Is SPA-C high weather corrosion resistant steel or Q235B steel stronger?

The company has allocated special environmental protection facilities for all SPA-C high weather corrosion resistant steel pollution sources, strengthened the recycling of waste resources and improved the efficiency of resource utilization. At present, the recovery and utilization rate of solid wastes such as iron slag, steel slag, iron bearing dust, SPA-C high weather corrosion resistant steel steel mill scale, environmental protection dust has reached 100%.

EN10025-2 S355JR low alloy steel grade is equivalent to GB Q345B in Chinese standard. For the normal thickness, these two steel grades are both owned 345MPa yield strength. Plate S355JR+N indicates that the S355JR steel plate must be done Normalized heat treatment when rolling for improve the steel strength and weldability. Our mill would roll SPA-C high weather corrosion resistant steel, S355JR alloy steel plate under as rolled or control rolled when customers' have not requested any heat treatment in their P/O.

API 5L Gr.B steel plate is one mainly of Steel for large diameter pipes,API-Gr.B steel is manufactured using premium grade of raw material. These products SPA-C high weather corrosion resistant steel are used to flow steam, water, oil and various petrochemicals substance in various petrochemical and chemical industries. These Steel Seamless Pipes are widely appreciated for high performance and less maintenance.

How to distinguish the inferior steel plate? 1. The surface of the fake and inferior steel plate is easy to produce scab. 2. The material of fake and inferior steel plate is not uniform and there are many impurities. The surface of fake and inferior steel plate is often pitted. Pitting is an irregular and uneven defect on the surface of SPA-C high weather corrosion resistant steel, steel plate caused by serious wear of rolling groove. Due to the pursuit of profit by the manufacturers of fake and inferior steel plates, the groove rolling often exceeds the standard.

GB/T 1591-2008 Q460E material is a high strength low alloy steel plates. Q460E steel product size SPA-C high weather corrosion resistant steel: 3*1500*5900, 4*1500*6000, 48*3130*10100, 47*2610*8450, 3*1500*6000, 6*2000*8000, 48*2880*8550, 48*3130*10400, 5*1500*4150, 10*2000*8000, 48*2610*8700, 48*3170*10800, 5*1500*6000, 8*2000*2800, 47*2600*7000, 48*2880*3900, 16*2160*3300, 8*2000*8000, 47*2610*8700, 48*3150*10700, 5*1500*6000, 48*3130*10400 (mm).
