Thép không gỉ so với thép mạ kẽm

Introduction Stainless Steel vs Galvanized Steel, it’s crucial to consider the environment, required durability, and maintenance needs. Stainless steel offers unmatched corrosion resistance, strength, and visual appeal, making it suitable for demanding applications in harsh environments. Galvanized steel, on the other hand, offers cost-effective corrosion protection for less aggressive settings. 1. Composition and Manufacturing Process […]

Sự tiến hóa của cấu trúc vi mô của thép P92 ở các nhiệt độ đẳng nhiệt khác nhau

Microstructure Evolution of P92 Steel at Different Isothermal Temperatures P92 steel is mainly used in ultra-supercritical boilers, ultra-high-pressure pipelines, and other high-temperature and high-pressure equipment.P92 steel is in the P91 steel chemical composition based on the addition of trace elements of W and B elements, reduces the content of Mo, through the grain boundaries of […]

ASME B31.1 so với ASME B31.3: Tìm hiểu về các quy định thiết kế đường ống

Introduction In piping design and engineering, selecting the appropriate piping code is essential for ensuring safety, efficiency, and compliance with industry standards. Two of the most widely recognized piping design codes are ASME B31.1 and ASME B31.3. While they both come from the American Society of Mechanical Engineers (ASME) and govern the design and construction […]

ASME BPVC Phần II Phần A: Thông số kỹ thuật vật liệu sắt

Introduction ASME BPVC Section II Part A: Ferrous Material Specifications is a section of the ASME Boiler and Pressure Vessel Code (BPVC) that covers specifications for ferrous materials (primarily iron) used in the construction of boilers, pressure vessels and other pressure-retaining equipment. This section specifically addresses the requirements for steel and iron materials, including carbon […]

Phân tích nguyên nhân gây ra vết nứt hình vòng trong ống thép liền mạch SAE 4140 đã tôi

The reason for the ring-shaped crack at the pipe end of the SAE 4140 seamless steel pipe was studied by chemical composition exam, hardness test, metallographic observation, scanning electron microscope, and energy spectrum analysis. The results show that the ring-shaped crack of SAE 4140 seamless steel pipe is a quenching crack, generally occurring at the […]

ASME SA213 T91: Bạn biết bao nhiêu?

Background & Introduction ASME SA213 T91, the steel number in the ASME SA213/SA213M standard, belongs to the improved 9Cr-1Mo steel, which was developed from the 1970s to the 1980s by the U.S. Rubber Ridge National Laboratory and the Metallurgical Materials Laboratory of the U.S. Combustion Engineering Corporation in cooperation. Developed based on the earlier 9Cr-1Mo […]
