34CrNiMo6因其优良的综合力学性能,广泛用于制造发动机的凸轮轴及连杆等重要零件,加工性较差,属于典型的难加工材料.

②表面硬化结构钢用以制造表层坚硬耐磨而心部柔韧的零部件,如齿轮、轴等。为使零件心部韧性高,钢中含碳量应低，一般在0.12～0.25%，同时还有适量的合金元素，以保证适宜的淬透性。氮化钢还需加入易形成氮化物的合金元素（如al、cr、mo等）。渗碳或碳氮共渗钢，经850～950℃渗碳或碳氮共渗后，淬火并在低温回火(约200℃)状态下使用。氮化钢经氮化处理(480～580℃)，直接使用，不再经淬火与回火处理。

34CrNiMo6 because of its excellent mechanical properties, widely used in the manufacture of engine camshaft and connecting rod and other important parts, the machining is poor, which is typical of difficult processing materials.
Chemical composition
C carbon: 0.34
Si silicon: 0.25~0.30
Mn Mn: 0.5
Mo Mo: 0.2
Cr Cr: 1.5
Ni nickel: 1.55
34CrNiMo6 after quenching and tempering treatment, hardness of 36 ~ 40HRC, tensile strength, sigma B is 1 100 MPa, elongation was 12%, the impact toughness values of alpha kappa 8kg / cm2
Heat treatment:
34CrNiMo6 its quenching and tempering process for 850 degrees of 580 degrees of oil quenching tempering
Classification:
Quenched and tempered structural steel
Surface hardened steel
This kind of steel quenched and tempered [2] carbon content is generally about 0.25% ~ 0.55%, for established section size of structure parts, in quenching and tempering treatment (quenching and tempering), if along the cross section of the quenching through, good mechanical properties, if quenching impermeable, microstructure appears free ferrite, toughness decrease. The temper brittleness of the steel such as manganese steel, chrome steel, nickel chromium steel, tempering after rapid cooling. This kind of steel quenching critical diameter, with the increase of crystal size and the contents of alloy elements increases, for example, 40Cr steel and 35SiMn about for 30 ~ 40mm, and 40CrNiMo 30crni2mov steel about 60 ~ 100mm, commonly used in the manufacture of bear large loads of the shaft and the connecting rod structure.
The surface hardening structure steel is used to make the surface hard and wear resistant and the core of the heart is flexible, such as gears, shafts, etc.. In order to make the parts of the heart of the high toughness, steel, the carbon content should be low, generally in the 0.25% ~ 0.12, while the amount of alloying elements, to ensure the suitability of the quenching. Nitriding steel is also required to be added into the alloy elements (such as Al, Cr, Mo, etc.). Carburizing or carbon nitrogen co cementation steel, after 850 ~ 950 carburizing or carbon nitrogen, quenching and tempering at low temperature (about 200 c) state. Nitriding treatment (480 ~ 580), direct use, no longer after quenching and tempering treatment.东北特钢、宝钢、兴澄特钢、长城特钢、重特、大冶、进口34CrNiMo6代理商批发商报价格，冷拉光亮34CrNiMo6银亮材光圆。哪个钢厂有生产34CrNiMo6圆钢材料？出厂价34CrNiMo6生产厂家。国产/进口34CrNiMo6价格是多少？特钢/合金钢34CrNiMo6化学成分、力学性能。
