Company NewsWulian Yihe Industry and Trade Co., Ltd. is a professional manufacturer of 310S high temperature resistant stainless steel balls. With years of in-depth experience in the micro steel ball industry, we are equipped with a full-process production line, and can customize full-spec
310S steel balls from 0.8mm to 12.7mm, which are suitable for complex working conditions such as high temperature and corrosion. As a direct source manufacturer, we provide direct supply with controllable quality and stable lead time. We support sample testing and
mass customization, and provide authoritative material inspection reports.
Material Standard: 310S (0Cr25Ni20 / 2520) stainless steel, chemical composition complies with Chinese national standards (GB),
with Cr≥24% and Ni≥19%, featuring excellent high temperature resistance, oxidation resistance and corrosion resistance.
Size Range: 0.8mm - 12.7mm (mainly micro steel balls, special sizes can be customized according to customer requirements).
Precision Grade: G100 to G1000, with high roundness, excellent surface finish and strong dimensional consistency.
Processing Technology: Cold Heading → Flashing → Solution Heat Treatment (quenching at 1050-1100℃) → Fine Grinding →
Polishing, to ensure the high temperature stability and mechanical properties of the steel balls.
Surface Treatment: Fine polishing, mirror polishing, burr-free and scratch-free, surface roughness can be customized according to
requirements.
Quality Assurance: Each batch of products is provided with a chemical composition report, hardness test report and roundness
test report.
High Temperature Resistance: Can work stably in a high temperature environment of 1100-1200℃ for a long time, not easy to
oxidize or deform, suitable for high temperature furnaces, metallurgical equipment and other scenarios.
Corrosion Resistance: Resistant to corrosion by strong acids, strong alkalis and high-temperature flue gas, suitable for corrosive
working conditions in chemical industry, petrochemical industry, desulfurization and denitrification fields.
High Precision: Focus on micro steel ball production with advanced equipment and minimal dimensional error, to meet the
high-precision requirements of precision machinery, high-end bearings and other fields.
Direct Source Manufacturer: Self-owned production line with no intermediate links, high cost performance, flexible production
cycle adjustment, and support for small batch customization (MOQ 50kg).
Widely used in high temperature furnace accessories, metallurgical equipment, petrochemical machinery, chemical reaction kettles,
desulfurization and denitrification equipment, precision bearings, valves, high-end instruments, etc. Especially suitable for industrial
scenarios with high temperature, corrosion and strict quality requirements, it is the optimal alternative to ordinary stainless steel balls.
Wulian Yihe Industry and Trade Co., Ltd. adheres to the principle of quality first. All 310S steel balls are made of high-quality raw materials, and each production process is strictly controlled to ensure that the products fully meet customer requirements. We support
customized production, have a complete after-sales system, and provide customers with professional technical support and services
throughout the whole process.
