Vacuum Carbon Chromium Iron (GB/T5684-1987)
Vacuum carbon chromium iron, also known as high-strength low-alloy steel (HSLA), is a grade of steel alloyed with chromium and carbon for strength, toughness, and corrosion resistance. It is more commonly used in the consumer and industrial markets for automotive, construction and agricultural applications, due to its superior strength, corrosion resistance, and impact strength. Its use has extended to areas of metalworking and metallurgy, such as tool steels and cutting tools, as well as rings and cylinders used in hydraulic cylinders, pumps, and valves.
Vacuum carbon chromium iron is a special type of HSLA steel which may be used as a substitute for other grades, such as stainless steel or other grades of carbon steel. It has superior strength characteristics and may be used in place of a carbon steel or stainless steel when a higher strength is needed. This grade is often used in applications where the mechanical properties are critical, such as automotive components, lifting tools and fasteners. The use of chromium can also provide superior corrosion resistance, especially when compared to stainless steel.
Due to its superior properties, vacuum carbon chromium iron can be used for a number of different components with a variety of uses. It is most often used in components that require strength and durability in harsh environments, such as cylinders, shafts, and housings used in powerful engines, such as those found in automotive, heavy industrial, and agricultural applications. As a result, it is often utilized in off-road vehicles, such as ATVs, motorcycles and all-terrain vehicles.
Vacuum carbon chromium iron has the strength of more than other alloyed grades of steel and is typically used in applications that require abrasion resistance, good fatigue strength, and strength under heat. It is also highly resistant to abrasion, scuffing, denting, and compacting. These properties make vacuum carbon chromium iron ideal for applications requiring high accuracy of measurement and dimensional stability.
When compared to other HSLA steel alloys, vacuum carbon chromium iron has an improved machinability, as compared to other alloys. This grade typically softens more easily when it is machined instead of becoming harder and more resistant. It also has a higher resistance to cracking and work hardening, which provides users with the confidence that their parts will be stronger and hold up better in demanding applications.
In short, vacuum carbon chromium iron offers numerous advantages, especially in applications requiring mechanical properties, such as strength and ductility, toughness, and wear resistance. This grade of steel alloy is the perfect solution for a variety of applications that require strength, toughness, corrosion resistance, or machinability.
