1.4529 Super Austenitic Stainless Steel Plate

1.4529 stainless steel plate is a stainless steel containing 16% to 18% chromium, titanium and aluminum and other elements. It has good corrosion resistance and high temperature performance and is widely used in the manufacture of automobile exhaust systems, water heaters, household appliances, etc.

The magnetism of 1.4529 stainless steel plate varies under different compositions and heat treatment conditions, and is usually divided into two types: magnetic and non-magnetic. Impurity elements have a great influence on the performance of 1.4529 stainless steel plate, the most important of which are sulfur and phosphorus

The chemical composition of 1.4529 stainless steel plate is: chromium (Cr): 16.0-18.0%, nickel (Ni): 10.0-14.0%, molybdenum (Mo): 2.0-3.0%, silicon (Si): ≤1.00%, phosphorus (P): ≤0.045%, sulfur (S): ≤0.030%. Arc welding is the process of heating 1.4529 stainless steel plate to a molten state using an arc and solidifying it through the molten pool to form a weld.

Feature :

1、High strength and good mechanical properties

1.4529 stainless steel plate has high tensile strength and yield strength, and can withstand large loads and pressures. This feature enables it to perform well in high-strength and high-stress working environments, such as aircraft fuselages, engine components and other aerospace applications. At the same time, its good mechanical properties are also reflected in good toughness and ductility, ensuring stable performance under various complex working conditions.

2、Excellent corrosion resistance

1.4529 stainless steel plate is particularly outstanding in corrosion resistance. Its alloy composition contains a high proportion of nickel (24%~26%), molybdenum (6%~7%) and copper (1.5%~2.5%). These elements work together to enable the stainless steel to operate stably for a long time in harsh environments such as strong acid, strong alkali and salt corrosion. Especially in a corrosive environment containing chloride ions, 1.4529 stainless steel plate has excellent corrosion resistance, can effectively resist chloride ion stress corrosion, and protect equipment from damage.

3、Good processing performance

1.4529 stainless steel plate not only has excellent performance, but also has good processing performance. It can be cut, bent, welded and processed to meet the different needs of users. Although its high alloy content makes it relatively difficult to process, the smooth processing can be ensured by adopting appropriate processing measures and techniques. In addition, this stainless steel also has good weldability and can be processed by a variety of conventional welding methods, further broadening its application areas.
