What is the material of SA106B, and what material does this material correspond to in China SAE1006

SA106B is steel for boiler steel pipes, SA106B is an American brand, and China calls it 20G steel pipes.

20g steel pipe is mainly used in the manufacture of high-pressure and higher-parameter boiler pipe fittings, low-temperature section superheater, reheater, economizer.

and water-cooled walls, etc.; For example, small-diameter pipes are made of wall temperature 500 heating surface pipes, as well as water-cooled wall pipes, economizer pipes, etc., large-diameter pipes are made of wall temperature 450 steam pipes, headers (economizers, water-cooled walls, low-temperature superheaters and reheater joint boxes), medium temperature 450 pipeline accessories, etc.

It is a type of steel. SA-106B chemical composition.

<> SA106B seamless steel tube is mainly used for the heating surface tube of low and medium pressure boilers (the working pressure is generally not greater than that, and the working temperature is below 450); It is used for heating surface pipes, economizers, superheaters, reheaters, and pipes for the petrochemical industry in high-pressure boilers (the working pressure is generally above and the working temperature is between 450 and 650).

Hello dear! What material does SAE1006 correspond to in ChinaSAE1006 corresponds to in China. Mild steel is carbon steel with lower carbon content, which is also known as mild steel because of its low strength, low hardness and softness.

It includes most of the ordinary carbon structural steel and some high-quality carbon structural steel, most of which are used for engineering structural parts without heat treatment, and some are used for mechanical parts that require wear resistance after carburizing and other heat treatments. The annealed structure of mild steel is ferrite and a small amount of pearlite, which has low strength and hardness, and good plasticity and toughness. Therefore, its cold formability is good, and it can be cold formed by crimping, bending, stamping and other methods.

This steel also has good weldability. You can follow my steps to try it, and if you have any questions, you can give me feedback in time!

This material is the American standard: SAE J1868 - 2010 Restricted Hardenability Bands for Selected Alloy Steels The alloy steel number in the standard, the specific chemical composition is shown in the figure below

SAE 15B21 RH Chemical Composition Sheet.

It is a type of hardened alloy structural steel, and it is recommended that you consult the original standard.

Hello, it is a pleasure to serve you and give you the following answer: SA106M is an American standard carbon steel pipe, which is equivalent to 20 carbon steel pipe in China. Causes of the problem:

1.Due to the improper heat treatment process of SA106M carbon steel pipe, the thickness of the pipe wall is uneven, which affects the service life of the pipe. 2.

Due to the improper welding process of SA106M carbon steel pipe, the strength of the weld is insufficient, and the service life of the pipeline is affected. Workaround:1

In the heat treatment process, a reasonable heat treatment process should be adopted to ensure the uniformity of the sharpness of the pipe wall thickness, so as to improve the service life of the pipe. 2.In the welding process, a reasonable welding process should be adopted to ensure the strength of the weld to improve the service life of the pipeline.

Steps:1Heat Treatment:

First of all, the SA106M carbon steel pipe is put into the heat treatment furnace, and the heat treatment is carried out according to the specified temperature and time to ensure the uniformity of the thickness of the pipe wall. 2.Welding:

Then, the SA106M carbon steel pipe is put into the welding machine and welded according to the specified welding process to ensure the strength of the weld. Personal tip: When using SA106M carbon steel pipe, you should pay attention to the heat treatment and welding process to ensure the service life of the pipe.

SAE1010 is a standard of the Society of Automotive Engineers of the United States, the former "10" means that the MN content is about 1%, and the last "10" means that the average carbon content is; This material is close to the national standard low-carbon steel No. 10 steel, but the performance is better than that of No. 10 steel.

Characteristics: 1010 steel is a high-quality carbon structure shirt steel, low mechanical strength, good plasticity, toughness, easy to mold in the cold state, easy to cut processing, good welding performance, carburizing and cyanide treatment can be carried out to improve the surface hardness. It is used to manufacture welded parts, cold stamping parts, forgings and carburizing parts such as bolts, washers, partitions, shells, etc., which are not of high strength.

SAE1010 is a carbon structural steel.

1010 steel is a high-quality carbon structural steel, low mechanical strength, good plasticity, toughness, easy to mold in cold state, easy to cut, good welding performance, carburizing and cyanide treatment can be carried out to improve the surface hardness.

The previous "10" indicates that the mn content is about 1%, and the latter "10" indicates that the average carbon content is.
