They have a low to high carbon content, and contain 12% to 15% chromium and up to 1% molybdenum. It's used whenever corrosion resistance and-or oxidation 

The influence of pack, paste, and gas carburizing media upon the structure of the carburized layer on hypo- and hypereutectoid high-chromium (0.3 and 0.8 wt% C, 3-17 wt% Cr) steels was examined. The optimum case structure is produced by a pack mixture containing 2 wt% γ-Fe 2 O 3 ; the case is practically disposed of an oxidized zone and

The 9Cr-1Mo material is prevalent for burning nozzles in power plants and other high-temperature applications because of its creep resistance —its ability to maintain tensile strength at elevated temperatures. The 9Cr-1Mo with V, Nb (Cb), and N is even more resistant to creep and high-temperature hydrogen attack.

Cold-work tool steels which include D2, D3, D4, D5, and D7 steels are high-carbon, high-chromium steels. Apart from D3 steel all group D steels have 1% Mo and are air hardened. Type D3 steel is oil-quenched; though small sections can be

Figure 1At least a dozen chromium molybdenum (CrMo) steel combinations exist. One of the more recent alloys consists of chromium, molybdenum 

The percentage of chromium used in chromium steels varies over quite a wide range in the low-chromium and high-chromium steels. Tungsten steel is largely employed for high-speed metal cutting tools and magnet steels. It has also been used in the manufacture of armor plate and armor-piercing projectiles, in which case it is combined either with

D2 steel’s high chromium content gives it mild corrosion resisting properties in the hardened condition.Cold-work tool steels include the high-carbon, high-chromium steels or group D

The main shortcomings of actual 9-12Cr high-chromium steels are that the creep resistance is not enough to fulfill the engineering requirements at temperatures higher than 600°C and the material undergoes a cyclic softening. Creep strength at high temperature could be improved by a microstructural optimization through nano-precipitation

High carbon steel is often used for high-end kitchen knives because it is Stainless steel contains iron, carbon, and at least 10.5% chromium content.

2020. 7. 16. · Figure 1 shows the hardness curves measured on a cross-section for steels with low and high chromium contents. Measured hardnesses prior to nitriding were 540 HV for low alloyed steels 30Ni2CrMoV and 30CrMnSi, 300 HV for corrosion-resistant steel 03Cr11Ni10Mo2Ti, and 650 HV for tool steel Cr12Mo. After nitriding, the surface hardness of

The high strength and corrosion resistant properties of “stainless” steel containing more than five percent chromium were discovered in the early 1900s. Chromium steel resists warping and

Ways to increase the abrasive wear resistance of high-chromium steel depending on changes in the temperature of heating for quenching and cold treatment are
