20CrNiMoHA quenching and tempering structural steel has good machining and forming characteristics, and is also resistant to heat. The heat treatment process used on the steel produces a combination of mechanical strength and fatigue strength which is ideal for heavy duty work applications and for components operating in highly corrosive environments. Due to its superior corrosion resistance, 20CrNiMoHA quenching and tempering structural steel is well suited for use in applications where corrosion resistance is essential, and it is also used in a variety of marine applications.

20CrNiMoHA quenching and tempering structural steel can withstand high temperatures and is easy to maintain. The surface of the steel is highly resistant to abrasion, which makes it suitable for use in areas where abrasive materials are commonly present. The toughness and ductility of the steel allow it to be shaped into complex parts, which makes it possible to produce intricate parts with complex shapes. It is ideal for applications that need to be made to exact dimensions.

In addition to its excellent mechanical properties, 20CrNiMoHA quenching and tempering structural steel is also highly resistant to corrosion. This makes it ideal for corrosive environments such as swimming pools, sea water, and other areas that require corrosion protection. Its resistance to corrosion also makes it suitable for use in components which are used in a range of industrial environments, such as food processing. The high degree of hardness makes the steel suitable for use in the manufacture of heavy-duty machinery and industrial parts, such as drills and valves.

20CrNiMoHA quenching and tempering structural steel provides excellent toughness and strength, as well as offering corrosion resistance. It is also highly resistant to wear and tear, making it suitable for applications requiring high levels of wear resistance and strength. Its ability to be machined and formed makes it an excellent choice for use in the manufacture of components and machinery. Its resistance to heat and its resistance to corrosion make it an ideal choice for heavy-duty machinery and industrial applications.

20CrNiMoHA is a kind of low-carbon, nickel-molybdenum alloy steel which is widely used for producing gears and components that need to be heat- treated or quenched. It is strong and can bear higher workloads and has good toughness. It is generally used in the manufacture of parts that require good strength and wear resistance, such as gears, shafts, bearings and other mechanical components.

20CrNiMoHA steel is widely used in automotive, agricultural, locomotive, military and other industries. Due to its high strength and good toughness, it is also widely used in the manufacturing of heavy-duty parts such as gears, shafts, axles, crankshafts and so on. This steel is also widely applied in the field of aviation and aerospace. The advantages of this steel include the high hardness, wear resistance, low deformation and good fatigue resistance. Furthermore, it has good resistance to corrosion and impact and most importantly, it has excellent quenching and tempering properties.

When it comes to heat treatment, 20CrNiMoHA steel should be heated at 930-950℃ first, to be deprived of its internal stress, then over-tempered at 710-730℃ for its quenching, then cooled in oil. After that, it should be heated again at 630-680℃, to be tempered. As a result, it will obtain better comprehensive mechanical properties and meet the requirement of toughness, strength and serve longevity.

Generally, the chemical composition of 20CrNiMoHA steel includes Carbon (C) 0.17-0.23; Manganese (Mn) 0.30-0.60; Silicon (Si) 0.17-0.37; Chromium (Cr) 0.80-1.10; Nickel (Ni) 0.40-1.00; Molybdenum (Mo) 0.90-1.20 and Phosphorus (P) ≤ 0.025; Sulphur (S) ≤ 0.025.

In conclusion, 20CrNiMoHA steel is the ideal choice in many industries due to its strength, toughness and quenching and tempering features. In order to ensure its optimal performance, it should be processed correctly and its heat treatment processes should be followed strictly.
