特性 有較強(qiáng)的耐硝酸及有機(jī)酸的腐蝕。 用途 用作較高硬度及高耐磨性的熱油泵、閥片、閥門軸承、醫(yī)療器械、彈簧等零件。化學(xué)成份 碳 C ：0.36～0.45 硅 Si：≤0.60 錳 Mn：≤0.80 硫 S ：≤0.030 磷 P ：≤0.035 鉻 Cr：12.00～14.00 鎳 Ni：允許含有≤0.60力學(xué)性能 硬度 ：退火,,≤201HB,壓痕直徑3.9～4.3mm;淬火,≥50HV 熱處理規(guī)范及金相組織： 熱處理規(guī)范：1)退火,800～900℃緩冷或約750℃快冷;2)淬火,1050～1100℃油冷 ;3)回火,200～300℃快冷。 金相組織：組織特征為馬氏體型。交貨狀態(tài) 鋼材以退火狀態(tài)交貨。鍛造：油淬冷作模具鋼有一些裂紋敏感性，鍛造加熱時(shí)不宜迅速加熱，最好在650-750度進(jìn)行一次預(yù)熱，鍛造加熱溫度為1130-1150度，終鍛溫度應(yīng)大于800-850度，鋼錠鍛造時(shí)取上限溫度。坯料鍛造時(shí)取下限溫度 退火 一般退火采用780-800度，保溫4-6小時(shí)，以≤50度/小時(shí)，冷卻到550度出爐空冷，等溫退火采用700-800度保溫2-4銷售，然后再670-720度保溫，保持2-4小時(shí)，以≤50度/小時(shí)冷速冷卻到500度出爐空冷，退火硬度為241-197HB熱處理： 該鋼抗氧化性好，可在600~650℃長期使用。 表4-17-8 4Cr13鋼的熱處理 項(xiàng)目 退火 淬火 回火 加熱溫度/℃ 冷卻 750~800 爐冷 1050~1100 油冷 200~300 空冷
