Rolling Characteristics of High-Alloy Steel and Quality Steel
High-alloy steel is a kind of commonly used special steel, which has the characteristics of high strength, good machinability and good plasticity and formability. The alloying elements in it generally account for a large proportion, so it has higher metallurgical properties. The quality steel is also a kind of moderately priced special steel, with high strength and superior performance, with good machinability and weldability. It is widely used in manufacturing and engineering industries, and its main characteristic is high yield strength and good machinability. This paper mainly introduces the rolling characteristics of high-alloy steel and quality steel.
First of all, the rolling characteristics of high-alloy steel. High-alloy steel is generally made of main composition and alloy composition, and its main composition is carbon composite steel. It has higher requirements for cast and roll performance, so the quality of casting and rolling must be high, and the choice of alloy is strict. To ensure the excellent performance of high-alloy steel in practice, special rolling machining process and corresponding rolling materials must be adopted. On the one hand, the quality of rolling materials needs to meet the requirements of the Ministry of Metallurgical Industry; on the other hand, special processing techniques need to be introduced to ensure that the manufactured high-alloy steel has excellent performance.
Quality steel is a kind of ultra-high strength steel, which is worth mentioning because of its higher yield strength and superior processing performance. Quality steel is mainly produced by special rolling process, which requires strict control of the rolling speed and the amount of reduction during rolling. In addition, the cooling rate after rolling should be strictly controlled to ensure that the quality steel has high yield strength without losing its superior processing performance. At the same time, the selection of rolling materials, rolling fixtures and rolling tools should be based on the performance and usage requirements of quality steel, so that the components manufactured with it can have high strength and excellent performance.
In conclusion, the rolling characteristics of high-alloy steel and quality steel have great differences due to their distinct metallurgical properties and usage requirements. High-alloy steel needs to be produced by special rolling process and corresponding rolling materials and special processing techniques must be introduced to ensure that the manufactured high-alloy steel has excellent performance. Quality steel needs to be produced by special rolling process and corresponding rolling materials, with strict control on the rolling speed, reduction amount and cooling
