The company adopts the BS700MC weldable structural steel international advanced management system, and has passed the certification of ISO9001 quality management system, ISO14001 environmental management system and GB / T28001-2001 occupational health and safety BS700MC weldable structural steel management system, and has realized the comprehensive integration of the three systems. In the future development path, the company will adhere to the guidance of scientific development concept, accelerate the implementation of six development strategies, namely, the main business development strategy, cost leading strategy, science and technology innovation strategy, management upgrading strategy, green steel strategy, and Harmonious Co construction strategy, promote the company's sustainable development, and build the company into the most competitive modern steel group.
How to choose the material and specification of BS700MC weldable structural steel, boiler tube? First, select the specification according to the actual use. Secondly, material: the suitable boiler tube material is different for different use scenarios. Thirdly, the wall thickness of the boiler tube should be strictly in accordance with the relevant standards. If the thickness is not up to standard, it is easy to cause accidents, so it must be strictly controlled. Finally, the boiler tube should be checked in time when receiving the goods, and the relevant instruments should be used to detect whether the steel quality has reached the standard, if not, it can be rejected.
Wear resistant steel is very wear-resistant: for example, excavator bucket, long-term excavation requires good wear resistance. Wear resistant steel has a very high hardness: for example, scraper conveyor, if the hardness is not up to standard, it is extremely easy to fracture, resulting in very serious consequences. Wear resistant steel has good corrosion resistance: many equipment need to transport chemical corrosion products, so corrosion-resistant mechanical equipment is needed. BS700MC weldable structural steel, Wear resistant steel has good fatigue resistance: such as bearing steel ball, which can do fast and repeated movement, and need to guarantee performance.
The allowable temperature of BS700MC weldable structural steel, boiler steel is mainly determined by strength condition. Different steels have different mechanical properties and high temperature properties. Even for the same kind of steel, the tensile strength, yield strength and rupture strength vary greatly with the working temperature, and decrease with the increase of working temperature. In order to ensure the safety of BS700MC weldable structural steel work, the actual stress of BS700MC weldable structural steel under the working temperature should be less than the allowable stress determined by the tensile strength, yield limit and permanent strength of BS700MC weldable structural steel under the temperature.
According to GB 11251 technical standard, the chemical composition of 40Cr structural steel plate is as follow: Carbon content is 0.37-0.44 %, Silicon content is 0.17-0.37%, Manganese content is 0.50-0.80%, Chrome content is 0.80-1.10%. 40Cr steel is usually in shape of 40Cr steel plates and bars. BS700MC weldable structural steel, GB 11251 is for 40Cr structural steel plate with thickness range of 4-30mm. The tensile strength of 40Cr structural steel plate is 550-800Mpa. And its min. Elongation is 16%.
For ASTM A573 Grade 70/A573 Gr.70 carbon manganese silicon steel plates, our company would issue the original mill test certificate BS700MC weldable structural steel EN 10204 3.1 for clients when arrange delivery, so that clients can trace the A573 Gr.70 plates origin easily.
Our company will accept the product quality objection registration record, pass it to the BS700MC weldable structural steel production unit and relevant departments, and timely coordinate the supervision of product BS700MC weldable structural steel quality objection. Our company coordinates the relevant department personnel to the customer unit to carry on the investigation, the processing.
