● 產(chǎn)品名稱:
Cr12MoV合金工具鋼
● 國際通稱:
Cr12MoV、T21201
● 執(zhí)行標準:
GB/T1299等
● 主要成分(%):
碳(C)1.45~1.75
硅(Si)≤0.40
錳(Mn)≤0.40
磷(P)≤0.030
硫(S)≤0.030
鉻(Cr)11.00~12.50
鉬(Mo)0.40~0.60
釩(V)0.15~0.30
鈷(Co)≤1.00
● 物理/力學性能及熱處理工藝規(guī)范:
硬度:退火207-255HB,壓痕直徑3.8-4.2mm;試樣淬火≥58HRC。
普通淬火、回火規(guī)范:淬火溫度1000-1050℃,淬油或淬氣,硬度≥60HRC;回火溫度160-180℃,回火時間2h,或回火溫度325-375℃,回火次數(shù)2-3次。
冷擠壓摸毛坯軟化規(guī)范:使用生鐵屑保護加熱,溫度760-780℃,時間10h,爐冷,硬度196HBW,可順利實現(xiàn)冷擠壓成形。
普通等溫球化退火規(guī)范:850-870℃×3-4h,隨爐冷卻到740-760℃×4-5h等溫,出爐空冷,硬度≤241HBW,共晶碳化物等級≤3級。最佳等溫溫度740-760℃,時間≥4-5h。
球化退火規(guī)范:(860±10)℃×2-4h,以30℃/h冷速爐冷,(740±10)℃x4-6h,隨爐緩慢冷卻到500-600℃,出爐空冷,硬度207-255HBW。
● 特性及應用:
Cr12MoV工具鋼是碳鉬萊體鋼,其碳含量比Cr12工具鋼低很多,且加了鉬、釩元素,使鋼的熱加工性能、沖擊韌度和碳化物分布都得到了明顯改善。該鋼具有較好的耐磨性、淬透性、淬硬性、強韌性、熱穩(wěn)定性、抗壓強度以及微變形,綜合性能優(yōu)良和廣泛的適應性。受熱軟化溫度為520℃。截尺在4mm以下可以完全淬透,該鋼的耐磨性是低合金工具鋼3-4倍,淬體積變形。淬硬深度:油淬200-300mm。
Cr12MoV工具鋼宜用于制造各種高精度、長壽命的冷作模具、刃具和量具,例如:形狀復雜的沖孔凹模、切邊模、冷擠壓模、滾絲輪、搓絲輪、冷剪切刀和精密量具等。
