40Cr Alloy Steel
40Cr alloy steel delivers high strength, wear resistance, and impact toughness—ideal for heavy-duty gears, shafts, and structural parts requiring durability and precision.

Detail
Product Description:
40Cr alloy steel is a medium carbon chromium steel widely used for its excellent strength, toughness, and hardenability. It performs well after quenching and tempering, achieving high mechanical strength and good fatigue resistance. With stable processing performance and uniform microstructure, 40Cr is ideal for manufacturing high-load, wear-resistant mechanical parts.
This material offers good machinability and dimensional stability, with minimal deformation during heat treatment. It is commonly applied in the production of gears, shafts, axles, bolts, spindles, and other transmission components. In automotive, construction machinery, and heavy equipment manufacturing, 40Cr is favored for its balance between toughness and wear resistance.
After proper quenching and tempering, the surface hardness of 40Cr alloy steel can reach 55–60HRC. It also exhibits high fatigue strength and impact resistance, ensuring long service life under cyclic or heavy loads. With optional surface treatments like nitriding or induction hardening, its wear and corrosion resistance can be further improved for demanding working environments.

Application description:
Due to properties such as high strength and corrosion resistance, alloy steel is widely used in four core fields, as detailed below:
1. Industrial Manufacturing
Mechanical Components: Quenched and tempered steels such as 40Cr, featuring impact resistance and heavy load resistance (e.g., gears, shafts).
Mold & Tooling: Cold-work die steel like Cr12 and hot-work die steel like H13, with high temperature resistance and wear resistance.
Bearings: High-carbon chromium steel such as GCr15, offering high hardness and fatigue resistance.
2. Energy & Chemical Industry
Oil & Gas Sector: 316L stainless steel and nickel-based alloys like Inconel 625, with acid-alkali resistance and high pressure resistance.
Power Sector: 12Cr1MoVG heat-resistant steel (for thermal power) and SA508 low-alloy steel (for nuclear power), providing high temperature resistance and radiation resistance.
Chemical Equipment: 2205 duplex steel and Hastelloy, enabling strong corrosion resistance (e.g., reaction kettles).
3. Transportation
Automotive: Q&P high-strength steel (for car bodies) and 45MnB alloy steel (for crankshafts), realizing lightweight and impact resistance.
Rail Transit: Q450NQR1 weathering steel (for carriage bodies) and CL60 bainitic steel (for axles), with corrosion resistance and wear resistance.
Aerospace: 300M ultra-high strength steel (for landing gears) and GH4169 superalloy (for engine blades), resisting extreme stress.
4. Military & Special Scenarios
Weaponry: Homogeneous armor steel (for tanks) and D6AC high-strength steel (for artillery shells), with armor-piercing resistance and explosion resistance.
Extreme Environments: 9Ni low-temperature steel (for polar equipment) and TC4 titanium alloy (for deep-sea detectors), offering low-temperature resistance and seawater corrosion resistance.
