Cause analysis of red oxide iron on 09cuptire-a steel grade surface

ASME SA203 is a low-nickel alloy steel, including five grades of A, B, D, E, and F. SA203 Gr.E steel plate impact temperature -101 ° C. SA203 Gr.D / E / F has good impact toughness and mechanical properties under low temperature working conditions, and is usually used in low temperature environments of -70 ～ -101 ℃ (the tempered state can be -107 ℃). 09CUPTIRE-A steel grade Smelting method: It is smelted by electric furnace + refining outside the furnace + vacuum degassing, and should be fine grain killed steel.

NM400 alloy steel plate is a kind of wear-resistant steel plate. NM—The first letter of the Chinese pinyin 400 of the characters “resistant” and “grind” for wear resistance is the HB value of the Brinell hardness value. NM400 alloy plate is widely used in engineering machinery, mining machinery, coal mining machinery, environmental protection machinery, metallurgical machinery and other product parts. Excavator, loader, bulldozer bucket plate, blade, side blade, blade.

The correct choice of billet type, section shape, size and weight are of great significance to 09CUPTIRE-A steel grade steel rolling production. Steel rolling production has certain technical requirements for raw materials, such as steel type, section shape, size, weight, and surface quality. The consideration of these technical requirements is necessary to ensure the quality of steel. It should also be specifically considered when determining and selecting the blank. The 09CUPTIRE-A steel grade rolling method can be divided into cold rolling and hot rolling according to the rolling temperature.

The company will rely on its good reputation, excellent hot-rolled plates, steel pipes, steel structure products, and intimate 09CUPTIRE-A steel grade after-sales service to customers. I would like to express my heartfelt thanks to the old and new friends and customers who have always given care, support and help to the company! The company sincerely hopes to establish a long-term cooperative relationship with them, mutual benefit and common development. Welcome to come and visit our 09CUPTIRE-A steel grade steel mill.
