34CrNiMo6因其優(yōu)良的綜合力學性能,廣泛用于制造發(fā)動機的凸輪軸及連桿等重要零件,加工性較差,屬于典型的難加工材料.

②表面硬化結構鋼用以制造表層堅硬耐磨而心部柔韌的零部件,如齒輪、軸等。為使零件心部韌性高,鋼中含碳量應低，一般在0.12～0.25%，同時還有適量的合金元素，以保證適宜的淬透性。氮化鋼還需加入易形成氮化物的合金元素（如al、cr、mo等）。滲碳或碳氮共滲鋼，經850～950℃滲碳或碳氮共滲后，淬火并在低溫回火(約200℃)狀態(tài)下使用。氮化鋼經氮化處理(480～580℃)，直接使用，不再經淬火與回火處理。

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.東北特鋼、寶鋼、興澄特鋼、長城特鋼、重特、大冶、進口34CrNiMo6代理商批發(fā)商報價格，冷拉光亮34CrNiMo6銀亮材光圓。哪個鋼廠有生產34CrNiMo6圓鋼材料？出廠價34CrNiMo6生產廠家。國產/進口34CrNiMo6價格是多少？特鋼/合金鋼34CrNiMo6化學成分、力學性能。
