S355K2H is a high-strength low-alloy structural steel whose chemical composition mainly includes carbon (C), silicon (Si), manganese (Mn), phosphorus (P), sulfur (S), etc. The production method of S355K2H mainly includes the following main steps: blast furnace smelting, converter steelmaking, continuous casting, rolling, and heat treatment.
S355K2H, as a European standard high-strength seamless steel pipe, has the following significant features:
1. High strength: The minimum yield strength of S355K2H is 355MPa, which can meet the requirements of large load-bearing structures, making its structure stable and able to withstand the pressure of loads.
2. High toughness: This material has good toughness, can withstand large impact loads, and is not prone to pittle fracture. S355K2H can still remain stable under the action of natural forces such as earthquakes and wind.
3. Good corrosion resistance: S355K2H steel pipe can maintain good corrosion resistance in a variety of environments and is suitable for various complex environments.
4. Excellent weldability: This material is easy to weld and can make good connections with other steel materials, making it easy to construct and install.
The application range of S355K2H is quite wide, mainly covering the following fields: S355K2H seamless steel pipe is often used in petroleum, chemical industry, electric power, and natural gas transportation that need to withstand high pressure and high temperature. Construction steel structure: In the construction field, S355K2H steel pipes are used in construction steel structures such as large venues, exhibition venues, lifting machinery, and storage shelves. pidge and Tunnel Construction: In pidge and tunnel construction, S355K2H steel pipes can be used as supporting members and connectors. Machinery manufacturing: In the field of machinery manufacturing, S355K2H steel pipes can be used to manufacture frames and support structures for various mechanical equipment, such as large cranes, excavators, etc.
