Superior craftwork on SPA-H weathering resistant steel

SPA-H High strength weathering steel mainly used at container industry, that because the carbon steel will very easy to corrosion at the air. Then SPA-H will cause the great economic loss.

SPA-H mechanical property is superior, because the Yield strength, tensile strength and elongation are stable and fluctuation scope small. We have done the SPA-H materials which is far more than standard requirement.

For the SPA-H chemical 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.

Our SPA-H materials corrosion test using the DW-UD-3 Dry-wet compound cycle test rig simulation for atmospheric corrosion environment. The test by 120 hours. So let the SPA-H steel corrosion rate was 2.33g/ (m22h). And the Q235B CORROSION RATE is 3.52g/ (m22h). That can check the difference.

Our company Bebon Steelused 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 manufacturing.
