Cr12是一款高碳高鉻型萊氏體冷作模具鋼,硬度高,可達(dá)HRC60,但脆性大,模具*易開裂;淬透性差,心部無法淬硬,熱處理后變形量大。好處是便宜,其它性能跟DC53相比, 都是缺點(diǎn)。
Cr12 is a high carbon and high chromium ledeburite cold working die steel with high hardness up to HRC60, but it is brittle and the die * is easy to crack; The hardenability is poor, the core cannot be hardened, and the deformation is large after heat treatment. The advantage is that it is cheap. Compared with DC53, other performances are disadvantages.
DC53是一款抗崩裂性能好的冷作模具鋼,硬度HRC60-62,耐磨性好,抗崩裂性能是SKD11的2倍,模具不會(huì)開裂;且淬透性好,心部硬度和表面硬度趨于一致。
DC53 is a cold working die steel with good anti cracking performance, with hardness of hrc60-62 and good wear resistance. The anti cracking performance is twice that of SKD11, and the die will not crack; The hardenability is good, and the core hardness and surface hardness tend to be the same.
主要表現(xiàn)在:
It is mainly reflected in:
1)DC53的抗崩裂性能比Cr12強(qiáng)很多倍,DC53做的沖壓模具不易開裂,用Cr12做的沖壓模具,開裂是必然現(xiàn)象。
1) The anti cracking performance of DC53 is many times stronger than that of Cr12. The stamping die made of DC53 is not easy to crack. For the stamping die made of Cr12, cracking is an inevitable phenomenon.
2)使用硬度不同,Cr12硬度一般是GRC55-58,硬度高了容易開裂;DC53的正常硬度HRC60-62
2) The hardness of Cr12 is generally grc55-58, which is easy to crack when the hardness is high; Normal hardness of DC53 hrc60-62
3)線切割開裂風(fēng)險(xiǎn)不一樣,Cr12淬火加硬后,線切割要開裂,而DC53不會(huì)。
3) The risk of wire cutting cracking is different. After quenching and hardening of Cr12, wire cutting will crack, while DC53 will not.
4)淬硬性不同,Cr12心部無法淬硬,而DC53的表面硬度和心部硬度趨于一致。
4) With different hardenability, the core of Cr12 cannot be hardened, while the surface hardness and core hardness of DC53 tend to be the same.
5)使用場合不同,Cr12用于僅要求耐磨,沒有沖擊的模具工況,模具結(jié)構(gòu)簡單;DC53主要用于要求抗沖擊韌性的場合,且能保證很好的耐磨性。DC53主要用于模具制造。
5) Different application occasions, Cr12 is used for die working conditions requiring only wear resistance and no impact, and the die structure is simple; DC53 is mainly used in occasions requiring impact toughness, and can ensure good wear resistance. DC53 is mainly used for mold manufacturing.
6)售價(jià)不同,Cr12的好處是便宜,DC53售價(jià)比Cr12高好幾倍。
6) The price is different. The advantage of Cr12 is that it is cheap. The price of DC53 is several times higher than that of Cr12.


如果用一句話表達(dá)DC53和Cr12的區(qū)別,可以用新舊社會(huì)兩重天來形容也不為過。
If the difference between DC53 and Cr12 is expressed in one sentence, it can be described as the dual heaven of the old and new society.
有人問:LD模具鋼和DC53模具鋼哪個(gè)好?
Someone asked: which is better, LD die steel or DC53 die steel?
LD的冷鐓模具鋼,DC53是抗崩裂性能好的冷作模具鋼。他們的使用硬度都是HRC60-62,耐磨性相當(dāng),但DC53的抗崩裂性能比LD好。
LD cold heading die steel, DC53 is a cold working die steel with good cracking resistance. Their use hardness is hrc60-62, and the wear resistance is equivalent, but the cracking resistance of DC53 is better than that of LD.
表示抗崩裂性能的技術(shù)參數(shù)是沖擊功值,DC53硬度HRC61的沖擊功值是72焦耳,LD硬度HRC54的沖擊功值是18.4焦耳(沖擊功數(shù)值和式樣尺寸大小有關(guān),不是值),由此表明,LD的抗沖擊能力差于DC53。
The technical parameter indicating the anti cracking performance is the impact energy value, the impact energy value of DC53 hardness HRC61 is 72 joules, and the impact energy value of LD hardness hrc54 is 18.4 joules (the impact energy value is related to the size of the pattern, not the value), which shows that the impact resistance of LD is worse than that of DC53.
還有LD模具鋼的淬火溫度高達(dá)1100℃,DC53淬火溫度1020-1050℃;LD的熱處理工藝不好把控,熱處理出來的材料性能不穩(wěn)定;而DC53的熱處理工藝更加容易把控,這對(duì)工業(yè)生產(chǎn)有好處。
In addition, the quenching temperature of LD die steel is as high as 1100 ℃, and the quenching temperature of DC53 is 1020-1050 ℃; The heat treatment process of LD is not easy to control, and the properties of materials after heat treatment are unstable; The heat treatment process of DC53 is easier to control, which is beneficial to industrial production.
