Chanchai Stainless supplies Stainless Steel 409 Bolts in Bangkok, Thailand. These bolts are appreciated for their cost-effectiveness, durability, and resistance to oxidation. As a ferritic stainless steel, grade 409 offers good protection against exhaust gas corrosion and high-temperature scaling, making it a popular choice for automotive and industrial fastening. They provide moderate corrosion resistance and solid mechanical stability, ensuring reliable performance in environments where both toughness and affordability are crucial. Stainless Steel 409 Bolts from Chanchai Stainless are built to international standards, offering high-quality fastening solutions for industries that require long service life under thermal stress.
Stainless Steel 409 bolts contain chromium (10.5–11.7%), low carbon (<0.08%), and small amounts of titanium or niobium as stabilizers. Their mechanical properties include a tensile strength of 380–450 MPa, yield strength of around 170–240 MPa, and elongation of 20%. They resist oxidation up to 675°C during continuous service, and even higher in intermittent conditions. Although corrosion resistance is lower than that of austenitic grades, Stainless Steel 409 offers cost-effective durability, thermal stability, and weldability for fastening in exhaust and industrial systems.
