hardox 450 machining biggest 5 mills Sweden
Steel material has an irreplaceable role in many projects, especially in building construction, bridge cofferdams, road construction, foundation pit support, garden engineering, excavator paving, subgrade engineering and other projects. Therefore, the quality of Hardox 450 machining steel material can not be ignored, so how should customers identify the authenticity of steel when choosing steel materials? Today we would like to analyze it together. So that it can help you to purchase satisfied steel materials in the future.
After-sales service team is a key department to test the steel quality. Product quality is always the foundation of our survival and development. The company's full inspection from raw materials to finished products; and implements standardized, scientific, and strict internal quality control and management systems in accordance with the process flow during the production process; products can only leave the factory if qualified, and follow-up problem solving systems are implemented in after-sales services to guarantee the customers’ interest.
Hydrogen (H) is the most harmful element in general steel such as Hardox 450 machining. Hydrogen dissolved in steel will cause hydrogen embrittlement, white spots and other defects. Hydrogen, like oxygen and nitrogen, has very little solubility in solid steel. It dissolves into liquid steel at high temperature, and accumulates in the structure without time to escape when cooling, forming high-pressure micro pores, which greatly reduce the plasticity, toughness and fatigue strength of steel, and even cause cracks and brittle fracture in severe cases. "Hydrogen embrittlement" mainly occurs in martensitic steel, but not very prominent in ferrite steel, and generally increases with hardness and carbon content.
