What are the common uses of SPA-H steel section

We are a popular factory, supplier and wholesaler of mild steel plates and alloy steel plates in all over the globe. We follow all standards and specifications of SPA-H steel section boiler steel plate, structural steel plate, shipbuilding steel plates and corten steel in different types. We manufacture and supply steel plates, steel section and steel structures according to customer’s demand. The company also focus on providing customers with SPA-H steel section high-end steels and competitive price.

SA516 Grade 70 SPA-H steel section refers to normalized steel products. For steel plates and thin plates with a thickness of less than 40mm, we usually supply rolled steel coils. Plates with a thickness greater than 40mm should be normalized and supplied. The density of SPA-H steel section SA516 70 grade steel plate is 0.284 cu/in3 (7861 kg/m3).

Strong pressure resistance of SPA-H steel section, boiler steel tube: The wall thickness of boiler steel tube is very important, because the steam pressure is very large, if the wall thickness is very thin, it will be broken by the steam pressure released instantly. The boiler steel tube has good high temperature resistance performance: the steam temperature in the pipeline can reach hundreds of degrees Celsius above. If the high temperature resistance performance is not enough, the boiler steel tube will be melted by the high temperature brought by the steam.

Chromium molybdenum steel, also known as medium temperature hydrogen resistant steel, refers to the steel added with Cr (≤ 10%), Mo and other alloy elements to significantly improve the high-temperature strength limit and creep limit, and has good hydrogen corrosion resistance and high-temperature resistance performance. SPA-H steel section, Chromium molybdenum steel is widely used in oil refining, chemical and other hydrogen containing devices and high-temperature equipment, and is one of the commonly used steels for pressure vessels.

P235GH steel material number under EN10028-2:2003 standard is 1.0345. This steel is a European pressure vessel steel. P235GH Mechanical properties: Tensile strength σb (350 ~ 480 MPa); Yield strength σs(215 MPa min.); Elongation ≥25%; Brinell hardness ≤105 ~ 140. SPA-H steel section, P235GH steel chemical composition (mass fraction,%): ≤0.16 C; ≤0.35 Si; 0.60 ~ 1.20 Mn; ≤0.025 P; ≤0.010 S; ≤0.30 Cr; ≤0.30 Ni; ≤0.30 Cu; ≤0.08 Mo; ≤0.02 V; ≤0.02 Nb; ≤0.012 N; ≤0.020 Al; ≤0.03 Ti.

Hot rolled plates are known for their superior mechanical properties over commodity grades of merchant bar. The hot rolled SPA-H steel section plates products are made to specific chemistry and mechanical properties ranges, allowing them to be used in engineered applications. Resulting shafts, axles, and gears can be used in the automotive SPA-H steel section industry and agriculture equipment. A36 mild steel has good strength, formability, and excellent welding properties. We also can supply welding, fabricating, and bending service.

After the order is finished, our after-sales service center will send an email to make a feedback about our steel products' quality. We have phone service every three months to remind our customers of the possible problems and collect advices or suggestions in quality and service. Upon the collection of advices or suggestions, our after-sales service will quickly make technical solutions to wipe out the customer problem.
