بالنسبة للفولاذ المقاوم للصدأ على الوجهين ، كم تعرف؟

دوبلكس الفولاذ المقاوم للصدأ (Duplex Stainless Steel, hereinafter referred to as DSS), refers to the ferrite and austenite content of each account for about 50% general is a youthful appearance also need to achieve at least 30% Stainless Steel.

Duplex stainless steel is a collection of excellent corrosion resistance, high strength and easy processing, and many other excellent performances in one class of steel. Its physical properties are between austenitic stainless steel and ferritic stainless steel, but it is more close to ferritic stainless steel and carbon steel.

Duplex stainless steel in chloride pitting and crevice corrosion resistant ability is chromium, molybdenum, tungsten, and nitrogen content function, can be similar to the 316 stainless steel, can also be 6% higher than that of water use stainless steel such as Mo austenitic stainless steel.

All the ability of resistance to chloride stress corrosion fracture duplex stainless steel were significantly stronger than austenitic stainless steel 300 series, and its strength is significantly higher than that of austenitic stainless steel, at the same time showing good plasticity and toughness.

Duplex stainless steel manufacturing and austenitic stainless steel have many similarities, but there are important differences. The high alloy content of duplex stainless steel and high strength requirements to make some changes in the manufacturing process.
