What material is S136?
S136 is ASSAB's pre-hardened mirror acid-proof plastic mould steel, which is hardened with an electric furnace and full protective atmosphere, and has excellent corrosion resistance and polishability, as well as good toughness and ductility. In terms of machining, S136 has excellent machinability and abrasiveness, making it suitable for highly demanding mirror polishing processes. The factory hardness of S136 is HB210 240, and after hardening, the hardness can reach HRC50 55. In addition, S136 steel** is relatively high and is widely used in many industries due to its excellent properties, especially in the mold industry where high precision and high surface quality are required.
S136 corresponds to the Chinese grade.
In China, the corresponding grade of S136 is 3Cr2Mo steel. This grade has high strength and toughness, as well as good wear and corrosion resistance, and is suitable for the manufacture of plastic mold steels that require high strength and corrosion resistance. The hardness of 3Cr2Mo steel ranges between HRC30 40 and can be adjusted by heat treatment. Compared with S136, the ** of 3Cr2Mo steel is relatively low, but the overall performance is slightly inferior to S136.
Difference between S136 and S136H.
S136H is an improved version of S136, the main difference is the heat treatment process and the adjustment of the alloy composition. S136H adopts more precise temperature control and longer insulation treatment during the hardening process, which makes the internal structure of the steel more homogeneous, reducing microscopic defects and internal stresses. This results in improved corrosion resistance, toughness and durability of the S136H. At the same time, the alloy composition of S136H has also been optimized to improve the purity and uniformity of the steel, and further improve its mechanical properties and polishing properties. Therefore, the ** of S136H is also relatively high.
How many degrees of hardness is S136.
The hardness of S136 depends on its heat treatment process. In factory condition, S136 has a hardness of HB210 240, which is equivalent to HRC48 52. After hardening, its hardness can reach HRC50 55. It should be noted that the specific value of hardness will be affected by a variety of factors such as the chemical composition of the steel, the quality of smelting, the rolling process and the heat treatment process.
S136H material hardness.
The hardness of S136H depends on its heat treatment process. After hardening, the hardness of S136H can reach HRC50 55. Compared with S136, S136H has more stable hardness and mechanical properties, while having better corrosion resistance and polishing. This is mainly due to more precise temperature control and longer holding treatments, as well as an optimized alloy composition.
How much is a kilogram of s136 die steel.
Since S136 is a high-grade pre-hardened plastic mold steel, its ** is relatively high. The specific ** will be affected by various factors such as the quality, specifications, manufacturers, and market demand of the steel. In the Chinese market, the ** of S136 is usually around a few tens of yuan a kilogram, while the ** of imported brands may be higher. However, for situations that require large purchases, it is possible to get a better deal** by purchasing in bulk.
S136 steel**.
According to different specifications and grades, the ** of S136 steel is different. In the Chinese market, ASSAB's original S136 steel** is relatively high, while its domestic counterparts such as 3Cr2Mo steel** are relatively low. At the same time, the quality of steel will also be affected by various factors such as market supply and demand, production costs, etc. For users who need to buy S136 steel, they can choose the right quality and ** according to their actual needs.
S136 heat treatment hardness.
After heat treatment, the hardness of S136 depends on the treatment process and temperature control. Normally, after quenching and tempering treatment, the hardness of S136 can reach HRC50 55. In addition, surface hardness and wear resistance can be further improved through surface treatment technologies such as nitriding and hard chrome plating. It should be noted that the heat treatment process has a great impact on the performance and quality of S136, so it is very important to choose the right heat treatment process and parameters.
