Gratex Belt: The Ultimate High-Temp Solution for Powder Metallurgy Production (AISI314/SUS310S)

In powder metallurgy (PM) production, where precision and consistency are non-negotiable, choosing the right conveying system is a decision that directly influences your bottom line. For manufacturers seeking a reliable, high-performance conveying solution, the gratex belt stands out as an industry-leading choice—especially when crafted from premium AISI314 or SUS310S stainless steel. Engineered to thrive in the harsh, high-temperature environments of powder metallurgy processes, the gratex belt ensures seamless material handling, reduces downtime, and safeguards product quality from start to finish.

Powder metallurgy operations, such as sintering, debinding, and heat treatment, expose conveying equipment to extreme temperatures and corrosive atmospheres—conditions that ordinary belts simply can’t withstand. That’s why our gratex belt is specifically manufactured with AISI314 or SUS310S stainless steel, two alloys celebrated for their exceptional heat resistance and durability. AISI314 stainless steel, with its high chromium and nickel composition, offers superior oxidation resistance up to 1150°C (2102°F), making it ideal for mid-to-high temperature PM stages like pre-sintering. SUS310S, a low-carbon grade of 310 stainless steel, takes heat resistance to the next level, enduring temperatures up to 1200°C (2192°F) while resisting corrosion from reactive gases common in sintering furnaces. With a gratex belt made from these materials, you can trust consistent performance even in the most demanding PM environments.

Beyond its premium material composition, the unique structural design of the gratex belt makes it perfectly suited for powder metallurgy applications. Composed of alternating left-right spiral wires connected by sturdy straight rods, the gratex belt features a flat, stable conveying surface that prevents costly powder leakage and ensures gentle handling of delicate green compacts. The open mesh structure of the gratex belt is another key advantage: it enables excellent air permeability, facilitating optimal heat transfer during sintering and efficient air circulation during cooling. This not only improves the uniformity of sintered parts but also shortens cooling cycles, boosting your production throughput without compromising quality.

The gratex belt integrates seamlessly into every critical stage of powder metallurgy production. During compaction, its smooth surface preserves the dimensional accuracy of green parts, avoiding scratches or deformities. In sintering furnaces, the gratex belt’s high-temperature resistance and structural integrity prevent warping or breakage, even under prolonged exposure to extreme heat. Post-sintering, the open mesh design accelerates cooling by allowing air to flow freely around finished components, reducing thermal stress and ensuring product stability. Additionally, the AISI314 and SUS310S gratex belt is easy to clean and resistant to wear and tear, minimizing maintenance time and extending service life—critical for maximizing productivity in high-volume PM manufacturing.

For powder metallurgy manufacturers looking to optimize their operations, the gratex belt is more than just a conveying component—it’s a strategic investment. By choosing a gratex belt made from AISI314 or SUS310S, you’re ensuring compatibility with your specific temperature and corrosion requirements, reducing material waste, and enhancing overall production efficiency. Whether you produce automotive components, industrial fasteners, or precision engineering parts, the gratex belt delivers the reliability and performance needed to stay ahead in the competitive PM market.

Don’t settle for subpar conveying solutions that compromise your powder metallurgy production.
