Carbon steel plate | The carbon steel plate has usually been considered as steel that does not contain any alloy steel elements. Generally, elements are C, Mn, P, S, Si, besides these, there are no minimum limits for elements of Al, Cr, Ni, Mo, V, etc. Carbon steel plates are available in different grades depending on carbon content and strength.

Pipeline Steel Plate | Pipeline steel plates are used to fabricate large diameter welded pipes which transportation oil and natural gas, also known as pipe steel plates. Now more and more world's people focus on protecting our environment, new clean energy natural gas is widely used through pipelines. These pipeline steel plates own ability to resist high pressure, atmospheric corrosion and lower temperature surroundings.

Weather-resistant steel plate | Weather Resistant Steel Plates are used in applications that last longer and are exposed to the atmosphere for the long term. Applications that have to have plates in the open often use these Corrosion Resistant Steel Plates in combination with pipes, fittings, and flanges. The material can vary in composition but all the weathering steel types have low carbon, less than 0.3% by weight. This low carbon allows for the ductility and toughness of the Weather Resistant Steels Sheet. The name comes from the ability of the material to withstand weathering or atmospheric conditions over time. The specialty of the Corten Weather Resistant Steels is that it forms an oxide layer on the surface. This oxide layer cannot oxidize any further, so it acts as a barrier between the steels inside the layer and the oxidizing agents to the outside of the plates.

Wear-resistant steel plate | Wear-resistant steel plate, also called abrasion-resistant or AR plate, is made from steel billets and comes in many grades. Alloys like carbon, manganese, nickel, chrome, and boron are added in different proportions. The grades, therefore, have different mechanical and chemical properties that will produce different results in an end product. Wear-resistant steel is tougher and harder than conventional steel plate and can last up to 4 times longer than conventional high-strength steel. NM360 , NM400, NM450, NM500 |
