What is the chemical composition of SPA-H anti weathering corrosion steel sheet?

We are world class steel SPA-H anti weathering corrosion steel sheet materials supplier. We are engaed in providing raw steel materials such as steel plates / steel coils / steel sheets / steel pipes, deep processing and a series project design and solutions to clients. We guarantee to return goods for free for SPA-H anti weathering corrosion steel sheet quality problem during its lifetime. Your satisfactory is our permanent pursue. We always welcome advise from clients to make self-improvement continously. And sincerely to build long-term cooperation with you.

The SA 516 grade 60 steel is remarkably one of the standard steel grades having five chemical elements that are specified with the three mechanical properties. The grade does not require to be heat treated; hence it offers the best properties and features. Our aim is to provide our customers with a high quality of theSPA-H anti weathering corrosion steel sheet product which has all the qualities that an application requires for working. The SA 516 grade 70 plates are widely used in different applications because of its easy to use and installation process.

S235JR steel plate is one mainly of Carbon and low alloy steel, S235JR steel plate is a type of steel sheet under EN standard which is used to build ship, bridge, belongs to high strength sheet. EN10025-2 S235JR is equivalent to DIN:ST37-2,JIS:SS400,ASTM:A283C, GB Q235B and UNI:FE360B.

After extrusion, the SPA-H anti weathering corrosion steel sheet tube shall be removed for sizing. The sizing machine uses a cone-shaped bit to rotate into the steel embryo at high speed to drill holes to form steel pipes. The inner diameter of the steel pipe is determined by the outer diameter length of the drill bit of the sizing machine. After sizing, the steel pipe will enter the cooling tower and be cooled by water spray. After cooling, the steel pipe will be straightened. After straightening, the steel pipe is sent to the metal flaw detector (or hydraulic test) by the conveyor belt for internal flaw detection.

The proportion of main elements in Q345 steel is basically the same as that in 16Mn steel, the difference is that V, Ti, Nb microalloy elements are added. A small amount of V, Ti, Nb alloy elements can refine the grains, greatly improve the toughness of the steel, and greatly improve the comprehensive mechanical properties of the steel. Because of this, the thickness of SPA-H anti weathering corrosion steel sheet, Q345 steel plate can be made larger. Therefore, the comprehensive mechanical properties of Q345 steel should be better than that of 16Mn steel, especially its low temperature properties. The allowable stress of Q345 steel is slightly higher than that of 16Mn steel.

We are known as SPA-H anti weathering corrosion steel sheet leading manufacturers, suppliers and exporters in the market all over the world.
