What is high strength hardox 450 steel equivalent IS grade
According to the latest statistics of alacero, the consumption of finished steel high strength Hardox 450 steel products in Latin America in 2019 was 64.2 million tons, down 5% from 67.6 million tons in 2018. The decline in steel consumption in the region reflects the economic contraction of Latin American countries, especially the three major economies: Mexico, Argentina and Brazil. The three countries accounted for 87% of the total reduction in high strength Hardox 450 steel steel consumption in Latin America. Alacero said the main reasons for the decline in steel consumption in the region are the global economic slowdown, the fall in commodity prices, trade disputes between the United States and its partners, the shrinking world trade high strength Hardox 450 steel and political uncertainty, as well as the negative impact on Latin American countries and their neighbors in terms of investment.
The company has a perfect after-sales service system and quality assurance system. The company adheres to the service principle of "all for users", and has established a professional after-sales service team.

Boiler steel refers to the special steel used to manufacture pressure components of steam boilers, such as steam drums. The boiler steel mainly means boiler steel plates and seamless boiler steel pipes. Boiler components not only bear pressure loads but are also heated by direct fire, so the requirements on the chemical composition and mechanical properties of boiler steel, high strength Hardox 450 steel are strict. In the chemical composition of boiler steel, high strength Hardox 450 steel, sulfur and phosphorus are strictly controlled. Tensile strength, yield point, elongation, impact energy value and 180 ° cold bending are required to be tested in boiler steel mechanical properties. In addition, strain aging impact test is also required for boiler steel. The quality control of boiler steel is slightly higher than that of pressure vessel steel.
After years of operation and accumulation, the company has formed an operation network covering major economic cities across the country, with a group of high-quality professional logistics technicians and management personnel, strong strength and stable logistics channels. The company's business operations include the loading and unloading of steel raw materials and finished materials, high strength Hardox 450 steel warehousing, and freight transportation. Our logistics service business has passenger transportation, automobile and construction machinery inspection, logistics information management and operations.
The effect of nitrogen on steel performance is similar to that of carbon and phosphorus. With the increase of high strength Hardox 450 steel nitrogen content, the strength of steel can be improved, plasticity especially toughness can be significantly reduced, weldability becomes worse, and cold brittleness is intensified. Nitrogen with aluminum, niobium, vanadium and other elements can reduce its adverse effects, improve the performance of high strength Hardox 450 steel steel, can be used as an alloying element of low alloy steel.
