A. Astm A276 bar profile standard, it is stipulated that this steel does not contain Ni element.
B. For bars, wires, profiles, bright [SCALE STEEL]products and related semi-finished products, the maximum sulfur content is 0.030%.
The Performance Characteristics Of：
(1) Good corrosion resistance, corrosion resistance of general atmosphere and a variety of media.
(2) Low work hardening rate, easy to bend and forming processing.
(3) Good mechanical properties, [SCALE STEEL]high temperature resistance and oxidation resistance up to 816℃.
(4) through the appropriate processing, such as bright annealing, mirror processing, can obtain a good surface and improve the corrosion resistance.
(5) poor weldability.Proper heat treatment shall be carried out before and after welding.
(6) Not adding nickel and molybdenum and [SCALE STEEL]other precious alloys, with cost advantages.
430 is a more economical choice than 304, steel has a series of advantages, low thermal expansion rate, excellent formability and [SCALE STEEL]oxidation resistance, more used in general atmosphere or mildly corrosive environment, such as kitchen POTS, household appliances, automotive interior and exterior decoration, architectural decoration, etc..
