    The basic concept of duplex stainless steel is to produce a chemical composition that makes the mixture of ferrite and austenite substantially equal. The balance of these two phases provides the following:<a href="">china steel new sus304 stainless steel coil</a> Higher strength. Current duplex stainless steel grades 0.2% PS range is 400-550MPA, which can reduce the weight by reducing the cross-section thickness. This advantage is the use of ---- pressure vessels such as storage tanks, structural applications, such as bridges and so on.<a href="">316 ���֧�اѧӧ֧��ѧ� ���ѧݧ� ���ԧ�� ���֧� / ����ѧݧ� ���ԧݧ�ӧ�� ���֧ݧ֧٧�</a> Thicker cross section, with good weldability. Although it is not as simple as austenite, but much better than ferrite. Good toughness, lower than the ferrite, especially to minus 50 degrees Celsius, stretching to minus 80 degrees Celsius. Anti-stress corrosion cracking - Standard austenitic steel is particularly susceptible to this type of corrosion. Some of the most important applications that take advantage of this include: hot water tanks, breweries, refineries, swimming pool structures.<a href="">SS430 2b ba grade Stainless Steel coil and sheet</a> The important components of stainless steel can be divided into ferrite and austenite, each element is conducive to a structure or another. 430 has a ferrite advantage, ferrite in the structure is also true. 304 grade can become austenite, mainly through the use of about 8% nickel. In order to achieve about 50% of the double steel structure at each stage, it is necessary to maintain a balance between austenite and ferrite. This explains why the nickel content of double steel is usually lower than the austenite.<a href="">Acero galvanizado de densidad de mercado chino</a>
