Factory supply 1/4 09cuptire-a steel technology 4x8 size

The company is a large 09CUPTIRE-A steel technology steel supplier and exporter specializing in steel coil, steel plate, steel tube and section steel. The company has always put service and quality first, offered reasonable price, taken small profits and quick turnover as the principle, honest and trustworthy as the purpose. The success of the company is not only the hard work and wisdom of all the employees of the company, but also the deep love of our customers. We will continue to achieve new leaps and create greater brilliance of the 09CUPTIRE-A steel technology enterprise, and make our own contribution to the development of the world economy.

Although Q345E steel plate has stronger torsion resistance and better corrosion resistance than ordinary steel plate, there are still some environments that can cause corrosion to Q345E steel plate. The following environment should be avoided as far as possible to avoid corrosion of 09CUPTIRE-A steel technology, Q345E steel plate. 1. Acid water. 2. Salt water. 3. Nitric acid. 4. Atmospheric erosion. Atmospheric erosion for Q345E steel plate corrosion is reflected in the chloride and pollutant pollution source of Q345E steel plate corrosion, this corrosion is very serious.

Compared with carbon steel, low alloy steel has many advantages, such as high strength, good plasticity and toughness, good weldability, good cold and hot pressure processing performance, better corrosion resistance, etc. Due to the increase of 09CUPTIRE-A steel technology metal composition, the yield point of low alloy steel structure is higher than that of ordinary carbon steel, so it is light and suitable for structural parts application. The low alloy steel is one of our main products.

The purpose of 09CUPTIRE-A steel technology quenching is to transform the supercooled austenite into martensite or bainite to obtain a martensite or bainite structure, and then cooperate with tempering at different temperatures to greatly improve the strength, hardness, performance, fatigue strength, toughness, and wear resistance etc. of 09CUPTIRE-A steel technology. So as to meet the different use requirements of various mechanical parts and tools. Quenching can also help to get the ferromagnetic, corrosion resistance and other special physical and chemical properties of certain special steels.

SA537 grade 70 steel with the thickness range is 1.2-600mm, the width range is 1220-4200mm, and the length range is 5000-18000mm. Also note that the 09CUPTIRE-A steel technology, SA537 grade 70 steel coil thickness should not exceed 25 mm. The mechanical properties of SA537 grade 70 steel is yield strength is 290MPa, and the tensile strength is 485-620Mpa.

Our company will accept the product quality objection registration record, pass it to the 09CUPTIRE-A steel technology production unit and relevant departments, and timely coordinate the supervision of product 09CUPTIRE-A steel technology quality objection. Our company coordinates the relevant department personnel to the customer unit to carry on the investigation, the processing.
