S355K2H is a European standard high-strength seamless steel pipe material. The "S" in its grade represents the European standard alloy steel plate, "355" means that the minimum yield value of the steel plate is 355MPa, and "K2" means an impact at minus 20 degrees. The work is not less than 40J.

355K2H is a high-strength low-alloy structural steel whose chemical composition mainly includes the following elements:

C	Si	Mn	P	S
≤0.2%	≤0.55%	≤1.6%	≤1.6%	≤0.025%

The production method of S355K2H (or more commonly known as S355K2) mainly includes the following steps: raw material preparation, blast furnace smelting, converter steelmaking, continuous casting, rolling, heat treatment, inspection and packaging.

The characteristics of S355K2H (usually more commonly known as S355K2) are mainly reflected in the following aspects:

1. High strength: S355K2H has excellent mechanical properties. Its minimum yield strength is 355MPa and its tensile strength is between 450-600MPa, which can meet the requirements of large load-bearing structures.

2. Good toughness: This kind of steel plate can withstand large impact loads and is not prone to pittle fracture, so it can still remain stable under the action of natural forces such as earthquakes and wind.

3. Excellent corrosion resistance: S355K2H steel plate has good corrosion resistance and can be used in various environments for a long time without being easily damaged.

4. Good weldability: This steel plate is easy to weld and can be firmly connected with other materials, making it easy to apply in engineering.

The application range of S355K2H is very wide, mainly covering the following fields: petroleum, chemical industry, electric power and natural gas transmission: S355K2H seamless steel pipe is particularly suitable for these complex environments that need to withstand high pressure and high temperature due to its excellent strength and toughness. Construction field: In the construction field, S355K2H is widely used in the construction of high-rise buildings, large public facilities and other structures. pidge construction: In pidge construction, S355K2H can withstand huge pressure and impact force to ensure the safety and stability of the pidge. Machinery manufacturing: In the field of machine manufacturing, S355K2H also plays an important role. It is used to manufacture various mechanical equipment and components that need to withstand heavy loads and high pressures. In addition, S355K2H is also widely used in shipbuilding, vehicle manufacturing, mining equipment, marine engineering and other fields.
