SM490B plate is a kind of structural steel produced according to Japanese Standard JIS G3106. Min. tensile strength of SM490B plate is 490MPa. SM490B plate is mainly used in buildings, bridges, ships, rail vehicles, oil tanks, containers and other buildings requiring high-level weldability. The delivery state is hot rolling for SM490B plate, RINA grade B corrugated bulkhead steel with thickness less than 80mm; and the delivery state is normalizing for SM490B steel plate with thickness more than 80mm.
Common carbon killed steel plates are steel plates made by hot-rolling ordinary carbon structural steel killed billets. The advantage of RINA grade B corrugated bulkhead steel, killed steel is that the chemical composition is uniform, so the mechanical properties of each part are also uniform, the welding performance and plasticity are good, and the corrosion resistance is strong. Common killed steel plates are mainly used to produce components that withstand impact at low temperatures, welded structures and other structural parts that require higher strength.
In the cutting process of wear-resistant plate, RINA grade B corrugated bulkhead steel, the steel plate is processed first, because the steel plate is cut after cutting and marking; the commonly used cutting methods for wear-resistant plate are CNC flame cutting and numerical control water cutting, the cost of numerical control flame cutting is not very high, it belongs to primary processing, and its processing range is from 3 mm to 100 mm steel plate. And numerical control water cutting is mainly used under the condition that cutting is required not to deform.
The high strength RINA grade B corrugated bulkhead steel low alloy steel, which is shorten as HSLA steel, is one of our main products. We have professional team to serve you. For any demands or questions about HSLA steel, for example, ASTM A572 grade 50 chemical composition, difference between S355JR and S355J2, mechanical properties of RINA grade B corrugated bulkhead steel ST52 steel, Q345B tensile strength, Q345D steel ASTM equivalent, HSLA steel price etc. , please do not hesitate to contact us and consult.
Our quality and service commitment: RINA grade B corrugated bulkhead steel product quality problems, life-long replacement.In the process of using, any time if you find we supplied steel materials not conform to the requirements of technical standards, we can replace it for you free of charge.
