Application of steel pipe in marine engineering
2022-02-17 11:02:26The application of steel pipes in marine engineering is very common. There are roughly three types of steel pipes in the two major systems of shipbuilding and marine engineering: conventional steel pipes, structural steel pipes and spec
Classification and process production method of galvanized steel sheet
Galvanized steel plate is to prevent the surface of the steel plate from being corroded and prolong its service life. The surface of the steel plate is coated with a layer of metal zinc.According to the production and processing methods, it can be divided
What are the advantages of seamless steel pipes?
Compared with many steels, seamless steel pipes have excellent characteristics. Compared with solid steels such as round steels, they are lighter in weight when the bending and torsional strength is the same. They are economical section steels and are wid
Introduction to spiral welded pipes
Spiral welded pipe is made by rolling low carbon carbon structural steel or low alloy structural steel strip at a certain helical angle (called forming angle) into a tube blank, and then welding the pipe seams.The advantages of spiral welded pipe:1. Steel
The differences between 12cr1mov steel and 15CrMo steel
Both 12cr1mov steel and 15CrMo steel are alloy structural steels. Due to different chemical compositions and various properties, the environmental conditions used are different. A detailed analysis is given below.1. Differences in chemical composition12cr
The treatment method of steel plate rust
As we all know, the steel plate is easy to rust after being placed for a long time, which not only affects the appearance, but also affects the price of the steel plate. So what should be done after the steel plate is rusted?1. Power tool rust removalPowe
How is high strength low alloy steel made
A high strength low alloy steel is a carbon steel that has a small amount of alloying elements added to its chemical composition.Alloying elements are mainly used to increase the strength of steel.High-strength low-alloy steel can provide higher strength
Grades and uses of high strength low alloy steels
There are many different grades of high strength low alloy steel. The intended uses of high strength low alloy steel depends primarily on chemical composition and grade application.ASTM A36 is one of the most popular high strength low alloy steel. It is a
What is 09CuPCrNi-A steel plate
09CuPCrNi-A steel plate is a high strength weather resistant steel plate. Among them, the combination of Cu and P can resist the corrosion of the atmosphere, and there are also Cr and Ni, which are all materials used in stainless steel. Weather resistant
What is S355J2 low alloy steel plate?
S355J2 low alloy steel plate has good comprehensive mechanical properties, low temperature impact toughness, cold stamping, machinability.
Classification of abrasion resistant steel plate
Abrasion resistant steel plate is widely used in machinery manufacturing, so what types of abrasion resistant steel plate are there?1. High manganese steelThe as-cast structure of high manganese steel is usually composed of austenite, carbide and pearlite
What are the differences between 42CrMo steel plate and 42CrMoA steel plate?
42CrMo steel plate and 42CrMoA steel plate both belong to the national standard high strength alloy structural steel.The implementation standard of 42CrMo steel plate is GB/T 3077-2015, and the implementation standard of 42CrMoA steel plate is GB/T 3077-1
The role of nickel, molybdenum and vanadium elements in steel
The role of nickel in steel1. It can improve the strength of steel without significantly reducing its plasticity;2. Improve the low temperature toughness of steel;3. Improve the workability and weldability of steel;4. Improve the corrosion resistance of s
Introduction of hot rolled steel plate and cold rolled steel plate
The mechanical properties of hot rolled steel plate are far inferior to those of cold working and forging, but they have better toughness and ductility.V Cold rolled steel plates have low toughness due to a certain degree of work hardening, but can achiev
Rust spot of weather resistant steel plate
The first stage: The weather resistant steel begins to grow small rust spots, the rust spots of ordinary steel plates are relatively loose, and some of the rust treatment is poor and even peels off the rust.The second stage: The weather resistant steel ha
