The main products of BBN steel are carbon steel, mild steel and low alloy steel plates. Our business scope are ASTM carbon steel, EN carbon steel, Chinese carbon steel materials, JIS carbon steel, ASME carbon steel, DIN carbon steel, etc. The main steel grades are A36, A283C, A572 Gr 50, S235JR, S355JR, SS400, Q235, Q345, JIS SM490YA plates etc. The company has a sound quality assurance system. In order to open up the market and realize mutual benefit, we will serve our customers wholeheartedly with the business philosophy of "price, quality" and "integrity, service"

Ordinary carbon structural steel JIS SM490YA plates has many impurities and low price. The ordinary carbon structural steel is used in places with low performance requirements and low strength, but it has good plasticity, toughness and cold deformation performance. High quality carbon structural steel has less harmful impurities, and its strength, plasticity and toughness are better than those of ordinary carbon structural steel. High quality carbon structural steel is mainly used to manufacture important mechanical parts.

The proportion of main elements in Q345 steel is basically the same as that in 16Mn steel, the difference is that V, Ti, Nb microalloy elements are added. A small amount of V, Ti, Nb alloy elements can refine the grains, greatly improve the toughness of the steel, and greatly improve the comprehensive mechanical properties of the steel. Because of this, the thickness of JIS SM490YA plates, Q345 steel plate can be made larger. Therefore, the comprehensive mechanical properties of Q345 steel should be better than that of 16Mn steel, especially its low temperature properties. The allowable stress of Q345 steel is slightly higher than that of 16Mn steel.

Our company will accept the product quality objection registration record, pass it to the JIS SM490YA plates production unit and relevant departments, and timely coordinate the supervision of product JIS SM490YA plates quality objection. Our company coordinates the relevant department personnel to the customer unit to carry on the investigation, the processing.
