What is the elongation of hardox 450 steel thermo-mechanical condition

The company adheres to the "variety, quality and efficiency" road. We have established a technology center, a brand cultivation management system and a quality control system. Now the company has formed an independent innovation system integrating elongation of Hardox 450 steel production, learning, research and marketing. Our company has passed ISO9001 quality management system certification and ISO10012 measurement management system certification.

Pipeline steel refers to a type of steel with special requirements used for the transportation of oil, natural gas and other pipelines. Depending on the thickness and subsequent formation, pipeline steel can be produced by hot continuous rolling machines, furnace coil machines or plate machines, and formed into large-diameter steel pipe by spiral welding or UOE straight seam welding. The current development trend of elongation of Hardox 450 steel pipeline engineering is large-diameter, high-pressure rich gas transportation, high cold and corrosive service environment, and thickening of submarine pipelines.

Boiler steel plates for room temperature and medium temperature (below creep temperature) are mostly carbon steel, including carbon steel, carbon manganese steel, carbon manganese silicon steel, elongation of Hardox 450 steel, etc. They are mainly used in the manufacture of pressure-bearing parts such as boiler drums and header end covers below medium temperature. High temperature (above creep temperature) boiler steel plates are mainly used to manufacture high-temperature pressure-bearing parts such as high-temperature header end caps and steam pipe blocking plates.

The wear-resistant layer of wear-resistant steel plate is mainly composed of high-carbon and high-chromium alloy. According to the requirements of different users and service conditions, elongation of Hardox 450 steel, the high-temperature wear-resistant steel plate also contains alloy elements such as Mo, W, V, B, Nb, Ti, etc. The microstructure of the wear-resistant layer is eutectic + M7C3-secondary carbide or complex carbide. It can achieve high wear resistance of normal temperature, high temperature, strong impact, medium impact, and low stress impact.

Mechanical properties for elongation of Hardox 450 steel, A213 T36 steel pipe: Tensile strength(min): 415Mpa; Yield strength(min): 205Mpa; Elongation: 30%; Hardness, HB: 163max.

The company has sufficient stocks and complete specifications. The common carbon steel plates, marine plates, elongation of Hardox 450 steel and storage tank steel plates sold are all produced by large state-owned steel companies such as Shougang, Hegang, Taiyuan Iron and Steel, with quality assurance and worry-free after-sales. The company develops and grows under the concept of seeking innovation in stability and advancing with the times for development. After a short period of development, it has begun to take shape.

Both parties shall confirm the elongation of Hardox 450 steel material object and the quality of the products, confirm the reasons for the defects and the quality of the products, and sign the quality inspection agreement. Major quality objections shall be reported to relevant leaders in a timely manner, and shall be discussed and solved with the elongation of Hardox 450 steel steel plant.
