What kind of steel is A138, what kind of steel is A106?

There are many types of steel, which can generally be classified into four categories: profile, plate, tube and wire. 1. There are many varieties of section steel, which is a kind of solid strip steel with a certain cross-sectional shape and size. According to the different cross-sectional shapes, it is divided into two types: simple and complex cross-sections.

The former includes round bars, square bars, flat bars, hexagonal bars and angle bars; The latter includes rails, I-beams, channel steels, window frame steels and special-shaped steels. The diameter of the small round steel is called the wire. 2. Steel plates are divided into three types: thin plate (thickness <4mn), medium plate (thickness 4-25mn) and thick plate (thickness 25mm) according to different thicknesses.

3. Steel pipe This is a kind of long steel with hollow section. According to its different cross-sectional shapes, it can be divided into round pipes, square pipes, hexagonal pipes and various special-shaped cross-section steel pipes. According to different processing technology, it can be divided into two categories: seamless steel pipe and welded steel pipe.

A138 is not a regular steel grade, not only in China, but also in major countries in the world There is no A138 sequence. This question often arises because the design unit or material supplier uses the factory number.

The purpose of using the factory code to replace the regular grade is to keep it confidential, so as to prevent competition with the enterprise, and the quality cannot be compared because there is no regular grade.

After the material has a problem, the supplier can take out its own appraisal report and say that its brand is genuine, because this report is also issued by himself, so it can effectively avoid the compensation problem caused by inferior materials.

You can tell the place and environment you use and the basic requirements, etc., so that it is easy to deduce what kind of material this material is.

You can also take it to a slightly more professional material manufacturer for discharge detection, which is the most accurate.

A106 is made of stainless steel.

A106-A is equivalent to 10 steel materials in China, and A106-B is equivalent to 20 materials in China, which is a more commonly used steel pipe material at home and abroad. A106 seamless steel pipe is mainly used in construction, machining, electrical, petrochemical and other industries.

There are two main production processes, one is cold drawing and the other is hot rolling, in which cold drawing has higher dimensional accuracy than hot rolling, and the surface of the hot-rolled steel pipe is relatively rough. Large-diameter seamless steel pipes are hot-rolled steel pipes, and small-diameter seamless steel pipes are cold-drawn. The exported A106 seamless steel pipe should be beveled, painted, and treated with plastic pipe caps at both ends, and it needs to go through commodity inspection, and it can only be exported after passing the commodity inspection.

The main export countries are Malaysia, the United States, Thailand, Saudi Arabia, Brazil, Italy, etc.

ASTM A106 Pressure Bearing Calculation for Seamless Steel Pipe

Select s=8;P is smaller than the seamless steel pipe, S is the safety factor seamless steel grinding pipe, and the wall thickness is 3mm.

The pressure that the tube can withstand is p=(2*s*δ)d.

Let the tensile strength of the material be , and Zhan Suirong learned that the outer diameter of the pipe was d.

Tube wall thickness δ=(p*d) (2*s).

where s is the safety factor.

Because p is less than 7MPa daily gold doujin, Zhan Yurong learned that S chooses s=4.

We choose a safety factor of s=6;The tensile strength of 20 steel is 410MPa steel market, and the outer diameter of the pipe is d.

A106 seamless steel pipe belongs to the American standard steel pipe, A106 includes A106-A, A106-B. The former is equivalent to 10 materials in China, and the latter is equivalent to 20 materials in China. It belongs to the ordinary carbon steel series and is one of the commonly used materials.

ASTM A106 seamless steel pipes include both cold-drawn and hot-rolled processes. In addition to the difference in production process, the two are different in terms of precision, surface quality, minimum size, mechanical properties, and organizational structure. It is widely used in petroleum, chemical industry, boiler, power station, shipbuilding, machinery manufacturing, automobile, aviation, aerospace, energy, geology, construction and military industry.

Summary. Hello and thank you for your question. As far as I know, steel A1064 is a high-strength steel bar, the main components of which are carbon, manganese, silicon, phosphorus and sulfur.

It is a kind of cold-drawn steel bar, which has high strength, high toughness and good weldability, and is widely used in construction, bridges, tunnels, water conservancy projects and other fields.

Good. Hello and thank you for your question. As far as I know, steel A1064 is a high-strength steel bar, the main components of which are carbon, manganese, silicon, phosphorus and sulfur.

It is a kind of cold-drawn steel bar, with high strength, high toughness and good early grip weldability, widely used in construction, bridges, tunnels, water and land Heqingli engineering and other fields.

I also learned that the steel A1064 has a strength grade of 100 ksi, which means that it has a tensile strength of 100,000 psi. It ranges from inches to inches in diameter and 20 feet to 80 feet in length. Steel A1064 also has good corrosion resistance, and can be used in harsh environments.

In short, steel A1064 is a kind of cold-drawn steel bar with high strength beam, high toughness and good weldability, its strength grade is 100 ksi, the diameter range is inches to inches, and the length range is 20 feet to 80 feet.

What material of steel is it equivalent to in China?

Dear, I will help you find out that it is equivalent to the domestic HRB400 level of steel bar material. <>

Alloy steel bolt material for high temperature, A193 is a standard code of American standard bolt material, B7 is the material grade;

It is equivalent to the domestic 42CRMO or 42CRMOA chromium-molybdenum alloy structural steel, which is suitable for alloy steel and stainless steel bolt materials on Pairang pressure vessels, valves, flanges and fittings used at high temperatures.

The chemical composition and mechanical properties of A193 GR B7 bolts should meet the requirements of the A193 GR B7 standard, and the chemical composition and mechanical properties of the A194 GR 2H nut should meet the requirements of the A194 GR 2H nut standard. A194 GR 2H nut material can be made of 45 steel, A193 GR B7 bolt material can buy B7 material, B7 material can be bought in China.

A106 is a stainless steel pipe material. A106 seamless steel pipe cracking is a seamless steel pipe used to transport water, oil, gas and other high-temperature fluids. A106 export seamless steel pipe is divided into two types: A106-A and A106-B.

A106 export seamless steel pipe is a widely used steel pipe material at home and abroad, mainly used in construction, machining, electrical, petrochemical and other industries. There are two main production processes, one is cold drawing, and the other is hot rolling, in which the dimensional accuracy of cold drawing is higher than that of hot rolling, and the surface of hot rolled steel pipe is rough. Large-diameter seamless steel pipes are made of hot-rolled steel pipes, and small-diameter seamless steel pipes are cold-drawn process.

The exported A106 seamless steel pipe should be beveled, painted and stamped with plastic pipe at both ends, and the commodity inspection should be carried out before export. The main exporters are Malaysia, the United States, Thailand, Saudi Arabia, Brazil and Italy.

A106 is an American standard material, including A, B, and C, of which A106A is C, Si components, tensile strength grade 330MPa, A106B is C, Mn, Si components, tensile strength grade 415MPa, A106C is C, Mn, Si components, tensile strength grade 485MPa.

where A106A is similar to the domestic 20; The A106B is similar to the domestic Q235; The A106C is similar to the Q345.

Is it a carbide model? I didn't find any of this steel.

Is it a mistake, there should be no in the American standard, and naturally I don't know what grade of steel is equivalent to domestically. For details, please refer to the relevant standards, you can refer to the American fastener standard encyclopedia "IFI 7th Edition", or "IFI 8th Edition", etc.
