產(chǎn)品詳情

12CrNi3鋼屬于合金滲碳鋼,比12CrNi2A鋼有更高的淬透性,因此,可以用于制造比12CrNi2A鋼截面稍大的零件。該鋼淬火低溫回火或高溫回火后都具有良好的綜合力學(xué)性能,鋼的低溫韌性好,缺口敏感性小,切削加工性能良好,當(dāng)硬度為HB260~320時(shí),相對(duì)切削加工性為60%~70另外,鋼退火后硬度低、塑性好,因此,既可以采用切削加工方法制造模具,也可以采用冷擠壓成型方法制造模具。為提高模具型腔的耐磨性,模具成型后需要進(jìn)行滲碳處理,然后再進(jìn)行淬火和低溫回火,從而保證模具表面具有高硬度、高耐磨性而心部具有很好的韌性,該鋼適宜制造大、中型塑料模具。但該鋼有回火脆性傾向和形成白點(diǎn)的傾向。

特性及適用范圍
是用途較廣的高級(jí)滲碳鋼,與15Cr、20Cr鋼相比,其強(qiáng)度、塑性、淬透性均高。主要用來制作重負(fù)荷條件下要求高強(qiáng)度,高硬度和高韌性的主軸及要求中心韌性很高或承受沖擊負(fù)荷、表面耐磨、熱處理變形小的軸、桿以及在高速和沖擊負(fù)荷下工作的各種傳動(dòng)齒輪、調(diào)節(jié)螺釘、凸輪軸

12CrNi3 steel is alloyed with carbon steel, which has a higher quenching property than 12CrNi2A steel. Therefore, it can be used to manufacture parts that are slightly larger than the 12CrNi2A steel. The hardened steel tempered at low temperature or high temperature tempering after has good comprehensive mechanical properties and good low temperature toughness of the steel, the small notch sensitivity, good cutting properties. When the hardness is HB260 to 320, relative machinability is 60% ~ 70 also low hardness of steel after annealing, good plasticity. Thus, the utility model can by cutting machining method to manufacture the mold, can also be used in cold extrusion molding method for manufacturing mold. In order to improve the wear resistance of the mold cavity, the mold needs for carburization, and then quenched and tempered at low temperature, so as to ensure the mold surface with high hardness, high wear resistance and heart department has a very good toughness, the steel suitable large and medium-sized plastic mold manufacturing. But the steel temper brittleness tendency and the formation of white spots.
Characteristic and applicable scope
It is widely used in high - carbon steel, compared with 15Cr and 20Cr steel, the strength, plasticity and quenching of the high - carbon steel are high. Mainly used to produce high strength requirements under the condition of heavy load, high hardness and high toughness of spindle and center toughness is high or under impact load, surface abrasion resistance, heat treatment deformation small shaft, rod and under high speed and impact load of various transmission gear, adjusting screw, a cam shaft
