S420N normalized plate for pta expansion project

The ASTM A36 I beam has moderate tensile and yield strength because of its low carbon content and no other alloying elements. A36 steel beam S420N normalized plate is commonly used in construction and civil engineering because of its competitive low cost and good welding, forming and processing properties. The hot-dip galvanized carbon steel beam can effectively protect the steel from the corrosion of weather and environment. The amount of zinc S420N normalized plate plating can be customized according to your requirements.

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 S420N normalized plate 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.

Boiler steel mainly refers to materials used to make superheaters, main steam pipes and heating surfaces of boiler fire chambers. Boiler steel is a totally different material from S420N normalized plate. The performance requirements for boiler steel are mainly good welding performance, certain high temperature strength, alkali corrosion resistance, and oxidation resistance. Commonly used boiler steels include open-hearth smelted low-carbon killed steel or electric furnace smelted low-carbon steel, with carbon content Wc in the range of 0.16%-0.26%. When manufacturing high-pressure boilers, pearlitic heat-resistant steel or austenitic heat-resistant steel is used. In recent years, ordinary low-alloy steel has also been used to build boilers.

The company adheres to the business philosophy of "good quality, customer first, honesty and trustworthiness", and strives to provide customers with high-quality S420N normalized plate products and excellent services. Our company's products S420N normalized plate are widely used in petroleum, chemical, power station, boiler and other industries, mainly used in reactors, heat exchangers, separators, spherical tanks, oil and gas tanks, liquefied gas tanks, nuclear energy reactor pressure shells and other equipment.
