Summary: Chromium-molybdenum alloy steel (or chrome moly), is an alloy employed for high pressure and temperature ’s used in construction, oil and gas, energy, and the automotive industries because of its corrosion resistance and high-temperature and tensile strength.
The gear material is made of high-grade chromium-molybdenum-vanadium alloy steel, which is quenched and tempered to a substrate hardness of 30 rc, and then the advanced iron nitriding equipment is used to nitride the hardness of the gear surface to 840 hv to obtain the best wear resistance and impact toughness.

The gearbox and inner ring gears are designed in one piece, with compact structure, high precision and high output torque. Servo precision planetary reducer features: High rigidity, the gear adopts alloy steel nitriding hard tooth surface, which has superior wear resistance and impact resistance;
Description. 4130 is a low alloy steel containing molybdenum and chromium as strengthening agents. The carbon content is nominally % and with this relatively low carbon content the alloy is excellent from the fusion weldability standpoint.
72 gear teeth for 5 degree sweep. Chrome vanadium alloy steel for strength and durability. drill bits with titanium nitride finish.
Rails, therefore, of the carbon content in vogue when 80 lb. was a large section ( to per cent.) with per cent, chromium and per cent, molybdenum could be readily rolled and finished at the necessarily high temperature required for the 130-lb. section, producing a uniform fine grain and with an elastic limit in excess of the per cent, carbon steel now in use.
But since nitriding is a completely different chemical and metallurgical process, you can only nitride steel with alloying elements that will form stable nitride molecules, which means you need chromium, molybdenum, vanadium, or aluminum alloy, since those elements form stable nitrides when saturated with nitrogen.
Chromium-vanadium steel is an alloy made of iron with carbon, chrome and vanadium added to improve the properties of the metal. These alloys vary by percentage of additives; they commonly are stronger at high temperatures. Chrome-vanadium steel combines strength with flexibility.
High-strength low-alloy steel (HSLA) is a type of alloy steel that provides better mechanical properties or greater resistance to corrosion than carbon steels vary from other steels in that they are not made to meet a specific chemical composition but rather to specific mechanical properties.
High-speed steels, or HSS for short, are high-alloy tool steels with large amounts of alloying elements such as tungsten, molybdenum, chrome, and vanadium.
