BBNsteel is a world-leading corrosion-resistant steel supplier, with a global reach stemming from our secure chain of high-quality steel mills across China. We offer both Q235R, Q345R and A514 Gr P quenched and tempered steel, alongside a catalogue of stainless steel grades for various industries. If you would like to learn more, simply contact our online staff.
The pipeline steel coil A514 Gr P quenched and tempered steel and plates are our main products. And the most popular standard for pipeline steel is API 5L. We mainly supply API 5L grade B (L245), API 5L X42 (L290), API 5L X46 (L320), API 5L X52 (L360), API 5L X56 (L390), API 5L X60 (L415), API 5L X65 (L450), API 5L X70 (L485) pipeline steel coil and plates. Those stteel grades have both PSL1 and PSL2 levels. PSL2 has more strict requirements than PSL1. Besides, we also supply API 5L grade A PSL1 and API 5L X80 PSL2 steel.
The selection principle of steel plate for high-rise building is: it can not only make the structure safe and reliable, but also can save steel and reduce the cost. Different use conditions should have different quality requirements. In terms of the mechanical properties of steel such as A514 Gr P quenched and tempered steel, yield point, tensile strength, elongation, cold bending property, impact toughness etc. are the indicators to measure the quality of steel. In the design of steel structure, the appropriate steel should be selected according to the characteristics of the structure. The selection of steel is not only an economic problem, but also related to the safety and service life of the structure.
The microscopic strength of the A514 Gr P quenched and tempered steel, wear-resistant steel plate refers to the strength of the hard phase, but the higher the strength, the higher the wear resistance. Strength is the basis of high-quality wear resistance of wear-resistant steel plates, but the relationship between strength and wear resistance is not proportional; wear-resistant steel plates are often wear-resistant, the root cause is that there are hard particles and soft conventions.

The gas cylinder steel is one of our featured products. The pickled LPG steel is available. We supply gas cylinder steel coil, gas cylinder steel sheet and gas cylinder A514 Gr P quenched and tempered steel steel plates. Welcome to consult any question about gas cylinder steel or LPG steel, such as JIS G3116 SG295 coil price, SG255 material properties, SG325 plate dimensions, HP265 equivalent, P245NB steel properties, etc. We are always here to serve you.
The after-sale service of iron and steel products includes after-sale tracking service, technical guidance, transfer of relevant bills, handling of objections and many other contents. The handling of quality objections accounts for a large proportion. When dealing with these problems, we should distinguish the responsibilities, and compensate or return the inconvenience or loss caused to users due to steel.
