What is SPA-H High strength weathering steel plate

SPA-H High strength weathering steel plate mainly used at container industry, that because the carbon steel will very easy to corrosion at the air. Then will causes the great economic loss.SPA-H High strength weathering steel plate mechanical property, because the Yield strength, tensile strength and elongation is stable and fluctuation scope small. We done the SPA-H materials which is far more than standard requirement.

For the SPA-H High strength weathering steel platechemical composition, Our mill though the way of Smelting processing, through the end point control of converter, reducing repair times and reduce the oxygen content in steel, improve the yield of alloy elements, stabilize the composition of molten steel. Then let the alloy element content is higher and is stable.
 
The yield strength of SPA-H High strength weathering steel plate is lower, easy to forming, High work hardening rate, Used performance is nice.At the surface quality and boundary dimension, Using the hot coil box at the hot rolling processing, that better guarantee the cleaning rod coil temperature uniformity. Rolling line descaling system normal operation, the strip's surface is bright and cleanly after rolling. No tin oxide pressure and surface crack.SPA-H High strength weathering steel plate 's thickness and width of the control precision is high, the actual deviation is within the scope of the technical requirements, precent of pass is 100%.
 
The users of ours for SPA-H High strength weathering steel plate think our container used corten steel's hot rolled plate size and plate shape control is good, Thickness fluctuation is small, steel strip surface quality and formability is good. One time molding can reach the goal request. Not found the crack, peeling and so on at the form processing, that can completely meet the requirement of container manufacturing. 

We also could supply other weathering steel plates, for example, 09CuPCrNi-A, 05CuPCrNi, SPA-H, SPA-C, B480GNQR,Q355GNHD,Q355NHD, S355J0WP and CORTEN-A.Please contact BBN steel if you want to know more information about SPA-H High strength weathering steel plate.
