Material SMA400AP steel exhaust pipe grade density

The company adopts modern management concept, adheres to “quality for survival, integrity for development”, and provides customers with high-quality and reliable steel SMA400AP steel exhaust pipe products and wholehearted service. The company continuously deepens the internal reform of the enterprise, innovates in the reform, develops in the innovation, and gradually forms a set of management and operation mechanism which adapts to the SMA400AP steel exhaust pipe market and has strong competitiveness.

The JIS G3106 SMA400AP steel exhaust pipe specification is a hot-rolled carbon steel plate for welded structures. The SMA400AP steel exhaust pipe steel grades include: SM400A/B/C, SM490A/B/C, SM490YA/YB, SM520B/C, SM570.

Grade E, Grade EH32, Grade EH36 series shipbuilding steel products have good comprehensive mechanical properties, welding performance, process performance. Our shipbuilding steel plate and SMA400AP steel exhaust pipe steel sections are suitable for manufacturing structural parts such as ship hull structures, docks, oil production platforms, marine transmission pipelines, coastal power plants, wharf facilities in ocean, coastal and inland navigation areas.

Both the cross rolling method and the extrusion method must first heat the tube blank or ingot, and the steel tube produced is called hot rolling tube. Steel pipes produced by hot working can sometimes be cold worked as required. There are two methods of cold working: one is cold drawing, that is, drawing the SMA400AP steel exhaust pipe steel pipe through the drawing die to make the steel pipe gradually thin and elongate; the other is cold rolling, which is the method of applying the hot rolling mill invented by the menesmann brothers to cold working. The cold working of SMA400AP steel exhaust pipe seamless steel pipe can improve the size accuracy and finish of steel pipe, and improve the mechanical properties of materials.

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, SMA400AP steel exhaust pipe. 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.

Before delivering our hot rolled plate product we apply various tests to check the quality of carbon steel SMA400AP steel exhaust pipe plates such as- mechanical test, chemical test, hardness test, toughness test, eddy current test, impact test, micro test, flaring test, flattening test, etc. We are provided best packing for structural steel plates to avoid rust. Our after-sales service team will contact you if you have any question.
