A comprehensive comparative test will be conducted on various materials, the presence or absence of surface treatment, the types of surface treatment, and the presence or absence of high-temperature oxidation tests!
Our company conducted an evaluation of the seizure resistance of bolts and nuts. We performed a comprehensive comparative test using various materials, the presence or absence of surface treatment, types of surface treatment, and the presence or absence of high-temperature oxidation tests, based on the anti-seizure treatment test methods. The test types correspond to the anti-seizure treatment test standards of the Japan Water Works Association JWWA G 113 and G 114. For details such as test results, please download and view the catalog. 【Test Conditions (Partial)】 ■ Tightening Torque: 100 N·m ■ Nut Movement Distance During Tightening: 5–10 mm (Target Value) ■ Number of Tightening Cycles: 5 ■ Test Specimen Size: Hex Bolt and Nut, M16×90 (Partially Threaded) ■ Test Specimen Material: SUS304J3, Silicoloy A2 (OAG), SUH660 (ST) *For more details, please refer to the PDF document or feel free to contact us.

Company information
Silicolloy is a revolutionary new material that contains a large amount of silicon (silicon) and was developed using pure domestic technology. Silicolloy is a super alloy that possesses high strength, heat resistance (high-temperature oxidation resistance), corrosion resistance, wear resistance, high hardness, and low dimensional changes during heat treatment, all in one steel. Currently, many engineers (technicians and designers) are advancing its commercialization, contributing to new product development and total cost reduction through increased longevity. There is 'Silicolloy A2', which excels in overall balance as a precipitation-hardened stainless steel, and 'Silicolloy XVI', which has the highest hardness in the world as a precipitation-hardened type. Those who require both corrosion resistance and high hardness should not miss it!
