09cuptire-a steel tube pipe impact test

The quality inspection department is responsible for the inspection management of raw materials and finished products, and the quality inspection and acceptance of products and raw materials. Strictly abide by the company's management system, conscientiously exercise the management power given by the company, and put an end to all ultra vires; be responsible for the inspection of all kinds of raw materials entering the company, and put forward quality problems and handling opinions.

Ordinary 09CUPTIRE-A steel tube pipe carbon steel mainly refers to the steel whose mechanical properties depend on the carbon content in the steel, and generally does not add a lot of alloy elements. Ordinary carbon steel is the abbreviation of ordinary carbon structural steel. Carbon content is less than 0.38%, and less than 0.25% is the most commonly used. It belongs to low carbon steel. In the Chinese standard, each metal grade indicates the low yield point of the steel when the thickness is less than 16mm. Compared with high-quality carbon steel, the limitation of carbon content, performance range, phosphorus, sulfur and other residual elements is wider for ordinary carbon steel.

09CUPTIRE-A steel tube pipe, Wear resistant steel plate has good wear resistance:The chemical composition of the alloy wear-resistant layer is 4-5% carbon and 25-30% chromium. The volume fraction of Cr7C3 carbide in the metallographic structure is more than 50%. The macro hardness is HRC56-62 and the hardness of chromium carbide is HV1400-1800. Because the carbides are distributed perpendicularly in the direction of wear, even when compared with cast alloys of the same composition and hardness, the wear resistance is more than doubled.

The results of adopting two-level 09CUPTIRE-A steel tube pipe service system and implementing standardized management are mainly reflected in the formation of vigorous work style such as quick response and quick action. Our company's customer service center stipulates that employees must be accurate and quick in technical support and 09CUPTIRE-A steel tube pipe after-sales service. Through the formation of this fast, agile, vigorous style, to provide users with satisfactory service.

We have a professional production team and high-quality production equipment, and we also have a great 09CUPTIRE-A steel tube pipe advantage in price, with its own factory, large-scale production to reduce the price. Strictly control each production line to ensure the 09CUPTIRE-A steel tube pipe production of high-quality steel plates, steel pipes and other products that meet customer requirements.
