Efficiently Solving Steel Heat Treatment Challenges: Xingyi High-Temperature Anti-Decarburization Coating (XG-20X Series)
In the steel metallurgy and heat treatment industry, medium and high carbon steels often face challenges of decarburization and descaling during high-temperature heating. Decarburization leads to a reduction in carbon content on the steel surface, affecting its hardness, wear resistance, and mechanical properties, and may even cause micro-cracks. The iron oxide scale formed at high temperatures, due to its dense structure and strong adhesion, is difficult to remove, increasing subsequent grinding efforts and production costs.
As an innovator in high-temperature oxidation resistance technology, Xingyi New Material Technology (Chengdu) Co., Ltd., based on years of technical accumulation, has developed the professional high-temperature anti-decarburization and easy-descaling coating XG-20 series, aiming to efficiently address the above industry pain points.

I. Product Overview and Core Advantages
The XG-20 series high-temperature anti-decarburization coating for billets is a composite water-based slurry composed of nano-micro inorganic mineral powders and high-temperature bonding additives. It is uniformly sprayed onto the billet surface, forming a dense isolation protective layer at high temperatures. The uniqueness of this coating lies in its dual protective mechanism, making it excellent in anti-decarburization and easy descaling.
? Efficient Anti-Decarburization: The coating effectively isolates oxidizing atmospheres, inhibiting the loss of carbon elements on the billet surface. Within the heating temperature range of 950°C to 1,250°C, the coating can reduce decarburization layer depth by more than 50%. For specific steel grades and production environments, the full decarburization layer can even be reduced by over 90%, ensuring product surface performance.
? Easy Descaling Feature: Unlike traditional coatings, XG-202 can modify the structure of the iron oxide scale, causing it to automatically peel off after cooling or be easily removed under high-pressure water. This significantly simplifies the descaling process, reduces subsequent grinding intensity, and thereby improves production efficiency.
