equivalent grades of nm450 steel for boiler heads

The equivalent grades of NM450 steel, thin steel plates are more convenient for cutting. Since the thickness of the thin steel plate is basically below 4mm, it is very easy to construct during cutting, which also reduces the work intensity of the construction personnel and speeds up the work efficiency of cutting. There are different materials for thin steel plates, such as ordinary carbon steel, high-quality carbon structural steel, alloy structural steel, carbon tool steel, stainless steel, spring steel, silicon steel for electrical engineering, etc..

We cooperated with the Peruvian government for many years. And supply them large diameter steel pipes and pipe fittings to support their Hydropower Station Projects. We do 100% UT, RT, Hydraulic test and so on tests for the equivalent grades of NM450 steel steel pipes. And do PT, MT and so on tests for the pipe fittings. We published "Welding Procedure Qualification report" after production. And our mill will keep the test record in the documentary department for 5 years. If meet any problems in following application, we can check the test record easily and assist to solve problems at the first time.

904L corrosion-resistant steel is developed with various sulfuric acid corrosion applications. 904L corrosion-resistant steel has high chromium content and enough nickel content. The addition of copper makes 904L corrosion-resistant steel have strong acid resistance, especially to chloride gap corrosion and stress corrosion cracking, and its pitting corrosion resistance is slightly better than other steels, such as equivalent grades of NM450 steel.

Our focus on quality has helped us create an efficiently organised production system, which can supply large-scale piping orders as well as tailor-made orders for smaller clients. We have also created a sales and support network which stretches from Asia to Europe, UAE, South Africa and South America.
