Duplex steels also have higher strength. For example, a Type 304 stainless steel has a 0.2% proof strength in the region of 280 MPa (41 ksi), a 22%Cr duplex stainless steel a minimum 0.2% proof strength of some 450 MPa (65 ksi) and a superduplex grade a minimum of 550 MPa (80 ksi). [6]

However, duplex stainless steel can be susceptible to a phenomenon known as 475 °C (887 °F) embrittlement or duplex stainless steel age hardening, which is a type of aging process that causes loss of plasticity in duplex stainless steel when it is heated in the range of 250 to 550 °C (480 to 1,020 °F).

In early 2015, China Steel (Taiwan) increased its holding in the plant from 5% to 25%, investing c. $940 million into the development of the plant. [9] In mid 2015 JFE Steel (Japan) acquired a 5% stake ($215.2 million) in the plant. [10] In late 2015, the plant outputted the first hot rolled coil manufactured in Vietnam. [11] "
Virtually generated microstructure of dual-phase steel. [1]Dual-phase steel (DP steel) is a high-strength steel that has a ferritic–martensitic microstructure. DP steels are produced from low or medium carbon steels that are quenched from a temperature above A 1 but below A 3 determined from continuous cooling transformation diagram.
The Ministry of Industry and Trade (MOIT, Vietnamese: Bộ Công thương) is the government ministry in Vietnam responsible for the advancement, promotion, governance, regulation, management and growth of industry and trade.
The Vietnamese Wikipedia initially went online in November 2002, with a front page and an article about the Internet Society.The project received little attention and did not begin to receive significant contributions until it was "restarted" in October 2003 [3] and the newer, Unicode-capable MediaWiki software was installed soon after.
