Chanchai Stainless, a Thailand-based company in Bangkok, is a trustworthy producer and supplier of stainless steel 442 nuts suitable for use in corrosion and heat-resistant applications. Famous for precise production and performance in line with international standards, Chanchai supplies 442 nuts of different sizes and thread types to cater to different industrial demands. Stainless steel 442 nuts are designed to be strong and durable for high-temperature exposure and mild corrosive environments. Chanchai provides consistent quality and prompt delivery, satisfying customers in Thailand and overseas markets with dependable fastening solutions.
Stainless steel 442 nuts are produced from a ferritic stainless steel alloy comprising around 17–19% chromium with minimal carbon and minor additions of molybdenum and titanium. This alloy provides good resistance to oxidation, scaling, and corrosion at high temperatures up to approximately 900°C. Nuts have moderate mechanical properties with tensile strength normally in the range of 450–600 MPa. They possess good thermal fatigue strength and retain their dimensions under thermal cycling, thus being appropriate for fastening at high temperatures.
