Unique Properties of Custom 450 Round Bar for High-Stress Applications

Exceptional Strength:

Custom 450 round bar offers exceptional strength and hardness thanks to its high levels of nickel, molybdenum, and titanium, making it a popular choice for applications where strength is essential. As a result, it’s commonly used in aircraft parts, oil drill bits, and shafts and components for heavy industrial equipment. The strength and hardness of the custom 450 round bar also make it resistant to deformation, even under heavy loads. This feature is critical when it comes to high-stress applications, as it ensures the material can withstand pressure without failing.

Corrosion Resistance:

The custom 450-round bar is highly corrosion-resistant, making it an ideal material for challenging environments. This is due to its chromium and molybdenum content, which creates a protective barrier on the alloy’s surface, inhibiting corrosion and rust. The ability to resist corrosion makes the custom 450 round bar a common material in maritime and offshore applications and the chemical and petrochemical industries.

Custom 450 Round Bars offer an exceptional combination of corrosion resistance, wear resistance and strength. The alloy is martensitic stainless steel, with a high chromium content that provides superior corrosion resistance to chloride environments. Additionally, the presence of nickel gives it excellent formability and weldability. When tempered in the higher hardness levels (40-55 HRC), it offers a very high yield strength of up to 400 Mpa (58 ksi). These properties make Custom 450 an ideal choice for applications requiring corrosion and mechanical stress resistance.

Heat Resistance:

Custom 450-round bars can withstand significant temperature variations without losing their key properties. The custom 450 round bar is an excellent choice for high-stress applications due to its superior heat resistance. It’s heat-treatable and can sustain high-temperature environments without compromising its strength. This property is useful in applications where the material needs to retain its strength, even at high temperatures. For example, it’s often used in engines, turbines, and exhaust systems that are exposed to high heat stress.

It offers outstanding hardness at both elevated and sub-zero temperatures, allowing it to be used in harsher environments than other steel grades. Custom 450’s good corrosion and oxidation resistance also make it ideal for any application that may come into contact with moisture or humidity. This, in combination with its toughness, makes Custom 450 a great option for any project where durability and longevity are important factors.


Custom 450 round bar has uniformity in composition and microstructure, which makes it easy to machine and fabricate. It’s easy to drill, tap and weld and can be easily formed using conventional metalworking techniques. Its excellent machinability is a bonus in high-stress industrial applications, ensuring an easy and smooth fabrication process.

Wear and Tear Resistance:

Custom 450 round bar has excellent wear and tear resistance properties thanks to its high levels of molybdenum and titanium. This property is particularly useful in industrial applications that require components that can withstand harsh wear and be durable over time. Therefore, it’s commonly used in gears, pins, and other parts that undergo heavy wear in industrial machines.


The custom 450 round bar is a heavyweight contender in high-stress industrial applications. Its unique properties, such as exceptional strength, corrosion resistance, heat resistance, excellent machinability and wear and tear resistance, make it an ideal material choice for harsh environments. The material has a proven track record, making it popular in aerospace, oil and gas, and nuclear plants. If you’re in the market for materials that can withstand harsh environments and perform under intense pressure, a custom 450-round bar should be on your list of options. It’s versatility and reliable performance make it a go-to material for applications that require strength and durability.
