Have you ever paid attention to the various production and living items around you? They are made of various different materials. The tableware we use for meals is usually made of stainless steel or ceramic. When we go shopping in the supermarket, we use plastic packaging bags. And we also live in apartment buildings constructed of concrete and steel. Each material has its own characteristics:
In the machine precision processing industry, various types of steel have different applications.
the selection of materials is the decisive factor for product performance, service life, and cost control. The following are several common engineering materials, each with unique physical and chemical properties, widely used in different industrial scenarios.
Aluminum alloy is famous for its light weight, good thermal conductivity, and excellent processability. It has medium strength and outstanding corrosion resistance. Especially after anodic oxidation treatment, the surface hardness and aesthetics are greatly improved. 6061 and 7075 are two common grades. The former is easy to process and weld, widely used in frame structures; the latter has strength close to steel and is often used in aviation parts. Due to its low density, aluminum alloy is the preferred material for equipment lightweighting.
The core advantage of stainless steel lies in its excellent corrosion resistance, which is due to the addition of chromium in the material, which can form a dense oxide film on the surface. 304 and 316 are the most commonly used austenitic stainless steels. 316 has stronger resistance to chloride corrosion due to the addition of molybdenum, which is suitable for marine or chemical environments. Stainless steel is non-magnetic, sanitary, and durable. It is widely used in medical devices, food processing equipment, and high-end industrial parts. However, its work hardening phenomenon is obvious, which puts forward higher requirements for cutting technology.
Cast iron is a type of ferrocarbon alloy with high carbon content, which is widely used for its excellent casting performance, shock absorption, and low cost. Gray cast iron (such as HT250) has good cutting processability and is often used to manufacture structural parts such as machine tool beds and boxes that require stability. Ductile iron (such as QT400-18) has mechanical properties close to steel through spheroidization treatment, with both wear resistance and shock absorption. It is often used to manufacture parts that bear impact, such as crankshafts and gears.
Commonly known as "white steel" or carbon tool steel, this type of material has high hardness and good wear resistance, but poor red hardness (the ability to maintain hardness at high temperatures). It is often used to manufacture tools or measuring tools with simple shapes and low-speed cutting. In mold manufacturing, it is also often used as a material for parts that require hardness but have little impact. Due to its relatively low price, it is an ideal choice for many general tools.
Tungsten steel belongs to a type of cemented carbide, usually referring to an alloy material based on tungsten carbide with the addition of metals such as cobalt as a binder. It has extremely high hardness and wear resistance, as well as good compressive strength. It is often used to manufacture high-precision, long-life molds, tools, and wear-resistant parts. The hardness of tungsten steel is second only to diamond. It can handle hard materials that are difficult for ordinary steel to process. It is an indispensable "industrial teeth" in modern industry.
Cemented carbide, also known as tungsten titanium cobalt alloy, is a composite material made through powder metallurgy processes. It consists of refractory metal carbides (such as tungsten carbide, titanium carbide) and metal binders (such as cobalt, nickel). Cemented carbide shows extremely high hardness, wear resistance, and red hardness. It can maintain cutting performance even at high temperatures. Therefore, it is widely used in the manufacture of cutting tools such as turning tools, milling cutters, and drills, as well as extreme wear-resistant parts such as wire drawing dies and nozzles.
Carbon steel is the basic form of ferrocarbon alloy. According to the different carbon content, it can be divided into low carbon steel, medium carbon steel, and high carbon steel. Q235 is a typical low carbon steel with good plasticity and easy welding. It is often used to manufacture structural parts, supports, and bolts. 45 steel is the most widely used medium carbon steel. After quenching and tempering treatment, it has good comprehensive mechanical properties and is suitable for manufacturing moving parts such as shafts and gears. Carbon steel has low cost and good processability. It is the material with the largest usage in machinery manufacturing.
High speed steel is a type of tool steel with high hardness, high wear resistance, and high heat resistance. It can still maintain cutting hardness at a cutting temperature of up to 600°C, so it is especially suitable for manufacturing tools for high-speed cutting. M2 is a common high speed steel grade, widely used in the manufacture of drills, taps, milling cutters, etc. Compared with cemented carbide, high speed steel has better toughness and is not easy to collapse. It is suitable for manufacturing tools with complex shapes.
The pipe stand and brackets of Bohui are usually made of Q235B carbon steel. Using Q235B material offers significant advantages in terms of cost-effectiveness, processing performance, and structural reliability. It is particularly suitable for industrial support equipment that requires moderate strength and is suitable for mass production.
Bohui also manufacturer the pipe stand brackets under the customer’s requirement .Including the color,structurer ,and the raw material.
