430 STAINLESS STEEL TUBE

430 stainless steel tube

430 stainless steel tube, also known as 1.4016, is recognized for its corrosion resistance due to a chromium content of 16-18%. Ideal for mildly corrosive environments where cleanliness is key, it is widely used for kitchen appliances, automotive trims, and interior architecture. Its excellent polishability offers finishes from mirror-like to brushed, important for aesthetic applications. Although non-hardenable by heat treatment, annealing can increase its ductility which allowing for easier shaping during fabrication. With moderate formability and weldability, its cost-effectiveness makes it a popular choice for durable and visually appealing projects.

430 stainless steel tube FAQ

Concerning magnetic properties, 430 stainless steel tube, with its lower nickel content compared to 439, exhibits reduced magnetism. Regarding thermal resistance, both 430 and 439 perform similarly, tolerating temperatures up to 815°C (1500°F). The higher carbon content of 430 imparts greater hardness relative to 439. From a cost perspective, 430 is more economical than 439, attributed to its lower chromium content.
Like other 400 grade stainless steel, 430 is magnetic because of its iron content.
The high chromium content and minimal nickel in 430 stainless steel tubes confer non-toxic properties, enhancing stability and corrosion resistance. The chromium oxide layer formed on the surface acts as a barrier, reducing metal ion leaching. These features make 430 stainless steel an apt choice for hygienic applications within the food, culinary, and medical industries, where minimal allergenic risk is crucial.
It is EN 1.4016.
Regarding composition, 430 stainless steel tube contains up to 0.5% nickel and 16-18% chromium, compared to 304's 8-11% nickel and 18-20% chromium. In terms of corrosion resistance, 430 is adequate, while 304 is superior. Magnetism differentiates them further: 430 is magnetic, 304 is not. Cost-wise, 430's lower nickel and chromium content make it more economical than 304. Therefore, 430 may be a better choice for cost-sensitive projects, whereas 304 is better for applications requiring higher quality and performance. Ultimately, the choice should be tailored to specific needs, and MW will do our best to meet all your needs.
The maximum operating temperature for 430 stainless steel tubes is typically around 815°C (1500°F). However, continuous operation at this temperature may lead to a reduction in both corrosion resistance and mechanical properties.
430 stainless steel tube typically has a thermal conductivity of around 26.1 W/m•K at 100°C, which is lower than that of austenitic stainless steels. This property is important in applications where heat transfer is a consideration.
The coefficient of thermal expansion for 430 stainless steel tube is about 10.3 x 10^-6/°C, which is slightly lower than austenitic grades, making it less susceptible to deformation under temperature changes.
Yes, 430 stainless steel tubes offer good resistance to sulfur-containing atmospheres, making it suitable for some industrial applications where sulfur compounds are present.
