SPA-H Steel Description

SPA-H Weathering Steel belong the JISG3125-2015 standard, Origin of Japan. SPA-H steel also named atmospheric corrosion-resistant steel. SPA-H weathering steel is made by adding a small amount of corrosion-resistant elements such as Cu, P, Cr, Ni. When the weathering steel of SPA-H is exposed to the air, it will form a dense oxide film on the surface after contact with air and moisture, and the copper, nickel and other elements in it will adhere to the surface, forming a protective barrier against the continuous erosion of the outside world. barrier. The interior can remain in good condition for many years without being damaged. While ordinary steel plates are exposed to the outside world over time, oxidation will continue to erode inside.

SPA-H Weathering Resistant Steel not only has excellent corrosion resistance, but also has good dimensional accuracy, plate type, surface quality and formability indicators, meeting the requirements of container steel, and SPA-H weathering resistant steel is widely used in the container manufacturing industry. SPA-H Weathering steel is also used in landscape architecture, railways, vehicles, bridges, towers, photovoltaic, high-speed engineering and other steel structures exposed to the atmosphere for a long time. SPA-H steel is used to manufacture containers containing hydrogen sulfide corrosion medium and other structural parts in containers, railway vehicles, petroleum derricks, seaport buildings, oil production platforms and chemical and petroleum equipment.
