1 Introduction
38CrMoAl high aluminium steel is a high temperature and corrosion resistant alloy. It has a very high yield strength and tensile strength and its creep resistance is significantly better than that of other high temperature alloys. This makes it the ideal material for a variety of demanding applications, including steam pipes, high temperature engines, chemical processing and more. Due to its superior properties, the demand for 38CrMoAl high aluminium steel is ever-increasing and it is quickly becoming the steel of choice for many manufacturers.
2 Production Process
The production of 38CrMoAl high aluminium steel starts with the use of continuous casting. The continuous casting process is an efficient and cost-effective method of producing large quantities of steel in a single heat. This process begins with a large steel slab, which is cast into a continuous slab. This slab is then heated and rolled in a rolling mill to produce the desired shape and dimensions. The rolling mill can be adjusted to produce the required dimensions with a tight tolerance. Next, the steel is cooled and semi-finished products can be produced.
The semi-finished products need to be further processed to improve the properties of the steel. This is done by introducing heat treatment. Heat treatment involves the heating and cooling of the steel in order to change its mechanical properties. It is done in a vacuum in order to reduce the risk of oxidation. This process is necessary in order to achieve the desired properties.
Finally, the semi-finished products are inspected for quality. This includes a visual inspection to check for any surface defects such as cracks or porosity. The dimensions are also checked to ensure that they meet the required specifications. The steel is then ready for use in the production of various products.
3 Conclusion
38CrMoAl high aluminium steel is an alloy with superior properties that make it perfect for many different applications. The production of this steel begins with the use of continuous casting which produces the semi-finished products. These are further processed with heat treatment in order to optimize their properties. Finally, the semi-finished products are inspected to ensure that they meet the required specifications. With its superior strength, corrosion resistance and superior creep resistance, 38CrMoAl high aluminium steel is quickly becoming the steel of choice for many manufacturers.
