Unlocking ODS Powder Metallurgy: Benefits of SGHT Heating Alloys

2026-04-02

As a practitioner in the industrial production field, when choosing electric heating alloy products, you may often be confused: why is SGHT called a high-end product even though its price is slightly higher than other FeCrAl electric heating materials? In fact, the answer is simple — the core competitiveness of SGHT comes from the ODS powder metallurgy process it adopts. For customers who have never used SGHT, understanding the ODS powder metallurgy process will help you understand why it can stand out in various high-temperature working conditions and become the first choice for high-end production.

First of all, let’s explain in plain language: what is ODS powder metallurgy process? Simply put, it is a high-end material preparation technology different from the traditional smelting process. Its core is to uniformly disperse ultra-fine nano-oxide particles (usually less than 50 nanometers) into the FeCrAl alloy matrix through mechanical alloying technology, and then form a dense and high-performance electric heating alloy material through hot isostatic pressing, hot extrusion and other consolidation treatments. Unlike the disadvantage of traditional smelting process which is "one-pot casting" and easy aggregation of oxide particles, the ODS process can make nano-reinforced particles evenly distributed inside the material, just like putting a "nano protective coat" on the alloy matrix, fundamentally improving the comprehensive performance of the material.

For customers in the industrial production field, the advantages of this process directly correspond to the core needs in production — stability, durability and high temperature resistance. In various industrial production processes such as high-temperature heating, annealing and sintering, it is in a high-temperature environment above 1000℃ for a long time. Ordinary electric heating alloys are prone to softening, oxidation, fracture and other problems, requiring frequent replacement, which not only increases costs but also affects production efficiency. As a high-end FeCrAl electric heating alloy adopting ODS powder metallurgy process, SGHT perfectly solves this pain point.

The three core advantages endowed by the ODS process are the key to SGHT’s high-end positioning, which are incomparable with ordinary products.

First, it has excellent high-temperature resistance, with a maximum service temperature of 1420℃, far exceeding that of ordinary FeCrAl electric heating alloys. It can easily adapt to various high-temperature production conditions and maintain stable performance even in long-term continuous operation.

Second, the service life is greatly extended. The uniform dispersion and strengthening effect of nano-oxide particles significantly improve the oxidation resistance and creep resistance of SGHT, making it not easy to fuse or break. Its service life is 3-5 times that of ordinary electric heating alloys, greatly reducing replacement costs and shutdown losses.

Third, the performance stability is extremely strong. The ODS process can effectively avoid the problems of uneven material composition and performance fluctuation in the ordinary process. In long-term high-temperature work, SGHT has precise temperature control and extremely low failure rate, which can ensure the continuity of industrial production and reduce the increase in defective rate caused by equipment failure.

Some customers may ask: does high-end technology mean high cost? In fact, it is not. Although the initial purchase cost of SGHT is slightly higher than that of ordinary products, relying on the long service life and low failure rate brought by the ODS process, it can greatly reduce the hidden costs such as later replacement labor and shutdown losses. In the long run, it is more cost-effective. As a high-end core product of Beijing Shougang Gitane New Materials Co., Ltd., SGHT adopts ODS powder metallurgy process, relying on Shougang’s strong material R & D strength, to land high-end technology into practical products that meet the needs of the industrial production field. It not only solves the pain points of ordinary electric heating alloys, but also provides support for industrial enterprises to achieve efficient, stable and low-cost production.

At the same time, we also recommend SGHYZ high-performance FeCrAl electric heating alloy, which is customized for conventional industrial working conditions and complements SGHT to cover the entire scenario of industrial production. Whether it is SGHT needed for harsh high-temperature working conditions or SGHYZ suitable for conventional working conditions, they can rely on high-quality materials and advanced technology to help industrial enterprises get rid of the internal consumption of low-quality products and achieve long-term stable profitability.

Understanding the ODS powder metallurgy process means understanding the confidence of SGHT’s high-end positioning. Choosing SGHT is choosing a worry-free, efficient and low-cost production guarantee.
