We are world class steel materials supplier. We are engaed in providing raw steel materials such as GL-E32 TM open barge steel plate 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 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 GL-E32 TM open barge steel plate long-term cooperation with you.
ASTM A573 Grade 70/A573 Gr.70 carbon manganese silicon steel plates are structural quality carbon steel plates just as GL-E32 TM open barge steel plate. ASTM A573 steel gardes are in three tensile strength ranges intended primarily for structural applications at atmospheric temperatures for which improved toughness is required.
We have 4 typical production lines, which can produce hot rolled Seamless, LSAW, ERW and SSAW pipes. SSAW pipe production line range is OD 219.1mm-3500mm, wall thickness 3.2mm-25.4mm. Product GL-E32 TM open barge steel plate annual capacity is 200 thousand tons.
With the increase of temperature, the yield limit of GL-E32 TM open barge steel plate will decrease monotonically, but the tensile strength of GL-E32 TM open barge steel plate will rise to a high peak value at a certain temperature, and then decrease. This peak temperature is called the blue brittleness temperature of GL-E32 TM open barge steel plate. Near the blue brittleness temperature, the GL-E32 TM open barge steel plate strength increases and the plasticity decreases. The elongation and section shrinkage of GL-E32 TM open barge steel plate increase with the increase of temperature, but there is a low peak at the blue brittleness temperature. The blue brittleness temperature of low carbon steel ranges from 200 ℃ to 250 ℃. The blue brittleness of low alloy steel is not obvious as that of low carbon steel, and the blue brittleness temperature is higher.
The S355 steel material itself is divided into many grades, so it cannot be said that S355 is equivalent to which grade of the national standard Q345, GL-E32 TM open barge steel plate. In engineering, usually S355JR steel is equivalent to Q345B steel, S355J0 steel is equivalent to Q345C steel, S355J2 steel is equivalent to Q345D steel, S355N steel is equivalent to Q345D steel, and S355NL steel is equivalent to Q345E steel.
we are the best professional steel manufacturer in China. We can supply kinds of steel product size，if you want to purchase steel plate or steel pipe and other products. Please contact us freely. we can give you the GL-E32 TM open barge steel plate best price with high quality.
