309S Stainless steel bar bars

309S is a free-cutting stainless steel containing sulfur and selenium respectively. It is used in places where free-cutting and high surface finish are required. 309S stainless steel improves cutting performance and high temperature bonding resistance. It is most suitable for automatic lathes, bolts and nuts. To improve the performance of the steel, no more than 0.60% of molybdenum can be added to the steel, which can resist ablation. The product has good cutting performance and burning and corrosion resistance. Mechanical properties of 309S stainless steel After annealing and stress relief, the tensile strength is 515MPa, the yield strength is 205MPa, and the elongation is 40%.

Corrosion resistance
Contains high chromium (22%-24%) and nickel (12%-15%) elements, forming a dense oxide film, which can protect the steel surface in high temperature and corrosive environments, and has better corrosion resistance than SUS304 stainless steel. ‌

Heat resistance
Can withstand repeated heating below 980℃, and still maintain strength and toughness at high temperatures, suitable for 800-1000℃ working environments. ‌

Processing performance
Adding sulfur elements, the friction during cutting is small, the surface finish is high, and it is suitable for precision processing. ‌

Applicable scenarios
Widely used in high temperature and high pressure scenarios such as boilers, industrial furnaces, and chemical equipment, and also suitable for precision machining. ‌

Composición del acero inoxidable

El acero es una aleación de hierro y carbono. Los aceros inoxidables son aceros que contienen al menos 10,5% de cromo, menos de 1,2% de carbono y otros elementos de aleación. La resistencia a la corrosión del acero inoxidable y

Las propiedades mecánicas pueden mejorarse aún más añadiendo otros elementos, como níquel, molibdeno, titanio, niobio, manganeso, etc.
