Domestic S136 bar! However, if you want to really Fushun's S136, I have been requisitioning for Jianyi Mold, they specialize in imported materials and domestic Fushun materials, and their factory is very large!

2083 is corrosion-resistant mirror mold steel and the American standard is 420

The hardness is around HRC: 50-55.

Chromium-containing stainless steel Good acid resistance and polishing properties Extremely wear-resistant after hardening Suitable for acid plastics and die steels that require good polishing.

You ask him what he is mainly for, if it is just a requirement for hardness, just take a better 3cr2mo. If he has a very low pressure, take P20. The cheapest P20 is only 8 yuan. I don't know if you reported it?

2083 die steel is a special steel from Germany Buderus, plastic mold steel, which is a high CR stainless steel, with a CR content of more than 15, with very excellent wear resistance, good acid and polishing performance, and good machinability.

Information**.

It is generally divided into cold work die steel, which is equivalent to the domestic brand of 5CrNi4Mo, as for what can be replaced, the key depends on your use. Generally, if it is used for cold molds, it can be replaced by D2, DC53, etc., according to the composition of the steel, it can also be used for hot mold steel, then H2367 and so on.

Plastic mold steel imported from Germany has the advantages of good wear resistance, high toughness, high hardness, high compressive strength and dimensional stability, and has good corrosion resistance, polishing and cutting performance is also very good, it is easy to achieve the mirror effect, and the hardenability and machining performance of injection mold steel are also very excellent, and it can also be hardened by air cooling. Die steel is also said to have superior performance, and only 6F7 die steel in the United States can be completely replaced.

It refers to the German Grietz mold steel, a plastic mold steel material.

Basic information: Chinese name material origin Germany Glitz steel mill material properties plastic mold steel material name Germany Glitz mold steel.

Material name: German Grieze die steel.

Material properties: plastic mold steel material.

Factory condition. Annealing hardness up to 285HB

Main characteristics: the steel has good wear resistance, high toughness, high hardness, high compressive strength, excellent dimensional stability, excellent corrosion resistance, good polishing and cutting performance, and easy to achieve mirror effect. Excellent hardenability, air-cooled hardening, excellent machinability.

Main application: a heavy-duty and high-toughness impression impression.

First, high-stress injection molds are required.

A heavy-duty cold work tool.

Everything sharpens tools.

First, a plastic mold with high hardness and high toughness is required.

Machining and polishing. Under normal conditions (without potions), the brightness of this steel can reach 90%.

The polishing process is as follows:

1.Polishing the surface with stone strips (from coarse to fine) as follows:

2.Sandpaper (coarse to fine) sand the surface as follows:

3.Polished directly with 1 diamond paste.

The above processes have basically reached the mirror effect after all the above processes have been done, if you find that some part of the effect is not ideal, you can redo it once according to the above process, and the problem will be solved.

Note: Sanding sandpaper needs to be repeated twice with the cross method.

Due to the high cleanliness of the steel and the homogeneity of the material, the polishing performance is superior and can achieve a high degree of mirror finishing.

Note: The pressure should not be too much when applying during polishing, so as not to cause surface defects.

German steel grades and their two corresponding standards: DIN EN ISO 4957-2001

The German steel grade corresponds to the national standard material 4Cr14Ni14W2Mo, which is similar to it.

The German steel grade, corresponding to the national standard material CR12, should be similar.

FYI.

The two grades you mentioned belong to one of the German standards for steel, "W-NR".
