Auto parts and parts processing is the product that constitutes the whole of auto parts processing. With the increasingly fierce competition in the auto parts processing market, the concept of environmental protection is deeply rooted in people's minds, and the technology is constantly upgraded and applied: brake parts, drive train parts, engine parts, steering parts, etc. in auto parts.

Auto parts and parts processing is the product that constitutes the whole of auto parts processing. With the increasingly fierce competition in the auto parts processing market, the concept of environmental protection is deeply rooted in people's minds, and the technology is constantly upgraded and applied: brake parts, drive train parts, engine parts, steering parts, etc. in auto parts. The QL-HW2000B high-frequency infrared carbon-sulfur analyzer produced by Nanjing Kirin Analytical Instrument can be used with high-frequency induction furnace to quickly and accurately determine the content of various materials in automotive parts: carbon steel and alloy steel. This product is the crystallization of international and domestic advanced technology integration. It is a high-tech product integrating light, machine, electricity, computer and analytical technology. Many technologies are leading domestically.

Types of Metal Materials Commonly Used in Automobiles 1. Steel is an iron-carbon alloy with a carbon content of less than 2.1%. It is the most widely used metal material. Most of the important parts of the car are made of steel. There are many types of steel. According to whether there are other elements other than carbon, it can be divided into two categories: carbon steel and alloy steel. According to the carbon content, it can be divided into three categories: low carbon steel (C0.6%).

Infrared carbon and sulfur analyzer can detect various steel elements in auto parts

A steel in which carbon steel does not have other elements other than carbon for improving performance is called carbon steel. The mechanical properties of carbon steel can meet the requirements of structural parts and mechanical parts of many equipments, meet the requirements of some tool steels, have excellent processability and low price, and are widely used in the automotive industry and other industries. .

Alloy steel adds one or more appropriate alloying elements to carbon steel to improve certain properties of steel, called alloy steel. The alloying elements often added to carbon steel are Si, Mn, Cr, Ni, W, V, Mo, Ti, and the like. Alloy steel is divided into alloy structural steel, alloy tool steel and special performance steel according to the application.

3 major categories. Alloy structural steels have high strength and good toughness and are mainly used in automobiles to manufacture parts that are subject to heat, wear and impact loads.

The grade of the alloy structural steel is indicated by “two digits + element symbol + number”: the first two digits indicate that the carbon content in the steel is a few ten thousandth; the element symbol indicates the alloying element contained; the latter number indicates the average content of the alloying element. percentage.

(2) Use alloy structural steel 40Cr, often used as important tempering parts, such as valves, cylinder head bolts, wheel bolts, half shafts and important gears; 18CrMnTi, commonly used to manufacture transmission gears, main drive bevel gears, etc.; 40MnB, 40Cr steel is used as knuckle, half shaft, spline shaft, etc.; 60Si2Mn steel is used to manufacture leaf springs.

Second, cast iron has good castability, wear resistance and machinability. Parts with low mechanical properties, complex shapes, and difficult forging are often made of cast iron, such as cylinder block, cylinder liner, rear axle housing, flywheel, brake drum, etc. Cast iron is divided into white cast iron, gray cast iron, ductile iron, malleable cast iron and alloy cast iron.
