TMCP process is an indispensable technology for our production of low alloy high strength wide and RINA grade A floating dock steel thick steel plates. TMCP process can produce steel with high strength and toughness without adding too many alloy elements and complex subsequent heat treatment. TMCP is a process that can save alloy RINA grade A floating dock steel and energy and is beneficial to environmental protection. A lot of our shipbuilding steel plates are produced by TMCP process.
Based on the principle of win-win and mutual benefit, the company operates in good faith, strictly controls the quality, and provides perfect after-sales service, which has won unanimous praise. The success of the company is not only the RINA grade A floating dock steel hard work and wisdom of the company's employees, but also the deep love of the majority of consumers. It also inspires all employees of the company to have the courage to strive. We will continue to innovate and leap forward, create greater brilliance of the enterprise, and make our own contribution to the development of the RINA grade A floating dock steel steel industry.
The factory is located in the central China, with convenient transportation and abundant resources. The main products are various construction steel plates, steel pipes, steel sections, and steel structure processing parts. Used in the RINA grade A floating dock steel manufacture of railway tracks, pressure vessels, boilers, hulls, bridges, various types of steel, etc. With an annual output of 2.23 million tons of steel plates, 2.04 million tons of steel pipes and 1.54 million tons of section steel in 2002, it is an important pig iron base in Henan Province.
Hydrogen (H) is the most harmful element in general steel such as RINA grade A floating dock steel. 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.
