Forged Hot Work Tool Plate 1.2344/ H13 For Tool
1 Introduction
AISI h13 modified form toughness high strength high quality hot working die steel,
H13 is a hot work die steel, which is a steel grade formed by adding alloying elements to carbon steel.
HSSD H13 steel has good thermal stability and thermal fatigue resistance, replace the imported high quality senior hot die steel, for example: AISI H13, 1.2344 etc.

5 Heating treatment
Quenching | Tempering |
Heating Temperature/ºC | Cooling | Hardness/HRC | Heating Temperature/ºC | Cooling | Hardness/HRC |
850-800 | Air | 50-52 | 580-640 | Air | 28-36 |
6 Characteristics
1). High resistance of tempering softening properties(the using temperature can improve 50ºC, than that of H13 steel)
2). Excellent thermal stability: heat preservation in the long time of 620ºC, the hardness is always higher than that of h13, and still maintain in 35 hrc above.
3). Excellent thermal fatigue resistance: the thermal fatigue resistance of sd h13mod is better than that of h13 steel.
4). Characteristic curve of tempering and cct curve.
7 Application
a.Full hardness (52-54HRC) plastic moulds with high polishing and long lifetime requirments, such as bakelite plastic mould.
b. Lead,Zn and Al alloy die casting moulds, such as engine radiater, lights and other decorative products
c.Aluminum extruded moulds, such as aluminum window frame, computer radiater.
d.Hot forging moulds, such as auto connecting rods, crank, stainless dinner knife.
e.Cu alloy extruded and die casting moulds.
f. Casting moulds,extruded moulds,,forging moulds.
Company Profile
Guangzhou ChangFeng Steel Co., Ltd, is located in Guangzhou city, it was established in 2012, and is an Professional import and export company with ten years experience of selling special steel, which mainly sells plastic die steel, hot work die steel, cold work mould steel, alloy structural steel, bearing steel, tool steel, stainless steel, carbon steel, etc.
We also act on behalf of exporting steels of mainly steel factories in China, including Baogang group, Shagang group, Wenfeng group, Xingcheng group, Dongte group, Daye and so on. We are full of export experience to the market all over the word, such as America, Germany, France, Italy, Turkey, Singapore, Thailand, Malaysia, Vietnam, Taiwan, and Middle-East.
At the same time, We offer the seamless steel pipe, welded carbon steel pipe, GI pipe, and special pipe. Fittings elbow, tee, reducer, cap, lap joint, flanges etc...This is better for our customer to buy the different products from China, while they are saving their time, but they can enjoy in our best serves.
