what is duplex stainless steel pipe?duplex stainless steel (dss) including grades duplex 2205(s31803) and super duplex, they are commonly consist of 50% ferrite and 50% austenite, and generally requires not less than 30%. duplex stainless steel has goo

stainless steel welded pipe has super corrosion resistance, especially 316l stainless steel pipe, so it is widely used in the seaside and other corrosive environments. however, even the best stainless steel welded pipe can cause corrosion if used improperly, so it is mainly what are the in

as there are many types of steels, the chance of developing a conflict is guaranteed. different kinds of steel are made of various components. besides, they are different in their use and durability. if you know the manufacturing story, you can quickly determine how it will be useful for y

the main categories of stainless steels are:a) austenitic (200 and 300 series) stainless steelsb) ferritic (400 series) stainless steelsc) martensitic (400 and 500 series) stainless steelsd

carbon steel aisi 1018 is the most commonly available cold-rolled steels. 1018 demonstrates good strength, some ductility, and comparative ease of welding and machining. this material is also chemically similar to a36 hot rolled steel, but cold rolling creates a better surface finish and u

astm a36 steel is one of the most widely used carbon structural steels, although the carbon content of a36 material is maximum 0.29%, it is considered to be the mild steel (content of carbon ≤ 0.25%).a36 mild steel is often compared to ai

a234 wpb steel pipe fittings mean the pipe fitting which material is astm a234 wpb,they are used for the pressure piping systems of moderate and high temperature services. astm a234 is the standard of pipe fittings material,it indicates the materials properties of different kinds of c

roughly speaking, seamless steel pipe manufacturing process starts with a solid, round steel billet. this billet is then heated to great temperatures and stretched and pulled over a form until it takes the shape of a hollow tube. it is different from the welded pipe which is produce

when it comes to variations between 304 and 304l stainless steel, an essential thing to note is the latter’s greater immunity to intergranular corrosion. intergranular corrosion is the cracking that can occur along grain boundaries of steel in the presence of tensile stress.<
