AISI P20+Ni Steel Manufacturing Process

DONGGUAN, China - Oct. 7, 2023 - PRLog -- P20+Ni steel is a high-quality plastic mold steel with excellent performance. Its manufacturing process includes the selection of raw materials, smelting, continuous casting, rolling, heat treatment, and other links. Each step of the manufacturing process has a critical impact on the quality and performance of AISI P20+Ni steel. This article will introduce the manufacturing process of AISI P20+Ni steel, including some key steps and technologies from raw materials to finished products, to ensure the excellent quality of the final product.

1. Prepare Raw Materials
Before the smelting stage of AISI P20+Ni steel, the first step is to select suitable high-quality raw materials. The content of elements will directly affect the performance of the steel, so it is necessary to strictly control its content and purity when selecting raw materials to ensure that P20+Ni steel The chemical composition of the steel meets the standard requirements and the uniformity and performance stability of the steel.

2. Smelting
In the smelting process of AISI P20+Ni steel, the raw materials that have been batched and mixed are first put into an electric arc furnace for high-temperature smelting to form molten steel. The molten steel after smelting needs to be refined and tempered. By heating and maintaining a specific temperature, common methods include vacuum treatment, redox treatment and tapping decarburization treatment. Through these technical means, the impurities and bad phases in the raw materials can be eliminated, the purity and uniformity of the steel can be improved, and a finer and uniform grain structure and a uniformly distributed liquid alloy can be formed.

In this process, it is necessary to strictly control the content of alloying elements added, melting temperature and time, etc., to ensure the full dissolution and uniform distribution of alloying elements, and to ensure the purity and fluidity of molten steel.

In summary, the manufacturing process of AISI P20+Ni steel includes key steps such as raw material preparation, smelting, casting, rolling, heat treatment, surface treatment, and machining. Every step of these manufacturing processes affects the quality and performance of P20+Ni steel, so it is necessary to strictly control the relevant parameters of each step in order to produce the highest quality DIN 1.2738 / AISI P20+Ni steel.
