C in steel can not be too low.
