根據(jù)冷作模具鋼的性能要求及形狀尺寸，材料的選用有以下幾種情況，只有充分進(jìn)行了解，才能使用的更好。
According to the performance requirements and shape and size of cold work die steel, the selection of materials has the following conditions. Only by fully understanding, can it be used better.
冷作模具鋼的選材
Material selection of cold working die steel
1、工作時(shí)受力不大、形狀簡(jiǎn)單、尺寸較小的模具，可用碳素工具鋼制造。
1. The die with small stress, simple shape and small size can be made of carbon tool steel.
2、工作時(shí)受力一般、形狀復(fù)雜或尺寸較大的模具，可用低合金工具鋼（如9Mn2V、9SiCr、9CrWMl3、CrWMn、Cr2等）制造。
2. Molds with general stress, complex shape or large size can be made of low alloy tool steel (such as 9mn2v, 9SiCr, 9crwml3, CrWMn, CR2, etc.).
3、工作時(shí)受力大，要求高耐磨性、高淬透性、變形量小、形狀復(fù)雜的模具，多用高碳高鉻鋼（Crl2、Crl2MoV等）制造。又發(fā)展了幾種Crl2型鋼的代用鋼（如Cr6WV、Cr4W2MoV、Cr2Mn2SiWMoV等），另外，也可選用高速鋼、低碳高速鋼（6W6M05Cr4V等）和基體鋼（化學(xué)成分相當(dāng)于高速鋼正常淬火后的基體成分的鋼）來制造這類模具。
3. The molds with large stress, high wear resistance, high hardenability, small deformation and complex shape are usually made of high carbon and high chromium steel (Crl2, Crl2MoV, etc.). Several alternative steels for Crl2 type steels have been developed (such as cr6wv, Cr4W2MoV, cr2mn2siwmov, etc.). In addition, high-speed steel, low-carbon high-speed steel (6w6m05cr4v, etc.) and matrix steel (steel with chemical composition equivalent to the matrix composition after normal quenching of high-speed steel) can also be used to manufacture such dies.
4、在沖擊條件工作，刃口單薄的模具，采用韌性較好的中碳合金工具鋼（如4CrW2Si、6CrW2Si等）制造。
4. The die with thin edge working under impact condition is made of medium carbon alloy tool steel with good toughness (such as 4crw2si, 6CrW2Si, etc.).
選用方法：
Selection method:
冷作模具鋼選用時(shí)需考慮加工方法、應(yīng)力狀態(tài)、成形加工對(duì)象的材料性質(zhì)、生產(chǎn)數(shù)量、板材厚度等，此外模具的大小及尺寸精度也是不可忽略的因素。
When selecting cold work die steel, the processing method, stress state, material property of forming and processing object, production quantity, plate thickness, etc. shall be considered. In addition, the size and dimensional accuracy of the die are also non negligible factors.
負(fù)荷較小或小批量生產(chǎn)時(shí)使用低合金工具鋼（SKS），負(fù)荷較大或大批量生產(chǎn)時(shí)使用冷作模具鋼（SKD），負(fù)荷更大時(shí)選用高速工具鋼及粉末高速工具鋼。
Low alloy tool steel (sks) is used for low load or small batch production, cold working die steel (SKD) is used for high load or large batch production, and high-speed tool steel and powder high-speed tool steel are used for higher load.
適用于耐磨場(chǎng)合的有冷作模具鋼、高速工具鋼及高合金高速工具鋼，適用于耐沖擊場(chǎng)合的有8Cr-2Mo系模具鋼和基體型高速工具鋼。
Cold working die steel, high-speed tool steel and high alloy high-speed tool steel are suitable for wear-resistant occasions, and 8cr-2mo series die steel and base type high-speed tool steel are suitable for impact resistant occasions.
