SS 409 Stainless steel bar bars

SS409 stainless steel is a ferritic stainless steel commonly used in machinery, construction and other projects. Due to the presence of austenite grains, its mechanical properties are greatly improved. And due to the addition of many alloy elements, the strength and hardness are also greatly improved.

SS409 stainless steel bar is a general purpose ferritic stainless steel with the following features:

Cost-effectiveness: SS409 is known for its low cost, which makes it an economical choice in many applications.

Heat resistance: It has good heat resistance and can withstand high temperatures without losing its structural integrity.

Resistance to average strain: SS409 is able to resist average strain, which means it is able to maintain its shape when subjected to deformation.

Chemical composition: Its chemical composition mainly includes iron (Fe), carbon (C), chromium (Cr), nickel (Ni), manganese (Mn), silicon (Si), phosphorus (P), and sulfur (S). These elements work together to give the steel the desired physical and chemical properties.

Corrosion resistance limitations: Although SS409 has some corrosion resistance, it is not as corrosion resistant as other types of stainless steel, such as austenitic stainless steel, due to its lower chromium and nickel content.

Machinability: In most cases, SS409 needs to be preheated before welding to improve its weldability. The preheating temperature is usually between 150 and 260 degrees Celsius.

Applications: SS409 is commonly used in the automotive industry for non-appearance parts such as brakes, rotors, pipes and engine components. It is also used in other applications that require low cost and moderate corrosion resistance.

Composição do aço inoxidável

O aço é uma liga de ferro e carbono. Os aços inoxidáveis são aços que contêm pelo menos 10,5% de crómio, menos de 1,2% de carbono e outros elementos de liga. A resistência à corrosão do aço inoxidável e

As propriedades mecânicas podem ser melhoradas pela adição de outros elementos, como o níquel, o molibdénio, o titânio, o nióbio, o manganês, etc.
